[Strange opening for a player like Mamedyarov. This is not played on the top level for obvious reasons. Black position is clearly highly volatile.] 14. a3!

[This move was undoubtedly a surprise for Mamedyarov. The idea of the move is to open room for king before doubling of rooks on b-file.]  click for larger view19. ...g4?

================
Strange opening for Mamedyarov (why would such a player play Advance Caro-Kann ?) and then after 19. g4? boxing himself into a play without any countergame. Truly strange. I know Nakamura should be praised for potent attack here but I am more of a opinion that this is simply a poor and uncharacteristic play by Mamedyarov. |
