Sergiy Didukh (Ukraine)
1.g8Q Bf2+ 2.Bd4! Unexpected sacrifice! White discharges bR from a forced capture on the next move.
The obvious plan was to win bB after 2.Kb7? Rxc3 3.Qf7+ Kd6 4.Qxf2 Rb3+ 5.Kc8 Nc3=
2…Bxd4+ 3.Kb7 (wQ is threatening every black piece) 3…Re3! This move saves the rook and lets Black keep his king on e-file if wQ takes the bishop.
3…Rh4 4.Qg5! (quiet attack on R) 4…Bf2 5.Qf5+ Kd6 6.Qxf2+-
3…Ke7 4.Qg5+ Bf6 5.Qc5+ Kf7 6.Qc4+! Ke7 7.Qc7+ Ke6 8.Qc8+-
4.Qc4! Quiet attack on Bishop.
Thematic try (R-sacrifice, fork) 4.Qd5+? Ke7 zz 5.Qxd4 Rb3+ 6.Kc7 Rc3+ 7.Kb6 Rb3+ 8.Kc5 Rc3+ 9.Kd5 Rd3! 10.Qxd3 Nb4+ draw.
4…Ke7 5.Qd5! zz 5…Bb6!
5…Rc3 6.Qe4+! Kf7 7.Qxd4+-
5…Bf6 6.Qc5+ Kf7 7.Qxe3+-
6.Qg5+? Kd6 7.Kxb6 Rb3+ 8.Ka5 Nc3=
Black’s plan works after 7.Qc5+? Kf6 8.Qxe3 Nd5+!= fork.
7…Kd7 8.Ka5!+- Precise quiet move wins material. ‘Quiet Queen’ theme
