A Position That Confuses Many Chess Engines

[smirobth]

Here is the other position
[d]8/4n1k1/8/6PK/4p2P/3B4/8/8 w - - 0 0

"Deep Fritz 10, running with 3 cores active under Boot Camp on my quad-core 2.66Ghz Xeon Intel Mac Pro desktop computer. DF10 has 1024MB hash, *no* EGTs, and default settings otherwise. This first screenshot is not a “cold start”---I had been analyzing lines with hash preserved for over a day---but the phenomenon does show when the program is started up directly in this position, which is known to be drawn."

"Deep Fritz is saying that taking the pawn by 74.Bxe4 will eventually put White 7.49 points ahead, which would happen only if it sees that White can make a Queen and win, since a Queen is valued at 9 points. But that the position after 74.Bxe4 is indeed drawn by the reply …Ne5 is shown by the online server of perfect play for 6 or fewer pieces maintained by Knowledge for IT in Germany."

If it is drawn, then none of the engines I tried can see it. One even predicts a checkmate.

As noted in earlier posts, the position of the knight is incorrect; it should be on f7, not e7. With the knight on e7 Black is indeed lost.
