1.d4 Nf6 2.c4 g6 3.Nc3 Bg7 4.e4 d6 5.Nf3 O-O 6.Be2 e5 7.O-O Nc6 8.d5 Ne7 9.b4 {The Bayonet.} 9...a5 10.Ba3 axb4 11.Bxb4 b6 12.a4 Re8 13.Re1 
    ( 13.Qd3 Nf5 14.a5 bxa5 15.Rxa5 
        ( 15.Bxa5!? Ba6 16.exf5 e4 17.Nxe4 Nxe4 18.fxg6 hxg6 {Almost all of black's pieces are well placed ensuring some compensation for the pawn.} )
        ( 15...Rb8 16.Nb5 Nd4 17.Nfxd4 exd4 18.f3 {I don't see the prospects black has in this position. Having good control of a number of dark squares means black is not in any immediate trouble though.} )
        ( 16.Rxa8 Qxa8 17.exf5 e4 18.Nxe4 Nxe4 19.fxg6 hxg6 20.Qc2 c6!? 21.Bd3 cxd5 22.cxd5 Qxd5 23.Bxe4 Rxe4 24.Bxd6 Bg4 25.Rd1 Qf5 26.Qb3 Bxf3 27.gxf3 Rd4 {Looks hard won for white.} )
    16...e4 17.Qd1 exf3!? 18.Bxf3 Bxf5 19.Nb5 Qd7 20.h3 h5 21.Rxa8 Rxa8 22.Re1 Nh7 23.Qd2 Qd8 {There are still some things to watch out for in the position, yet black should be OK.} )
13...Bf8 14.g3!? {This is the continuation I like most, mainly because it prepares f2-f4.} 
    ( 14.Bd3 Nd7!? 
        ( 14...c5 15.Ba3 Bh6 {Can be played yet again.} )
    15.Bf1 Nb8!? 16.Nb5 Na6 17.Bc3 Nc5 18.a5 Qd7 19.Nd2 Ba6 20.Nb3 f5 {Black has set up reasonably and should not be much worse.} )
    ( 14.Bf1 c5 
        ( 14...Nd7 15.a5! c5 16.dxc6 Nxc6 17.Bxd6 {Should be better for white.} )
    15.Ba3 Bh6 {And I'm not sure why f1 is a good square for the bishop.} )
    ( 14.Nd2 Nd7!? 
        ( 14...Bh6 15.Nb3 Nd7 16.a5 Nc5 17.Qc2 {And the tense queenside should favour white.} )
        ( 14...c5 15.Ba3 {Is another possibility of course.} )
    15.Nb3 Nc5 16.Nxc5 
        ( 16.a5 Bd7 {And it is not obvious how white will make further impact on black's position.} )
    16...bxc5 17.Ba3 {I don't think the passed a-pawn is a factor.} )
    ( 14.h3 c5 
        ( 14...Nd7 15.a5 Nc5 16.axb6 Rxa1 17.Qxa1 cxb6 18.Qa7 f5 19.Bxc5 bxc5 20.Rb1 {White invades on the queenside and shoud be somewhat better.} )
    15.Ba3 Bh6 {I don't think white having played h3 impacts much on the position.} )
14...c5 15.Ba3 Bh6 {Black again uses this solid setup.} 
    ( 15...Bg7 16.Bc1 {Does not look overly joyous for black despite him having the plan of preapring f5.} )
16.Bc1 {If I were white I would play this and shortly thereafter try to get in something like Nh4 and f4. For example:} 16...Bxc1 17.Qxc1 Bg4 18.Nh4 Bxe2 19.Rxe2 Nd7 20.Nb5 Qb8 21.f4 {And white should be better.} *
