On what processor running at what speed?
If you forget to mention it, then you'd better not mention any time...
The current version of Chess Tiger running on my laptop PII-233MHz (48Mb hash)
changes its mind for R5a7 in 957 seconds. But it has a fail low much earlier, in
90 seconds, so it would need 90s to see the problem and to decide to extend its
thinking time in search of a better move.
957s on my computer must be something like 148 seconds on an Athlon 1.5GHz
(correct me if I'm wrong).
90s on my laptop is like 14 seconds on an Athlon 1.5GHz.
An Athlon 1.5GHz is approximately as fast as the P4-2.2GHz used in the game.
So I believe that the new Chess Tiger would not blunder in the same position...
I think the reason why Gambit Tiger 2.0 played the losing Bxa1 is that it failed
to see some deep mate threats. The new Chess Tiger is better in this regard.
