RetiCK - quick reply to a reader suggestion

1.e4 c6 2.b3 d5 3.Bb2 dxe4 4.Ne2 Nd7 5.Ng3 Ngf6 6.Nc3 Nc5 7.Qe2 Bg4 8.Qe3 e6!? Diagram This is a suggestion from a reader of my first post on 2.b3 vs CK.

9.h3 Bf5

A) 10.Nxf5 exf5 11.g4!? f4! (11...Qd7 12.0-0-0 0-0-0 =; 11...fxg4?! 12.hxg4 Nxg4 13.Qe2 Nf6 14.0-0-0 Be7 15.Bh3 Qd6 16.Rde1 +=) 12.Qxf4 Ne6 13.Qg3 (13.Qe3 Bc5 14.Qg3 Bd6) 13...Bd6 14.Qg2 Nf4 15.Qg1 Diagram This is = (0.00) according to my engine, and probably it's right as white can pressure pawn e4 with 0-0-0, Re1, g4-g5 and even f2-f3.

B) 10.d4!? is an interesting alternative. 10...Ncd7 Diagram

Here white has a selection of choices, depending on what level of risk is acceptable for him.  


11.Ncxe4 Nxe4 12.Nxe4 Bxe4 13.Qxe4 Qa5+ 14.c3 Ba3 15.Qc2 Bxb2 16.Qxb2 0-0 17.Be2 =;
11.0-0-0 Nd5 12.Nxd5 cxd5 13.Nxf5 (13.f3) 13...exf5 14.g4;
11.Nxf5 exf5 12.g4.

11...Bd6!? looks critical.

11...Bg6 12.fxe4 Qa5 13.0-0-0 Ba3 (13...Bb4 14.Kb1) 14.Be2 0-0-0 15.h4 h6 16.Bxa3 Qxa3+ 17.Kb1 Nb6 18.Rhf1 =;
11...Nd5 12.Nxd5 cxd5 13.fxe4 Bg6 (13...dxe4 14.0-0-0) 14.0-0-0=

12.Nxf5 exf5 13.fxe4 0-0 Diagram

14.0-0-0 (14.e5? c5!) 14...Nxe4 15.Nxe4 Re8 16.Kb1 Diagram


16...Rxe4 17.Qd2 Nf6 18.Bd3 Rf4?! (18...Re8 19.Bxf5=) 19.d5 cxd5 (19...Nxd5 20.c4!) 20.g3 (20.g4) 20...Rf3 21.g4 Diagram # with initiative.

17.d5 Be5 18.dxc6 bxc6 19.Bc1 Bf6 20.g4 Diagram with good compensation for the pawn according to the machine. Probably based on the bishop pair and a minority pawn storm with g4-g5. But if you're going to play any of this, you should of course check everything for yourself more carefully.

10.d4!? is very interesting indeed. And apologies for not giving my name. But I think black can play better. 14...fxe4, with the idea:
15.Nxe4-Re8 16.Nxf6+-Qxf6! with development adv. Seems risky in an over-the board game, but in corr I would happily play it.

Well, it's certainly one way to play it. 17.Qf3 Qxf3 18.gxf3 could be an ending White would want to explore though - bishop pair and more space, once the c4+d4 duo is established, but Black has resources too, e.g. e6-e5 and a Nd7-f8-g6-f4 manoeuvre.
