The Chinese GM Zhao Jun emerged as the only player on maximum points going into round five of the Hastings Masters after he had despatched GM Maxime Lagarde in short order.
11.Bf1 is a new move, unambitious-looking, but suggesting that the pawn on e5 gives White a good game.
13…Nc5 provokes a fight, but Black’s position is suspect once the bishop on c6 is exchanged and his kingside remains undeveloped.
Perhaps instead 13…Be7 14.b4 a5 15.b5 Nc3 16.bxc6 Nxd1 17.cxd7+ Rxd7 or 13…Be7 14.b4 a5 15.b5 Nc3 16.Qb3 Bd5 17.Nc4 Ne4 18.Qc2, but Black’s knights look vulnerable.
There was a crazy line: 15…Qxc6 16.b4 Ncd3 17.Re3 Be7 18.g3 Qh1+ 19.Kxh1 Nxf2+ 20.Kg1 Nxd1 21.Re1 Nd5 22.Rxd1 Ne3 23.Bb5+ Kf8 24.Rf1 Nxf1 25.Bxf1, but White is better in the endgame.

Sengupta – Sowray, round four. 40.Rd6 Ra8 41.Ke2 Re8+ 42.Kf2 Ra8 is a draw, but White found advantage. How?
