Nf3 Nc6 3. d4 exd4 4. Bc4 Nf6 5. e5 Ng4 6. O-O Be7 7. Bf4 $6 { Played almost instantly. A bad move, which was a result of not reviewing my lines. This is not what my notes indicate for White.} (7. Re1 {This is in my file, and though Black scores well in practice White should be slightly better objectively.} d6 {More or less forced, else h3 is strong for White.} (7... O-O $2 8. h3 Nh6 9.

Nxd4 $14 {White has a weakness to play against on the d-file.}) 7... g5 $1 {Computer preparation gives this as the best line for Black.} 8. Bg3 $6 {I spent around 20-30 minutes here checking variations} (8. Bc1 $1 {Is apparently what I should have done, but I calculated a lot of the complications after Bg3 and didn't think it was so bad that I needed to play Bc1. Now h5 doesn't have any point and if Black castles short, g5 is a very loose move.} Ncxe5 9. Nxe5 Nxe5 10. Qxd4) (8. Nxg5 $6 { This leads to a miserable ending.} d5 9. e6 Bxg5 10. Qxg4 Bxe6 11. Bxg5 Bxg4 12. Bxd8 $17) 8... h5 9. Nxd4 $5 {The computer doesn't like it, but there were a lot of potential sacrifices and I liked the nature of the position. Black will be under some practical pressure but up material in many lines.} (9. Nxg5) (9. h3 h4 10. Bh2 Nxh2 11. Kxh2) 9... h4 {The critical variation, where I spent most of my time calculating when I played Bg3.} (9... Ncxe5 {I also considered this move, but at least here my bishop on g3 is never trapped.} 10. Bb3 h4 11. Bxe5 Nxe5 12. Nc3 $36 {Black is up a pawn, but they lack development and their king will not be safe for a long time}) 10. Qxg4 (10.

I thought I had a forced repetition of moves. This was important because I was quite low on time. } (16. Nc3 $13 {Is more logical, bringing in more pieces.
