The British Knockout championship is taking place now as a warm-up to the London Chess Classic that starts this Friday. There have been very interesting games (especially the ones played by Nicholas Pert) like this one between Jonathan Rowson and Gawain Jones.

[fen "5rk1/4R3/1pQp4/3Pp3/4B1pp/4q1P1/PP3rPK/3R4 w - - 0 1"]

Gawain had a huge advantage but has just played ...h4 letting it slip away. Rowson has one chance to avoid losing the game. What should he play?

  • Rg7+ follows by never ending check with the White's queen? – SmallChess Dec 4 '15 at 4:00

The tags seem to give a big hint . . .

1 Rg7+! Kxg7 (Kh8 can't be better, since White can at least repeat with 2 Rh7+ Kg8 3 Rg7+) 2 Qd7+ Rf1-f7 (Rf8-f7 3 Qxg4+ and perpetual check since White has access also to c8; K-moves get mated: Kf6? 3 Qe6+ and 4 Qg6, or Kh6/g8/h8? 3 Qh7+) 3 Qxg4+ Kh8 4 Qxh4+ Kg8 and White can either take the perpetual starting 5 Qg4+ (checks from h3/g4/e6/c8) or go for more with 5 Rf1!?

1. Rg7+!! if 1 .. Kh8 2. Rh7+ Kg8 3. Rg7+ etc if 1 .. Kxg7 2. Qd7+ followed by perpetual check from the white queen on the white squares (e6 & g4).
