[%c_effect g5;square;g5;type;Mistake;persistent;true] This plan is incorrect and is the main reason for Black's defeat. The position becomes very difficult to defend. It's a bit strange to play like this, considering that White has the supremacy of the dark squares and the king becomes a target on the a1-h8 diagonal.
1. e2e4  1... e7e5  2. g1f3  2... b8c6  3. f1c4  3... g8f6  4. d2d3  4... f8c5  5. b1c3 This Italian Opening with the knight on c3 was played a few days ago by Rapport. Adams had already played it a few times. Many different plans are possible in this opening and this is one of its attractions. 5... h7h6  6. e1g1  6... e8g8  7. h2h3  7... d7d6 I don't like this move very much, as it allows White to exchange the knight for the bishop, giving sense to the play with Nc3. 8. c3a4 [%c_effect a4;square;a4;type;GreatFind;persistent;true] 8... c5b6  9. a2a3 A necessary move to open the way for the bishop and not allow a similar maneuver for Black with ...Na5. The exchange on b6 does not need to be done now, as the bishop has nowhere to run. In chess it's good to be flexible. 9... c8e6 Other moves were tried recently: 10. c4e6  10... f7e6  11. c2c3  11... d8e8  12. b2b4  12... c6e7  13. a1a2 [%c_effect a2;square;a2;type;GreatFind;persistent;true] This plan has become traditional in the Italian, especially after an exchange of bishops on e6. The rook is very useful on the second rank, defending White's king and also putting pressure in the opposite position, going to c2 or d2. 13... g8h8 A new move. Tabatabaei has a dubious plan in mind. 14. f1e1
