[d]7k/8/8/1p6/p5N1/r4p2/1K6/8 b - - 0 51

Black played the strong and simple 51. ... Ra2!! 52. kxa2 and it was over for white as the following position shows.

[d]7k/8/8/1p6/p5N1/5p2/K7/8 b - - 0 52

I studied this just a bit with crafty, nothing involved. Much better than Ra2+ is b4 which is a mate in 15 or less. It likes b4 with a huge score from the beginning and finds a mate in 15 in under 30 seconds. Deeper search might find something somewhat shorter.

The point is the move was humanlike in a spooky sort of way.

what would worry me is that b4 has such a huge eval, Ra2 would have to have an equally huge eval or else the program went for a poor choice. Ra2 will ultimately lead to mate, but given a minute Crafty never saw anything near the eval of b4 after a few seconds...

I checked, there's nothing wrong with the eval. My guess is time, inter alia, may have been the issue and the program had a hiccup so to speak.

This is your area; maybe you can find the cause?
