Hi Tanya,

Thanks for posting this position.
Hard time for IsiChess to find f6 (>10 minutes).
After a closer look, i found an static eval bug in this PV-position.
In pawn-endings "King in square" implementation should be rather accurate.
Mine was not, even i had implemented the accurate routines already, with the
result of a huge black winning bonus.

[D]8/7p/2pp1p2/4k3/P7/8/6K1/8 w - -

Regards,
Gerd
