White does get to queen a pawn, and people might stop there, but Rinck had to work it out with all those queens on the board. 1.a7 Be4 2.d7 Rd2 3.Bd5 Bxd5 4.d8Q Kg6 5.Qd6+ Kf5 6.Qe5+ Kg4 7.f5 b3 8.f6 b2 9.f7 b1Q 10.Qg7+ Kh5 11.a8Q Bxa8 12.f8Q Qg6 12...Qb2 13.Qf5+ Kh4 14.Qfg4# 13.Qe5+ Qg5 14.Qf7+ Kh4 15.Qh7+ Kg4 16.Qe6+ Kf4 17.Qc7+ Kf3 18.Qh3+ Kf2 19.Qf7+ Qf6+ 20.Qxf6+ Bf3 21.Qfxf3+ Ke1 22.Qhf1# and no chess engine for help.
