I entered a problem contest in Israel when the target was to compose long studies with a known kind of final positions. in one of the cases the target was to compose a problem when white does mate with only king and one minor piece(knight, bishop or pawn) and I composed the mate in 17.5 as a result. These problems were not composed by me They are part of the ssdf games The evaluation of Fritz5.32 show more than 5.5 pawns advantage and I am sure Fritz5.32 is winning and the question is only to find mates. Junior5.3 show mate in 10 in the first position after looking 57466 Knodes (8 minutes and 35 seconds) main line 1.g4 g5 2.Rxb5 e5 3.Rxe5 a3 4.bxa3 d3 5.Rxg5 Rc8 6.Rg7 Rc2+ 7.Ke3 Re2+ 8.Kd4 Re4+ 9.Kxe4 d2 10.Rg8# position 2:Rh1 is mate in 6(Junior5.3 191Knodes at depth 9) position 3:Rh3 is mate in 7(Junior5.3 26911Knodes at depth 15 after 2 minutes and 49 seconds) position 4:Qf4+ is mate in 8(Junior5.3 47102Knodes at depth 16 after 5 minutes) position 5:Junior5.3 sees dxe3+ as mate in at most 11 moves after 29 minutes and 25 seconds(394201 knodes) I think that chessmaster saw shorter mate but I am not sure 1...dxe3+ 2.Ke2 Qf4 3.d4 Qxg4+ 4.Kd3 e2+ 5.Kc4 exd1Q 6.Rxd1 Qxd1 7.c3 Qd3+ 8.Kd5 Qb5+ 9.Ke4 Qe2+ 10.Kd5 Rxc3 with mate next move. position 6:Junior5.3 saw after more than an hour that Be3+ is mate in 12 Uri
