Martillo vs. SMIRF 1.66g, 1-0 in 63
Here is a link to the game (with SMIRF 1.66g score and comments)
Martillo vs. SMIRF
The Martillo programmer has had problems getting his software to run on the hardware that will be used for the upcoming 2007 Gothic Chess Computer World Championship. Finally, this evening, he was able to get it to run. He requested a casual game to be played against SMIRF, which I did do.
The time controls were G/30 + 15 seconds per move.
I will post the complete game here tomorrow for everyone to review.
My comments on the game:
Both programs showed similar evaluations and Principal Variations for much of the opening. Castling did not appear in the P.V. for quite some time as each program moved their pieces around the board. Both were reaching roughly the same search depths, with neither really outsearching the other.
There was some odd form of "Archbishop chasing Queen" where I thought some of the moves were unusual. Martillo finished a pawn ahead as a result of the run-around. As each program moved progressively faster, it seems that Martillo was able to search 1- and 2-ply deeper, until its score grew. SMIRF's score fluctuated +/- 0.4 pawns through all of this, thinking it was +0.4 one moment, down to +0.2, then to -0.1, back up to +0.1, and back and forth, finally down -0.4
Meanwhile Martillo showed about +2.3 or better, growing to +4.3 at one point. Yet, the score never increased for Martillo, and never got worse for SMIRF. Move after move, +4 for Martillo, about -0.8 for SMIRF at that point.
Finally, towards the end, Martillo picked up the material and checkmated on move 63.
