Subject: Computer "Sacrifice" Game Example ArasanX v Tinker

Author: Brian Richardson

Date: 08:33:01 02/16/02


A startling computer "sacrifice" during this game, likely the result
of Tinker's poor book, but ending up in an interesting game, IMHO.

[Round "-"]
[White "ArasanX"]
[Black "Tinker"]

Qxg2+ 26. Kd1
{White resigns} 0-1

Here is the sac:
Tinker played Bxf2 after 50 seconds...

[D] r1bqk2r/pppp1ppp/2n5/1Bb1p3/4n3/2P2N2/PP1PQPPP/RNB2RK1 b kq - 0 6

score was still quite negative (good for white) for many moves,
but things led to

[D} r5k1/p1q2pp1/2p4p/7r/2QN2b1/2P3b1/PP1B2P1/RN3RK1 w - - 0 21

where white played Qd3 (perhaps Rf3 is best here),
and it was downhill from there.
