Subject: Peter win Master Level at GetClub.

Peter played with Master Level using his computer program. Glaurung
2.1

Glaurung 2.1 was thinking for 2 sec / move
GetClub Master Level was thinking: 500 sec / move.

So GetClub was taking 250 times more time, Still GetClub lost the
game.

6. Nf3xd4{392} Ng4xf2{16}

Here on 6th move Glaurung gave sacrifice of its knight for a pawn.

After 40 ply it recover a extra Bishop. Since Master Level cannot see
40 ply deep it overlooked this move.

I am amazed to see how Glaurung find a sacrifice 40 ply deep.

Thanks for your Analysis.

In this game I find a few weaknesses and removed them So that GetClub
plays stronger games.

First of all, Glaurund did not see 40 plys ahead,
(and even if it could, it would not be looking at the
inferior line played by the GetClub program).

This opening is very similar to something folks
around here used to call the Fried Liver Attack,
possibly also known as the Wilkes-Barre.

White erred first of all by playing both e4 and
c4, which weakens the dark squares; careful
defense could alleviate such a problem, but
instead GC tried to calculate its way through
a maze of sharp variations, and lost its way.

Tactically, the simple 4. Be2 would have
circumvented the Knight sacrifice, but this is
a poor arrangement for White. I prefer the
idea of a Kingside fianchetto, even if it may
become necessary to play p-h3 to keep the
Black steed at bay.

Anyway, after the sacrifice on f2 White was
under the gun the rest of the way, and by
mid-game it was clear what the result would
likely be. Take a gander at GetClub's horrific
13. Ra2; this is the sort of thing which so
often comes up in tactical skirmishes, and
is the hallmark of a very confused mind-- er,
chess engine.

In attempting to defend such a precarious
position, a /coherent development/ of the
pieces must be figured out, but GC always
jumbles its men about in a fog of confusion.
This in turn creates numerous opportunities
for the opponent to land a decisive tactical
blow-- or perhaps two or three.

My machine spotted a forced checkmate
as early as the move 35. ... b2, vacating the
b3 square for its Queen. But even before
that, it had Black a piece or so ahead for
many moves. I did not realize that the
attack was quite so powerful; in fact, I had
the impression (though I never played
this line from either side except in casual
blitz games) that White was supposed to
emerge on top-- if he defended perfectly.
After analysing this game, I have changed
my mind.

So then, how does one properly play
this sort of opening? Well, it's hard to go
wrong with the old adage "Knights before
Bishops"; in other words, the early moves
might go:

1. c4 e5

2. Nc3 Nf6

3. Nf3

I suspect that apart from fetching moves
by rote from a database, this sort of thing
can be accomplished by giving a small
bonus for piece-development in the early
opening. Note how moves like 3. e4 do
nothing to promote castling, whereas the
move 3. Nf3 gets one obstruction out of
the White King's way (if he castles King-
side).

One more thing; the move 18. Qd2 is
yet another symptom of a disasterous
approach to defense. Chopping the
Bishop on g4 would have led to a lost
endgame, but guess what? You said
that Glaurung was thinking just two
seconds per move; suppose it got into
a position which it could not solve in just
two seconds? There is a possibility of
a draw.

Keeping all the pieces on just makes
it that much easier for the attacker to
stumble upon a forced mate-- even
with just two seconds per move; and
the defender? The extra pieces get in
one another's way.

My suggestion is to simply remove
GetClub's opponents' QN before
starting play. Then, instead of one
side losing the whole way, we would
see a true contest of sorts. This
would also effectively eliminate the
whole issue of computers playing
openings by rote; both sides would
calculate and evaluate and only then
decide upon their own moves.

Restart game by Rebooting So that new version of the game starts.

I have deleted this game from database. So that when you restart you
can start a new game.

With the weakness removed the GetClub will play much stronger now.

I have started a new game. It isn't finished yet, but after getclub
played 19. Bxe6, it looks like it will be an easy win for Glaurung.

The game is finished now. As expected, there was nothing getclub could
do to save the game after 19. Bxe6.

There was a weakness in the GetClub game that was removed just now.

If you are playing a new game Just restart your Computer So that you
can play with the improved version of GetClub.

There was one weakness in the game that was removed. So that Now it
will not fall in such traps.

What kind of weakness? I had already started a new game, see below.
Do you think getclub has made any bad moves so far because of this
weakness? I can terminate this game and start a new one if you want
to. Or is it enough to just reboot the computer and continue this
game?

Yes, I saw that thread.

Still the Moves after 4...... Ng4 were forced moves.

As 5. d4 was the only move to save the f2 pawn. As f2 pawn was being
attacked by Knight & Bishop.

After 5..... exd4, 6. Nxd4 was the only move else GetClub would be a
pawn down.

6.... Nxf2 was the gambit.

To avoid This gambit GetClub should have seen it at 3. Nf3.

But at N-f3 GetClub found There was nothing wrong. And after that all
moves were forced moves.

Was Glaurung able to see this advantage when it played 3... N-g4?

As per below data even Glaurung was unable to see this gambit at move
3... Ng4 As at move 4 it shows a score of 60 points. What was tthe
score at Move 3?

Only after 6 forced moves this gambit took place.

Here is data extracted from the glaurung log file. The table shows
move number, search depth, score, thinking time and principal
variation.

Yes it was. As you can see from the log file, glaurung thought that
getclub should play 6. Na4 instead of 6. Nxd4. That way it would only
have lost a pawn, instead of getting the king in the middle and losing
even more.

It saw a way to avoid the worst problems by playing 6. Na4 instead of
6. Nxd4. That's why the score was only 60.

It didn't. See my response in the other thread. Glaurung saw the
knight capture after a 6 ply search which took 13 milliseconds.
