and after White's 81.h4 !!
[D]6k1/8/4pP1R/6p1/3K2PP/8/8/7r b
Check out this Stunning but Simple Rook and Pawns endgame move by Fritz 8.
81.Rh4... !!
It played the move and then gave a completely winning evaluation.
80...Re1-h1 was Black's last move. Fritz thinks Black had a better try in either
80...Rg1 or 80...Kf7 with approx. + 0.50 to + 0.69. The move actually played was
an out and out Blunder. I do not know if the opponent was a program or a human
or Both.
I am using Fritz 8 on a AMD Athlon 2600+ XP with 1 Gig of DDR SDRAM. I had the
Hash tables set at 512. I also have the complete set of 3,4 and 5 piece endgame
tablebases.
Here is the entire game score for those interested.
[Event "Blitz:5'+15""]
[Site "Eatontown"]
[Date "2003.05.30"]
[Round "?"]
[White "Fritz 8"]
[Black "?"]
[Result "1-0"]
[ECO "E12"]
[PlyCount "171"]
[TimeControl "300+15"] (or 5 minutes plus 15 second increments rather)

This game could possibly have been drawn if Black did not play 80...Rh1.
All opinions welcome
