This line is sometimes known as the Polish Defence, or Polish Deferred to avoid confusion with 1.d4 b5 (seen in the famous Karpov-Miles game via the move order 1...a6) which is more widely known as the Polish Defence. Unlike 1.d4 b5 which is generally regarded as pretty suss, 1.Nf3 Nf6 2.g3 b5 is considered to be sound and has been played by quite a few top GMs over the past 50 years.
I've been curious about this line and played it on a whim on the weekend and won with it (see Tas Open and Lightning thread in Tournament Results). I'm considering doing so again in future since from time to time I get bored of the standard 1.Nf3 Nf6 2.g3 g6 3.Bg2 Bg7 4.0-0 0-0 lines, especially against certain opponents.
Does anyone else here play this line? Does anyone know of any books or surveys that devote substantial theoretical coverage (ideally several pages at least) to it? It has a couple of columns in NCO but not the same as reading explanations, discussion, history etc.
