[D] 2r3k1/7p/q3pBp1/1p1pPnP1/p1nP4/P1N4R/1PQ5/7K w - - 0 1

A nice game between Pharaon 2.62 - TheKing3.23 (p4 2.47ghz, game in 25).  Here
Pharaon played Rxh7 which seems to draw.

The game continued:

1. Rxh7 Kxh7 2.Qh2+ Kg8 3.Qh8+ Kf7 4.Qh7+ Ke8 5.Qxg6+ Kf8 6.Qh7 Nxe5 7.Bxe5 b4

[D] 2r2k2/7Q/q3p3/3pBnP1/pp1P4/P1N5/1P6/7K w - - 0 8

I think this was the critical position.  White still seems to have a draw, but
Pharaon blundered by playing Qh8+ (time trouble) and the king was able to escape
and win.  Most of the programs I've tested likes 8. g6(TheKing3.23 expected g6
giving a draw score), and black is the one that gives perpetual with ..Qf1+ Kh2,
Qf2+ etc..

So what does your program say about these two positions?
