Black to move and win ?? Yes !!

[D]8/5p2/1kp5/p1p5/P1PpKPPp/1P5P/8/8 b

The above position was derived from a real skittles game I had. I was Black and
the King was on g7 and the f-pawn was on f6 as shown below:

[D]8/6k1/2p2p2/p1p5/P1PpKPPp/1P5P/8/8 b

White had just blundered with King from d3 to e4 1.Ke4??...From that position
the win for Black is quite easy. White made it very easy for Black with:
1.Ke4 f5+!!2.gf Kf6 3.Kf3 Kxf5 4.Kf2 Kxf4 and Black wins easily. The King cannot
take the f5 pawn because the Black d pawn will promote. If the White King
retreats to f3, ...fxg4+ wins, because ...Kc7 and Black gets to the queening
square in time, and Black's d pawn always threatens to advance. And lastly, if
white's h-pawn takes on g4 then Black will have a passed h4 pawn and a passed d3
pawn, and the White King cannot stop both.
 I was so fascinated with that position, that I wanted to see just how far away
the Black King could be and still secure the win. The position is very
deceiving. It appears at first that the Black King is out of the game and should
lose or at least draw. But winning for Black ?? I showed this position to quite
a few masters, and all did not realize that Black is winning. I even showed this
position to Grandmaster Lev Alburt at the US Amateur Team East, 2 years ago, and
he did not realize it either. Nor did GM Arthur Bisguier.

The same motifs apply to the first position above. See how your programs
evaluate this position. Some find it easily and some take much longer.
The winning line results in both sides Queening. That is the analysis of Fritz8.
Actually, Fritz 8 has White Queening first, but Black Queen' immediately after
that with extra pawns that win.
Enjoy

Happy New Year !!
