Teimur Rajabov remains in the lead after four rounds of play in the Geneva Grand Prix and as many as six players follow him at short distance of half a point behind.

Ian Nepomniachtchi defeated the world’s top female player Hou Yifan. In a popular line of Anti-Berlin Ruy Lopez white “bluffed” with 13.h5 leaving the b2-pawn en prise, but black passed on the offer. Nepomniachtchi disapproved 21…Bxf5, after which white got the structure that he aimed for.

Amassing the heavy pieces against the black king, white finally broke through around the first time control, and shortly after claimed a victory.

Peter Svidler modestly said that he didn’t do much in today’s game and that Michael Adams simply self-destruct. Apparently 16…Qc4 was a serious mistake after which black is losing the d5-pawn almost by force.

Svidler snatched another pawn on h7, but he was also critical of his own play as he allowed unnecessary complications. Nevertheless, white’s position was overwhelming and he converted to full point.

The battle between Salem A.R.Saleh and Richard Rapport was truly spectacular, but nothing less was expected from the two inspired players.

Salem admitted that it is very difficult to prepare for Rapport, but he was pleased with the resulting position in the Sicilian defence. After 12.f4, and particularly 14.e5, the position became very sharp.

The material balance was changing move-by-move, and at some point black was two pieces down while seeking the counterplay. Salem agreed that this was the best practical chance.

White gave one piece back to assume a firm grip on the game, and he proceeded to seal the win at the first time control.

The remaining six games were drawn.
