I don't understand the motif off this move, it seems that white will playing Nxf5 anyway so i think the bishop is better stay at g7.

Compare this diagram and the previous diagram. Surely you would say Jones have ruin his position but i think the most accurate explanation is as Steve Giddins report in the official website about of one of UK players performance in the 2nd round ..."as the pressure of making a move every 30 seconds proved too much. Once again, her Chinese opponent deserves great credit for her tenacious defence, but even so, it was all too painful to watch. At one point, I feel sure I felt an earth tremor, caused by Akiba Rubinstein revolving in his grave, at the thought of what these FIDE dunderheads (to coin a phrase) have done to the endgame!..."
