The concrete example to back this up is the position before that one I posted.
Black played ...Qc3-e5, allowing me to at least pick up the b-pawn.  Crafty
flips a lot between ...Qe5 and ...h6.  As I write this, it's on depth 14, and
...Qe5 is preferred.  Even the main line after ...h6 has ...Qe5 being played on
Black's next move, so Crafty would lose this position in practice.  But moves
like ...h6 and ...Kf7 don't drop anything, and White still has his work cut out
for him to win this ending (before a bad ...Qe5.)  I would play it out for sure,
but I don't even know if it is a theoretical win.
