Here's a game I played about five years ago against a master in a local tourney. The time control was Game/90 minutes. I just added some light comments.
1.e4 c5 2.Nf3 e6 3.Nc3 I'm not sure why I like to play this move before d4, there's no independent significance that I can think of a64.d4 cxd4 5.Nxd4
Sicilian - Kan Variation
5...b5 6.Bd3 b4!?
Rare move, Black hasn't developed a single piece yet... I guess my opponent specializes in this because he played the same line against me a few months later. Standard is 6...Qb6 or 6...Bb7
7.Nce2 Nb1 is another option, to keep e2 open for the Queen while still using the c3 idea Bb7 8.0-0 When I faced him again I deviated with 8.c3. I'm not sure why but most likely I just forgot the move order. That game ended in a draw. Qc7 9.c3 bxc3 10.Nxc3 Nf6 11.Be3 Nc6 12.Rc1 Lining up on the open file against the Black queen
Black is trying to mix things up on the kingside. I guess he doesn't plan on castling?
13.h3 Prevents Ng4 and h4-h3 ideas. Now I don't really have to worry about the kingside and can concentrate on getting to Black's king in the center h4 14.Re1 Getting the last piece into the game before the onslaught begins Be7
Opening up lines for my pieces
This is a typical sacrifice in the open sicilian and it seems especially dangerous now
16...Qd6 Black, understandably, doesn't want to open the file against his king. 16...exd5 17.exd5 Bxe1 18.Qxe1 and White will have lots of threats 17.Bf4 e5 18.Nf5 Qf8 19.Bd2 Bd6 20.Nb6 Rb8 21.Be3 Bb4
Ignoring the attack on the rook and placing the bishop on a more dangerous diagonal. Now if Black takes the rook then Nd6+ is unpleasant
22..g6? A decisive error, better was Nd8 trying to defend everything
Black probably missed this move. White is threatening to take the knight and mate on d7. Now the game is over because Black is forced to part with a lot of material
23...Bc8 24.Bxf6 Rxb6? Black sacrifices his queen but his king is still in big danger, maybe he should've tried gxf5 25.Ng7+ Qxg7 26.Bxg7 Rh7 27.Bf6 Bxe1
Simply threatening to take on c6 and invade with the queen
Ba5 29.Bxc6 Rxc6 30.Rxc6 dxc6
31.Qd6 Now it's a forced mate
