This position arose in a game I played at Mechanic's Institute in San Francisco last week: [FEN "6k1/8/P3P3/1p4P1/1b6/5R2/r7/7K b - - 0 1"] The programs I have at home all want to play 1...Rxa6 here, which only draws after 2. Rb3 Ra4 3. g6. But the winning move is 1...Bd6! The main variation runs 2. Rf7 Rxa6 3. Rd7 Bc5! 4. Rd5 Rc6 5. Re5 Kf8, and now white has a choice of 6. Rf5+, 6. g6, or 6. e7+, but all variations eventually lead to lost rook and pawn endgames. 6. Rf5+ Ke7 7. g6 Kxe6 8. Rg5 Rc8 9. g7 Kf7; 6. g6 b4 7. g7+ Kxg7 8. e7 Bxe7 9. Rxe7 Kf6; or 6. e7+ Ke8 7. g6 b4 8. Rg5 Bd4 9. g7 Bxg7 10. Rxg7 Rb6. I am curious if any programs solve this, especially the ones with tablebases.... Oh, and this is all home analysis, so feel free to poke holes in it. If anyone can find a draw for white after 1...Bd6!, please let me know. Bela Evans, USCF 2218
