Subject: Fritz 6 Endgame Weirdness

Author: Len Eisner

In the following endgame position, Fritz 6 plays f7??  I know this is the
tablebase at work but it seems strange to me.  And after …a2, Fritz 6 plays
Kg2?? which also look weird.  Then after Black queens the pawn with a1-Q, Fritz
6 goes out of the table base and plays f8=q which is only good for a draw
according the Thompson database on the Fritz 5 CD. If I had the Nalimov QPvsQ
tablebase, Fritz 6 would have played g8=q and won.  But that table base does not
come with the program.

I created this position to test the table base.  It did not arise in an actual
game.
