Lately I found this easy-to-solve but elegant little study: [D]8/8/8/8/4k3/1P1p4/1r6/R1N1K3 w Q - To my surprise many modern programs can't find the win despite of 5manTBS only 2ply away! Junior 6 (with 5manTBS) sees only a draw after 45 min on Celeron 500/ 128 Also Shredder 4 and Nimzo 7.32 fail to solve it. It is interesting that the older versions of some of the above programs need only 0 sec (Nimzo99) resp. 10 sec (Junior 5.0). Tiger 12.0e takes also 0 sec. It would be interesting to know how other programs do in this position and even more interesting if someone can suggest a reason for this odd behaviour of some leading programs. Since I don't know if this information is embedded in the EPD: white has still castling rights. Gerhard
