No. White's best tries include advancing the King, even if he can be driven back or forced to retreat. (This is because the Rook simply can't do what a King can do in close quarters. The Rook is superior in exerting influence /from afar/.) > Then please demonstrate a method by which, after 1...Rc3, White can > advance his king beyond the second rank without allowing an exchange > of rooks that leaves a drawn position. I cannot demonstrate a forced win here, because the position is a theoretical draw; however, I have already discussed the fact that Jose Capablanca routinely won theoretically-drawn positions with all the pawns on one side and one Rook apiece. I could be mistaken, but in general his opposition were often described as chess "masters", perhaps meaning local masters, as opposed to international ones. It requires a swindle; in other words, the opponent must defend poorly, or at least make one crucial blunder. Here, that would include trading Rooks at the wrong time, or allowing the White King to approach and not making him pay dearly by in turn winning his base pawn. I note that, even having set up the wrong position, you came up with Fritz' move, ...Rc3. Am I expected to defeat Fritz-- a player twice my size? In your original answer -- the one I took exception to -- you indicated that it was not known who was on move; to this I will add that the question itself implied that the superior player -- the one trying to win -- ought to be on move, else how can we tell him what he should do next? Thus, my research assumed that the actual position in the link had White on move, and I was surprised to find that we were just one tempo away from a forced win *if* Black traded Rooks. Clicking on "Black to move", I found that he often had just one way to draw and a multitude of table-base-perfect losses, but clicking "White to move" was a different story: here it was necessary for the player of the Black pieces to defend accurately, like a computer.

At the master level, yes. At Yahoo!, I suspect "reasonably competent" has a very different meaning: not often hanging pieces outright. Just look at the original question: "how do I win this?"; does this not tell us that the asker is a weak player, and his opponent has somehow managed to lose a pawn to him? These are no Masters, nor even Experts, nor Class A players, my friend; all things are possible! Most tournament players I know would never ask such a question; Class B or C players would already know the answer, or at least /think/ they know. > > (Things are so much simpler > > with Queens, don't you know, because > > unlike with a Rook, the base pawn can > > be sacrificed in return for a two-man > > mating attack!) > > Yes, and things are so much simpler in a knife fight if someone > hands you an AK-47.

"Logic" is why I jumped in, for you went too far in stating that "the best that could be hoped for" was the Rook-pawn scenario. In my opinion, that is just about the exact opposite of the truth. Your shallow approach is the reason I felt compelled to make any correction; had you given the poor chap a better answer, I would have left it alone, as I did with the recent "Monkee" thread.

Yes, and things are so much simpler in a knife fight if someone hands you an AK-47. It would be so much simpler finding a drink in the Sahara if it was dotted with lakes like Minnesota.

The trouble here is not that White's King cannot move around; it is that White's Rook cannot be utilized to defend the base pawn without becoming inactive; that, and the fact that if Black's Rook keeps the checking distance, it can harry the White King at will with impunity. (Things are so much simpler with Queens, don't you know, because unlike with a Rook, the base pawn can be sacrificed in return for a two-man mating attack!) > An exchange of > rooks in such a situation leaves the black king in fine position to > deal with the white pawns, for example 2.Re3 Rxe3 3.Kxe3 Ke5 and it's > a dead draw. Once again, you have analyzed the **wrong position**. The graphic link at the top of this thread shows the Black King cannot reach the e5 square in one move, since it sits on g6. I daresay this is hardly the first time I have had to point out such a careless error on your part, TK. In order to make heads or tails of what is going on, you really do need to learn to set up the pieces correctly; this is a very common problem for beginners. Here, I'll make it easy for you: http://i25.tinypic.com/1zp6xpx.png Note well where the pieces actually sit on the board: the Black King is on g6, for instance. The King is allowed to move just one square at a time, so you cannot get to e5 in just one move. ---------------------------------------------------------- In the original post, it was not stated who was on-move, and the question itself ,"how do I win this", implied it was White to move (why ask how you can win, if you are behind?). With Black on move, things are even tougher here. -- help bot

Ah, then perhaps you will demonstrate to us, Greg, how White wins from the OP's given position. Or even manages to "advance his king" or "exchange rooks" advantageously, which you consider to be the paths to victory. Advancing the king seems particularly problematic given that the white king is on the second rank and the black rook on the fourth, in the given position. Black plays, say, 1...Rc3, and the white king is likely to stay on his two back ranks indefinitely. An exchange of rooks in such a situation leaves the black king in fine position to deal with the white pawns, for example 2.Re3 Rxe3 3.Kxe3 Ke5 and it's a dead draw. If your point is merely that White can win against stupid moves, and I have seen nothing else from you in this thread, this can hardly be considered any worthwhile insight. It does the OP a disservice, and is yet another example (among many) of your typical laziness.

If you don't wish to discuss your gaffe any longer, I understand-- really, I do. ----------------------------------------------------------------- Personally, I think your shallowness argues strongly against *you* attempting to teach chess. What limits /my/ ambitions in that regard are: 1) Many players are priily interested in booking up on the openings, and here I have little in the way of expertise insofar as rote recitations of main line theory. 2) Chess players in my area are some of the cheapest, tightest people I have ever known. These guys will paw a book they obviously desire, then tell you they can't afford to buy it unless their wife gives her approval. That's a $5 book. A ten dollar book requires prior approval by the wife, the kids, the dog, etc. I expect the same -- if not worse -- when it comes to paying for lessons. 3) Scholastic chess is the key; get some ten-year-olds to take lessons and you are set. Parents *will* spend money for chess lessons, but then, you have to put up with kids who, by and large, fit problem number one above, have little in the way of patience, and who expect "instant results" in the way of consistent, monster-size rating gains. 4) My advice is to get really good at tactics, and for this you don't need a human teacher; Fritz will suffice. I am obsolete, except in my ability to explain the *why* of Fritz's killer moves. -- help bot

First of all, it was later determined to be Black's move here, and the guy asking how to win was apparently the one *down* a pawn. The proper question should then be, "how do I /draw/ this?" Secondly, you forgot to provide the quote of me stating it could be done "by force". Once you provide that quotation, then we can move on to my proof or discussion of how it is done. See: Robert's Rules of Disorder for the proper procedures. > > So the statement that the best that White > > could hope for was such and such, was just > > plain wrong.

Obviously, the conclusion posted by you was mistaken, as I have already shown. It would have been alright if you had taken care to state facts, like the fact that it is a "theoretical draw". This means that with *best play*, the result will be a draw. Too bad you got careless once again, in your usual manner. It was of course I who first mentioned the terms "theoretical draw" and "best play" here, not you. Here is something to mull over, while you are steaming about getting caught in yet another careless error: Jose Capablanca used to win "theoretically drawn" positions in Rook endings *routinely*; sometimes, these positions had all the pawns on the same side of the board! Today, it would be considered something of a disaster if a strong player did not manage to hold such a position, but weak players are every bit as "capable" as the masters of old who lost routinely to GM Capablanca. In their defense, there were normally *more* than just three pawns left; but in defense of weak players, that is only a question of degree (of incompetence). If we wanted to focus on mere questions of degree, we could easily get bogged down on such minuscule errors as miscalculating one's rating at 2300+, rather than 2250ish; but we are not /that/ petty. Indeed, we are the type which forgives accidental errors of no real import, looking to matters of principle as more worthy of our efforts. In that vein, I found your reply to be shallow and, upon due research, erroneous, since there is no reason whatever to assume a weak player will carefully avoid trading Rooks here. When you look at the position after such a trade, it becomes apparent that White wins easily-- *if* he knows what he is doing. Granted, odds are that neither player knows what he is doing, but this tends toward a more random result-- not an automatic draw, as between two GMs. -- help bot

In the original story, the guy who refused to resign had a lost position, right? He was supposedly an evil scum for not resigning, though I believe Larry Evans actually admitted his error after his story was easily debunked by Edward Winter. This is one case where LE admitted he was confused, instead of attacking the messenger or insisting it was "a typo". It did not occur to me to examine the entire screen to see if I could determine the ratings of the two players in /this/ game, until after Sanny mentioned something about it here. To me, it's all a blur-- but then, I am half-blind. I was able to make out that they were playing at Yahoo, which tells me it wasn't GM Dzindzi vs. Gary Kasparov (the damned ICC rating-hogs!). Generally speaking, when I see Rybka or other top players try to win such positions, they do not lock up the pawns, but try hard to maintain their "fluidity". In other words, a Rybka would have pawns at g2 and h2, not g3 and h4-- locked and practically immobile. Come to think of it, this also describes how Gary Kasparov used to handle the Sicilian /opening/, as Black. Oh-- and a Rybka would have pawns on both sides of the board! That makes things a lot more complicated for the defender. Mr. Winter needs to learn that he is not nearly-as-IMportant as Larry Evans; he needs to learn to respect his betters-- even if they just make things up, and if they can't spell and if they can't get their dates or anything else right.

Some people just can't handle it when their analysis is shown to be shallow, lacking in creativity, or just plain mistaken! I checked the endgame table bases to see just how badly Black would need to play before it becomes a theoretical win; much to my surprise, it wasn't all that improbable; any Rook trade on White's fourth rank led to a forced win, and even trades on the third rank could lead to a win if Black's King were in position for defense only, which it obviously is now. So the statement that the best that White could hope for was such and such, was just plain wrong. It turns out that he can try to win this by advancing his King-- but it won't work if the guy who is down a pawn knows his stuff (which he may well not). It's just another small goof-- like all the rest; the thing to do is learn from it; try not to be quite so shallow in your thinking the next time. -- help bot

"Candidate first" is one maxim, but many writers have advised players to advance their Rook-pawns in Rook endings for the simple reason that Jose Capablanca (and others) used to win drawn positions quite frequently in such a way that would have been impossible had the defense traded his Rook-pawn off. I've seen GMs do this "without thinking" in blitz games, but not as a winning attempt (only to avoid losing). If there are any other duffers who doubt the possibility of winning this, I would refer them to the endgame table bases, which indicate a multitude of won positions for White, should Black make a single error (such as trading Rooks unwisely) . In general, a player who asks how to win a theoretically-drawn position is likely to be playing another such player. I still recall a game I had against a well- booked USCF Expert, which resulted in a theoretically-drawn Rook ending. The poor fellow knew he was supposed to keep his Rook a certain place until I advanced my pawn to the sixth rank, then he was to go to the eight rank and harry my King from there. But instead of advancing my pawn, I played a waiting move, and... you guessed it-- he went to the eight rank a move too early, and lost. Of course, I don;t expect either of these two players are nearly Experts... . -- help bot

You are in good mood. In Chess a move cannot be said good on belief tthat suppose that Opponent do not make that move. Yes for very weak players we can assume such things. Help Bot is considering them a weak player who will play bad moves. Remember that story where Rybka lost even after having 10 extra Queens? Result in Chess very much depends on who the Opponent is. Usually for a weak player the opponent is also a weak Player. Why will a master play with beginner? He will try to have a match with Grand Master. Since Terry is ~ 1200 his opponent is also ~1200 So may be they cannot see the correct moves. Bye Sanny Play Chess at: http://www.GetClub.com/Chess.html

Yes, and White could also win if Black does not exchange pawns on g4 when White advances, and instead allows the pawn to ch down and queen. And Black could win if White puts his rook en prise, or if White decides to move only his king and lets it be driven to the back rank and mated. I dare say Pee Wee Herman could win a boxing match against Evander Holyfield if Holyfield stood motionless with his hands at his sides. Further research indicates that if pigs had wings, they'd live in trees.

For the record, the move list shows that the last move was 47.Re3-e5. The position is 8/8/6k1/4R2p/2r4P/6P1/5K2/8 b - - 8 47 > White has no chance to obtain a passed g-pawn.

I'd be interested to know how the pawns got where they did. The usual maxim is `advanced the candidate first' -- that is, the pawn that can potentially become passed. In this case, the g-pawn. The problem here is that White has advanced his h-pawn and left the g-pawn backward and with no chance of becoming a passed pawn.

As usual, TK is mistaken. In this position, White could possibly win if Black makes the mistake of trading Rooks on the wrong square. As the game was not already agreed drawn, it seems likely that the two players are not exactly master-strength, so such an unwise trade is far from impossible. The crucial aspect would be the timing of the trade-- on which squares the two Kings are at the time, and whose turn it is to move. For instance, if White were to interpose on the second rank and exchange Rooks there, his chances of winning are not good. But if Black were to play a check on, say, the forth rank, and after White interposes exchange there, it is likely a forced win. Unfortunately, the trade cannot be forced, and if Black stays on his toes, White cannot *safely* approach to try and force the Rooks off. This is mainly because, if the g-pawn goes, so goes all winning chances right along with it. Were White's pair of pawns closer to the center, things might be different; even so, a *skilled* player could manage a draw even then. In sum, White must *not* advance and trade off his g-pawn. White can attempt to walk his King forward, then trade Rooks or drive the enemy King away from the defense of his h-pawn, but with proper defense, this cannot be forced and the position is therefore a theoretical draw. It is certainly *not* the case that the best that can be hoped for is a trade with only a Rook-pawn remaining; that is essentially a worst-case scenario-- barring a Rook hang or self-mate. -- help bot

I wish I had the full table- bases, so I could more easily provide some examples of positions where White wins perforce. As it is, I have to manually remove the Rooks, then shuffle the Kings around to different positions, and observe the win/draw results. It is very difficult since I know how to draw this; I have to guess just how does a weak player think. Really, it was sooo much easier to attempt this with White to move! > Spelling "cat."
