[D] r3k2r/1q1nbp1p/p2pp1p1/1p2P3/1P1NN3/P6Q/2P3PP/4RR1K w - - 0 1 In the epd-database from ChestUCI I found this position. It is supposed to be a mate in 14 but I believe it to be a mate in 13. Can anyone check this? With help from CM10K I get: 1.Txf7 Kd8 [1...Kxf7 2.Dxe6+ Ke8 3.Pxd6+ Kd8 4.Pxb7+ Kc8 5.Dc6+ Kb8 6.Dxd7 Ta7 7.Pc6+ Ka8 8.Pxa7 Tf8 9.Pa5 Tb8 10.Pc8 Lc5 11.Dc6+ Tb7 12.Dxb7#; 1...Dd5 2.Txe7+ Kd8 (2...Kxe7 3.Dh4+ Ke8 4.Pxd6+ Kf8 5.Tf1+ Kg7 6.Tf7+ Kg8 7.De7 Dxe5 8.Tf1 Dxh2+ 9.Kxh2 Pe5 10.Pxe6 Pg4+ 11.Kg1 a5 12.Dg7#) 3.Txd7+ Kxd7 4.Pf6+ Kc8 5.Pxd5 Kb7 6.Dxe6 Tac8 7.Dd7+ Kb8 8.Dxd6+ Ka7 9.Db6+ Ka8 10.Pe6 Txc2 11.Pec7+ Txc7 12.Pxc7#] 2.exd6 Kc8 [2...Dd5 3.Pxe6+ Kc8 4.Txe7 Kb8 5.Pf8 Pxf8 6.Dc3 Dc4 7.Pc5 Pd7 8.Dxh8+ Ka7 9.Txd7+ Kb6 10.Tb7+ Kc6 11.Tc7+ Kxd6 12.De5#] 3.Dc3+ Kb8 4.Pc6+ Dxc6 5.Dxc6 Ta7 6.Pc5 Pxc5 7.dxe7 Pd7 8.Txe6 Te8 9.Tf8 Pf6 10.Txe8+ Pxe8 11.Dxe8+ Kc7 12.Dd8+ Kb7 13.Tb6# Frank
