Below is the game between Zebediah and Master Level Zebediah: Black Master: White Game Played at: http://www.GetClub.com/Chess.html 1. d4 Nf6 2.c4 e6 3.Nc3 Bb4 4.a3 Bxc3 5.b2xc3 c5 6.d4xc5 Qa5 Here Master Level (White) is a Pawn plus, Still it will loose 7.Bb2 0-0 8.Nf3 Na6 And here starts the killings from Zebediah. 9. Qd4 Nxc5 10. Rd1 Ne4 11. Qe3 Na4 12. Ba1 Nxc3 And now Black is pawn up. 13.Bxc3 Nxc3 14. Qd2 Qxa3 One more Pawn gone. Black is 2 pawn up. 15. Qd6 Qb2 16. Ne4 Qxf8 {No other move left for white} Now white is Queen down for a Rook. 17. Kxf8 Be2 {Saving Mate.} Complete Recorded Game: http://www.getclub.com/playgame.php?id=DM6727&game=Chess It looks like White played silly but it was Master Level which does long calculations. Was there a way by which White could have avoided such traps. In the begiining White was a pawn up, But in just next 8 moves zebediah ruined whites advantages. Was there a way for Master Level to avoid this loss? Bye Sanny Play Chess at: http://www.GetClub.com/Chess.html You can play Chess with Computer as well as Human opponents here.

On average Beginner Level sees till 6 ply But sometimes I have seen it go upto 8th ply also. Play a game with Beginner Level http://www.GetClub.com/Chess.html I am sure you will see atleast 1-2 moves reaching 7-8 ply. Well my Computer is P-IV 2.5 GHz and this is a comman configuration these days.

On my browser the Beginner Level goes till 7-8 ply {each players move} and makes move in 10 seconds.

So twelve ply is six moves by White and six by Black. > On my browser the Beginner Level goes till 7-8 ply {each players move} > and makes move in 10 seconds. I'm sorry but I just don't believe you. Nobody else is getting performance anything like that from your program.

This is the fundamental problem. You seem to think that because Master Level takes a long time to think, it is looking far ahead. Clearly, that is not the case. Your program does not appear to be seeing more than 4 ply or so ahead, if that. A program like Crafty, on my five-year-old computer, sees 4 ply ahead in under a third of a second. You need to figure out that your program is doing with all the time it takes to make its moves, and fix it so that it's seeing further ahead. All this chatter coming from you about making the program stronger-but-slower or faster-but-weaker misses the point. Your program is not making effective use of the time it has, and the result is abysmal play. It the amount of time your program usually takes at even intermediate level, it should be seeing at least 12, possibly as many as 15 ply ahead. It's not. Figure out why, and you'll have a program that doesn't stink.

It would also get into a terrible mess playing the black side of the closed Lopez.
