[%c_effect g8;square;g8;type;Interesting;persistent;true] An interesting move, very much in the style of the creative player with the black pieces, although it had already been tried before, so perhaps it was still preparation. The idea of the move is less about advancing the g-pawn, which we will see later, and more about protecting this pawn so that the knight can move to d5 or e4.

Since the Kramnik vs. Kasparov match, we know that this endgame from the Queen's Gambit Accepted is not as innocent as it seems. In a final round in which it's difficult to weigh how much risk is necessary; there's nothing better than a safe position, but with a chance of playing for victory. 7... f8c5  8. d1d8  8... e8d8  9. c4e2 This bishop move is necessary sooner or later. It frees the c4-square for a knight and the bishop can go to f3 in many lines. 9... d8e7  10. b1d2  10... c8d7  11. d2b3  11... c5b6  12. c1d2  12... b8c6  13. d2c3 So far we are following theory. Although both sides had options, we can say that the moves were natural. The game starts to get more subtle from now on.
