Rybka and IvanHoe, to name a couple, can't see this is draw:

8/8/7p/p3k3/8/P5KP/8/8 b - - 1 50


Even at this point (Komodo fails here too):
6K1/7P/8/8/1k6/8/8/q7 b - - 0 59

Seeing the actual draw is not so easy. Crafty evaluates either as near zero however. I think about .4 for the first, and .08 for the last one...

But statically evaluating either as a draw is beyond dangerous because you can move a single piece and change the outcome...

computers use endgame tb's now, so it doesn't matter.
