Djaja [D]6R1/P2k4/r7/5N1P/r7/p7/7K/8 w - - bm Nh6 This is one of my favorites. White to play and draw. I don't think programs will solve this one within reasonable time in the next few years. It takes a lot of moves to see the perpetual check on the g-file. K.K.Behting [D]8/8/7p/3KNN1k/2p4p/8/3P2p1/8 w - - bm Kc6 Kc6 is the only move that draws. Thought to be unsolvable for computers but Patzer by Roland Pfister solved it about a year ago. After 16 ply in 0:06:49 Patzer finds Kc6 with score -0.04 (Computerschaak 2001 vol.6). Computers will hold a draw if you give them the first move. Hans.
