Hi Mike, Thanks for the engine. I set it up in Arena and tested it on the 4th move postion: 8/4P3/2B5/8/8/6p1/5kP1/5b1K w - - 0 4 Here's the result: Crafty 19.08 SE WB2 29 MB: 11 00:00 4.17 1. e8=B Ke3 2. Bf7 Kd4 3. Bh5 Ke3 4.

Many endgame study books make the opposite claim and surmise that more endings require "study-like finishes" then what we normally suppose. I like to use engines for all sorts of analysis, not just for games and I would trust them more if they were "good" in all situations, however outlandish, although I do understand the programmers practical bent. I'm something of a purist and dabble in all sorts of studies, mates, games, etc. Yace seems to be one of the select few here. It's odd that your machine sees the right idea fairly quickly and much earlier. Your PC is faster, but mine should get there eventually. I wonder if TBs are making the difference.
