Having just finished an article on 1.b4 for Australian Correspondence Chess Quarterly, I've come to the conclusion I'm not a big fan of the opening. Possibly it is because it is one of the few off-beat openings I haven't tried, but to me White just doesn't get enough out of it. Staking a claim on the queenside is a little premature, given that the centre is yet to be contested.
However it does have its devotees so here is a game where White manages to grab more than a fair share of the centre by gambiting two pawns and quickly crushing Black.
