Bd6 $1 $11 {puts more influence on the e4 square from the black rook, making it harder for White to play e4 in the future.}) 12. g4 $2 { White clearly wants to castle queenside and attack on the g-file.

Bxe4 $2 {This makes White's position significantly worse. He allows Black to occupy e4 with a cramping pawn that blocks the White queen off from any attack white was hoping to cook up on the kingside. It is now dangerous for White to castle on either side.} (14.

He is still winning, but it would have been much tougher had White played correctly.} (27... Qf6 $1 $19 {threatens Qxf2 and Rc2ch.}) 28. Qb3 $4 {The final blunder. Now Daniel swiftly decides matters by utilizing the pin on the white.} (28. Rg8+ $1 Kxh7 29. R8g5 $1 Rc2+ 30. Qxc2 Rxc2+ 31. Kb3 Qxg5 32.
