paul: Cooked by: 1.h3 d5 2.Rh2 Bxh3(ph2) 3.Sxh3(Bc8) Bxh3 4.g4 a5 5.Bg2 Bxg4(pg2) 6.c4 a4 7.b4 e6 8.Bb2 Bxb4(pb2) 9.Sa3 Ra5 10.Qxa4(pa7) Qc8 11.QxKe8(Ke8) (suicide of wQ)b5 12.Sc2 dxc4(pc2) 13.a3 Bxe2(pe2) 14.Ra2 Bxa3(pa2) 15.Kd1 b4. (2010-06-19)
Arnold Beine: Here is something wrong. Either Paul's cook does not work, because 10.Qxa4(Pa7)+ is a check (10...Qc8??) or in the given condition "Rex inclusive" must be added. (2023-07-26)
paul: Right, Arnold. Anyway, the proof game is cooked: 1.a4 e6 2.Sa3 B×a3 3.b4 a5 4.Bb2 a×b4(b2) 5.Ra2 R×a4(a2) 6.e4 Ra5 etc, as in author's solution: 7.Ba6 b×a6(Bf1) 8.B×a6(a7) d5 9.B×c8(bBc8) Bb7 10.c4 Qc8 11.Qc2 d×c4(c2) 12.Se2 B×e4(e2) 13.h3 Bf5 14.Rh2 B×h3(h2) 15.Kd1 B×g2(g2). (2024-03-13)
