Re: test position, Komodo - Deep Fritz 12
This is a pretty cool one Jon, and I instantly saw a winning endgame after
1.Bxf6+ Kxf6 2.Re5 Qe7 (or 2...Kf7) 3.Rexe6 Qxe6 4.Rxe6+ Kxe6 (this simplification is decisive)
Unfortunately computers don't think like us humans in these kind of positions
Here is what Stockfish 1.6.3 JA thought of it (Although it finds the key move and a path to victory it doesn't take the simplest path).

Re: test position, Komodo - Deep Fritz 12
this is what's interesting...for whatever reason computers (or at least shredder, which im testing now) don't see this. shredder has only considered Bxf6 Kxf6 Re5 Qe7, but sees no win at d26.1.Bxf6+ Kxf6 2.Re5 Qe7 (or 2...Kf7) 3.Rexe6 Qxe6 4.Rxe6+ Kxe6 (this simplification is decisive)

Re: test position, Komodo - Deep Fritz 12
I'd say its definitely not Shredder-specific, a lot of engines opt for something else in that position.its having a lot of trouble. is this a shredder-specific bug or are there other engines who can't easily find a path from this position?
Back to the original position with Firebird 1.1 it chooses 1.Bxf6, however on its 3rd move it opts for the silly 3.Kg2
instead of simplifying to a won king + pawns endgame.New game, Blitz:16'

Re: test position, Komodo - Deep Fritz 12
will any engine play Rexe6? and what i meant about shredder wasn't so much that it couldn't find, that move, but that it found no winning path at all in the time i gave it. at least rybka, FB, & stockfish correctly evaluate the position as winning.
again, the position of interest [d]8/1p2q3/2pRpkpp/p1P1R3/P4PP1/8/7P/6K1 w - - 0 3
komodo, which supposedly has little-to-no endgame knowledge, finds a nice, quick win in a few seconds --

Re: test position, Komodo - Deep Fritz 12
Jon,
I hope you are happy with Arasan's performance in this tournament so far!
As for the game you selected, it's an excellent position and I must say I
was really surprised to see Deep Fritz 12 go down so quickly in this game.
It almost seems as if many engines struggle with this position, for some
reason. At least DF 12 had no clue what was going on at a point.
