I have to go out but quickly here (Black to play)
You have got a reversed Rossolimo v The Sicilian (3.Bb5) a tempo
up, here an annoying move is 3.Na4 with a3 and b4 ideas.
Play it like a Sicilian reversed (a6 is always a handy and often
good move in the Sicilian. You get in a3 with tempo) .
Just a quick idea, not seen the whole game.
