My First Draw Against Crafty!!
Sort:
were you running a virus check or something in the background? Lots of mistakes there. Just looking at the end position, you have plenty of chances to take the knight and promote your c pawn. 
linux doesnt have viruses. but i dont see any of the chances for the knight and c pawn there.
You should have won, but you should not be claim you have drawn against a computer playing at 2600+ level, because it clearly is performing much lower at 1400 or so. You must have lowered the difficultly setting, which is hard to do if your using xboard or your version of crafty is faultly. Even severe time constraints don't explain 14. Ne5??. 14...Rxf1 15 Kxf1 Bxc6 16 Nxc6 Qf5+ and black has the initiative.
Sac the queen for the knight and u win.
no crafty is set on the highest difficulty.

and its logs show no errors. when crafty hits an error it dies. I was very surprised by ne5 actually but other moves like that in the past have gotten me checkmated in a move or two by crafty.
Of course linux has viruses. Although of course had i remembered you were on linux I would have assumed you didnt bother checking for them ever. Still, it really seems like you were running something else big for the computer to play like that. Or perhaps something is wrong with the program. My CM8000 occasionally messes up and starts making really bad moves and basically refusing to look more than a couple of moves ahead, i think triggered by a bug in one of the time settings.

though i supposed it still might be faulty.

in order to download a virus i would have to download the .tar, extract it, chmod + the *.sh file, make install the *.sh, and then configure it in its /etc/ folder to run optimially . but i dont download strange .tars and execute them. I use the depositories.
well that's like saying i would need to download the .exe and run it, and i dont download strange .exes and run them. There are plenty of ways to get viruses, even for linux.
I think it unlikely to be a virus, but xboard is a bit buggy sometimes. PyChess is a half decent interface for linux and it is more reliable than xboard. It is much easier to specify what chess engine you want to play against and its difficultly level and time per move. I want to get Fritz or Shredder and chessbase in the future because of the better interface and options. Not sure if they work using linux though.
There is a linux version of Shredder, though it is Java based (blech).

I am not aware of any linux versions of Fritz. I run Fritz on my new laptop, which dual boots between Vista and Ubuntu. I also have several virtual machines on my Gentoo linux desktop, for various other games and chess programs.
I'm going to have Crafty annotate the game under Gentoo, which is a quad core machine. I'm curious to see what that reveals.
yeah, didnt mean to imply it was a virus, just that if he was scanning for them it could have bogged down his computer.
55 Q d4+ and push the cpawn

I play crafty on my computer on xboard for fun sometimes but never seem to be able to beat the damn thing, let alone draw it! I finally got my first draw today and I'm very happy even though it seems like the computer made a terrible mistake to me. Though I was ahead in pieces at one point and suppose I could have actually beaten crafty if it wasnt so ...whats another word for crafty? good at building things?
So anyway I'm posting this game to see if anyone here could have helped me actually checkmate it.
here are the settings I used to anyone is interested. I tried to make the hash and pawn hash bigger but for some reason I cant. though it lets me make the end game tables quite big.
pondering enabled.hash table memory = 24M bytes.
pawn hash table memory = 16M bytes.
EGTB cache memory = 512M bytes.
game/5 minutes primary time control
my computer has a centrino duo 2 gigs of ram and runs linux if any of that is important either.
