You are right, blitz is not very meaningful for this test. I intended to deeply
analyze these positions at home, and only then play them against chess engines.
But I could not resist, and I played the first position with white against
crafty.
Please note that crafty was playing without tablebases, and that I only gave it
one processor, instead of the usual two (I forgot it). Anyway, crafty lost
without giving much of a fight. I do not say I can save the same position
against crafty, but definitely I can offer a lot more resistance.
Time control was 40 moves in five minutes. Next time I will play with a longer
time control, and I will give crafty two processors.
José.
