This position, after 23.Ne4 is very instructive. Enrique seems to be right that
programs that do not spot the mate threat in this position tend to fall prey to
fast finders. I've had enough time to check on several progs -- the successful
ones (fast finders) took only a couple of seconds at the most to spot both the
threat and the mate: Crafty 17.6 SMP, Fritz 6 (all test versions), Deep Junior
6, Hiarcs 7.32... I haven't set up my Tiger 12, but am sure that it would spot
the mate in a split second :) Programs that had a hunch something was wrong
with capturing on a2: Genius 6.5, Zarkov 5.1, Wchess 1.2a (none of these saw
the coming mate quickly, but assigned a hefty bonus to White after capturing).
I was pretty upset to find out that Rebel Century could not at least "intuit"
about the coming threat to his King via the check on c8 and the subsequent
checking on g5 with a quick mate. Has anyone tried the previous Rebels?
