Dominguez Perez: a nice little move

I am enjoying playing through the games of the Cuban GM Leinier Dominguez Perez at the Grand Prix I Thessaloniki. With two rounds to to, he is jointly in the lead with Gata Kamsky. He is clearly having the tournament of his life.

The games which are played on workdays I can only flick through after they have finished. I liked his win against Morozevich. In my flick through, I was surprised that Moro resigned after the little move f4, assumed he had had enough, bowing to the inevitable, and I moved on. But, the move f4 nagged me and I decided to have another look. In my flick through, it would not have been obvious to insert f4 gf before playing c7.

The reason for f4 came to me fairly quickly, and made me smile. It will be time to give up chess when it doesn't give smiles. 42 f4 was not attacking, or not mainly attacking, it was actually prophylactic: black intended to meet c7 with Rc1 but now, once the g5 pawn is on f4, Rc1 is prevented by Qf4+ with double attack on the LPDO rook.

Very neat.
