>[D]3k4/2p5/1pKp4/p2P4/2P5/P7/1P6/8 w - - bm c5; id "J&S45.10"; c0 "This one is
>questionable.";
This last one is funny. To me, at first, it looks drawn. Then, when you think
about c5, it seems unstoppable. But when I look at crafty's decision that c5 is
a draw and follow the pv given, it looks drawish. I think that probably, this
last one is a draw. I don't have much hope for Kb7 to actually accomplish
anything.
Crafty's look at this final position:
