Yes, I did. I also enjoyed this problem:

qnb5/1p1kBK2/pPp5/P1p5/2P5/8/8/8 b - - 0 0

White to move and win. It SHOULD be an easy one, only move#2 and the motive must
be found.
What amazes me is that Crafty and Fritz5.32 with their deepest search depth
don't find the final winning move in move#19 pv. They have only a draw eval so
it must be the best move because the material is way down, or are there other
reasons? It is 19.Be5 which is found by them with 0.00, just facing that move.
If you make 19.(winning move) SUDDENLY they realize the win but not 19.Be5 up to
depth 60!

OK, I add the line much below, if you don't want to see it, you won't...
