10.Nxd4
[10.Nxe5
Nxb3
11.cxb3
isn't what White should head for, and shows the point of Black's first playing 8...a5.]

10...exd4
11.Re1N
[11.Qf3
Be6
occurred in a couple of earlier games, and might be better than Karjakin's choice.]

11...Ra6!!
This is a brilliant idea, a la Drimer's rook in the Budapest Defense. Black wants to swing the rook to g6, where it will help in a kingside attack, and that's just what happens in the game. (Note that this wouldn't make much sense if Black's bishop had already been forced to e6.) White's next move makes sense, but we should figure out what's wrong with the obvious 12.Bxd5 Qxd5 13.Rxe7.

12.Qh5
[12.Bxd5
Qxd5
13.Rxe7

And now we look at four moves. Two are clearly bad, one is interesting but leaves White struggling to prove equality, and one is a quick draw. 14.f3

The queen on h5 takes care of ...Bxh3 business, so Black now switches to diagonal #2.

14...b6
Not incidentally also protecting the pawn on a5.

15.Qf3
Taking care of that diagonal too.

15...Be6
This looks like a concession, as it allows White to give Black an ugly, backward pawn. The dynamic factor of the f-file is even more importnant, though.

Another small shocker! The e-pawn isn't backward anymore, but Black is just surrendering the d4 pawn.

is safer. Black has some advantage after 19...e5
