Diagram #Some interesting opening play now unfolds, but it has been seen before recently in this very magazine. So I have the luxury of simply copying my notes from Gao-Hague NZ Champs 2018 in the January issue verbatim for the next several moves. Copying BEGINs>

Playing this here is a rather neat transpositional trick, that has been played by So, Nakamura and others. It's much more common to play the move when Black has played ...d6 rather than ...O-O on their last move. Then it comes with tempo against f7 allowing time for f4 ahead of ...h6 (which is the goal - White wants to play f2-f4 over the top of the Knight on f3 but unfortunately the rules don't allow that in one move).

7...h6 8.f4!
The trick is that White has time for this even in this move order

[8...hxg5? 9.fxg5 sees Black getting destroyed on the Kingside. The details are left as an exercise for the reader]

9.Nf3 d6 10.Bxf4
We have transposed to, for example Kramnik-Leko Linares 2003 which reached the same position by a more conventional route after 1.e4 c5 2.Nf3 Nc6 3.Nc3 e5 4.Bc4 d6 5.d3 Be7 6.O-O Nf6 7.Ng5 O-O 8.f4 exf4 9.Bxf4 h6 10.Nf3

10...Bg4 This reasonable looking move is a near novelty. ......Be6 instead has been played literally hundreds of times. <Copying END Oh whoops, I need to wake up - this time Ben does play ...Be6 instead of ...Bg4

11.Nd5 Nb4
[11...Bxd5 is much more popular, but if I leave my computer to think for a while it prefers ...Nb4, which has been played a couple of times by Sveshnikov. I suspect Ben does his homework]

12.Nxf6+ Bxf6 13.Bxe6 fxe6 14.c3 Nc6 15.Bg3 d5 16.Qb3 b6 17.e5 Bg5 18.Qa4 Rc8 19.Qg4 Rf5 20.d4 cxd4 21.cxd4

[21...Nb4! Is very strong according to the computer - the knight is getting very mischievous and might be going to d3 or e3 (via c2) or even picking up a pawn on the weird route a2-c1-e2]

22.Nxg5 Rxg5 23.Qd1
Black might be slightly better with a better minor piece, but the position quickly burns out to nothing

23...Ne7 24.Bh4 Rf5 25.Bxe7 Rxf1+ 26.Qxf1 Qxe7 27.Rc1 Rxc1 28.Qxc1 Qb4 29.Qc8+ Kh7 30.Qc2+ Kg8 31.Qc8+ Kh7 32.Qc2+ Kg8 33.Qc8+ 1/2-1/2
