(This is what sometimes happens when I analyze a game in my head. Most of the time, this is not problem. But this time I thought he had played 8…Ng4, and 9.e6 works well in that variation.

By the way, after 8…Nh5, 9.Qf3 is considered the best move here. A few games illustrate the possibilities.

Now let’s get back to the original game.)

**9…fxe6! **(Oops! Black definitely has the advantage.)** 10.Qf3 **(Trying to keep Black from castling.)** 10…d5! **(Another good move. This bolsters his pawn structure.)** 11.Bb3 **(Forced. White wants to keep the bishop on the diagonal.)** 11…Bg7 12.Bg5 Nf6? **(Black could have tried 12.Rf8, and forgo castling to use the open “f” file.)** 13.O-O-O O-O!?** [Seems safe. But White’s bishop is still on the diagonal. If Black’s plan is king safety (always important), then he probably should hide his king on h8.]** 14.Qg3 c5? **(Again, …Kh8 is called for. All this move does is loosen his pawn structure. Perhaps he wanted to push …c4, getting rid of the bishop. But this approach is too slow.)** 15.Rhe1 **(White’s development is now superior, for the cost of a pawn. His bishop is about to become very active.)** 16…Bd7? 16.Bxf6! **(The start of a combination to open lines against the enemy king.)** 16…exf6**

**17.Nxd5! Kh8** [Now he moves his king to safer square. But he loses a critical tempo in the process. By the way, taking the knight leads to immediate disaster. I’ll let the reader figure it out the moves (it’s more fun that way!)]** 18.Nc7 +- Qe7 19.Nxa8 Rxa8 20.Qc7 Rd8 21.Rxe6 Bh6+ 22.Kb1 Bxe6 23.Rxd8+ 1-0**
