Hi Leonid! Mine finds a Mate in 7 in 0 seconds at ply 6: 00:00 BM7 06 1... Bc3+ 2. Rxc3 Nf3+ 3. Ke2 Rd2+ 4. Kf1 Rd1+ 5. Kg2 Rg1+ 6. Kh3 Bf5+ 7. g4 Bxg4x I guess these are too easy for 'usual' chessprograms nowadays ... although they are always beautiful for the human eye. I just remembered the following position from the Hoogovens Tournament in my country in 1995. It was a game between Cifuentes and Zviaginsev, and black surprised everyone with a beautiful (series of) sacrifice(s). For me this is one of the nicest games I've ever seen. Here it is: [D]3rr1k1/1b1q1p1p/p2b1npB/2pP4/1p2n3/4N1P1/PPQ1NPBP/R2R2K1 b - - The game proceeded like this: 1... Nxf2 2. Kxf2 Rxe3 3. Bxe3 Ng4+ 4. Kf3 Nxh2+ 5. Kf2 Ng4+ 6. Kf3 Qe6 7. Bf4 Re8 8. Qc4 Qe3+ 9. Bxe3 Rxe3+ 10. Kxg4 Bc8+ 11. Kg5 h6+ 12. Kxh6 Re5 0-1 Now, I don't think Nxf2 results in a mate in X with X<20 :) But you could try various positions working from the end of the line backwards. So for example: [D]4r1k1/1b3p1p/p2bq1p1/2pP4/1pQ2Bn1/5KP1/PP2N1B1/R2R4 b - - is a mate in 6. Take one more move back and you get this: [D]3r2k1/1b3p1p/p2bq1p1/2pP4/1p3Bn1/5KP1/PPQ1N1B1/R2R4 b - - is a mate in <=9, I think. I was just now trying this position: [D]3r2k1/1b1q1p1p/p2b2p1/2pP4/1p4n1/4BKP1/PPQ1N1B1/R2R4 b - - This is after taking another move back, but I haven't found a mate yet. Well, I did my best ... hope you like this, my friend! Greetings from Amsterdam, Paul
