Some programs can find it within a minute or two in my computer (1800XP+), but Shredder 7 doens't see it after 5 minutes in "infinite analysis". Ruffian 1.05, Hiarcs 9, and Shredder 8. need about a minute, more or less. Fritz 8 finds it in 13 seconds, then it drops it, and comes back to it after a minute, like the others. Some other amateur engines that I've tried seem to find it harder. How long did it take to yours? (was it pondering?) Jaime
