My match with Dennis was actually quite exciting, and so I have annotated it lightly:
1.e4 c5 2.Nc3 Nc6 3.f4 g6 4.Nf3 Bg7 5.Bb5 Nd4
One of the main "book" moves. The idea is to prevent the exchange on c6, which would weaken black's pawns.
6.0–0 Nxb5 7.Nxb5 a6 8.Nc3 b5 9.a4 b4 10.Ne2 Bb7 11.d3 d6
A flexible move. 11. ...c4 or 11. ...Rc8 or even 11. ...e6 were worth consideration.
12.c3 Nf6 13.Ng3
A move I had been waiting for. I already had the following idea in mind a few moves ago:
13...h5 !?
The point is to pry open the light square diagonal, if allowed. Also, black is trying to avoid castling short, as white may have a typical attack with f5 and a queen transfer to the kingside via e1. Now it is black who will attack on the kingside, and the game takes on a very sharp nature.
14.Re1
[14.h3 Was worth considering, with the plan of preventing a black pawn from reaching h3. 14...h4 (14...Nd7) 15.Ne2 Nd7 16.Qb3]
14...h4 15.Nf1 h3 16.g3
Now black has g2 and h1... nice spots for a queen.
16...Qb6 17.e5 dxe5 18.fxe5 Nd5 19.c4 Nc7 20.Ne3 0–0–0 21.a5
Pushing the queen to the perfect square.
21...Qc6 22.Rf1
Now, I missed a nice opportunity. Can you find it?
22...Rh5 was the move played, but...
[22...Bxe5 !! instead, was much better. Can you see all the variations if white takes the piece? 23.Nxe5 Qh1+ 24.Kf2 Qxh2+ 25.Ke1 (25.Ng2 Qxg2+ 26.Ke3) 25...Qxg3+ 26.Kd2 Qxe5 And h2 is coming.]
23.Kf2 Bxe5 24.g4
A nice shot, which I missed. Fortunately, I have plenty of compensation after ...
24...Qxf3+ 25.Qxf3 Bxf3 26.Kxf3
[26.gxh5 Bxh5 27.Rh1 Rxd3 Black has plenty of compensation for the exchange.]
26...Rhh8 27.Rf2 Rd4
[27...Rxd3 Not this move! Now white wins a piece: 28.Ke4 with a fork.]
28.Bd2 Rf4+ 29.Ke2 Rxf2+ 30.Kxf2 Bxh2
The rest of the game finished in time pressure. 31.Rh1 Be5 32.g5 Bxb2 33.Ng4 Ne6 34.Be3 Bd4 35.Bxd4 Nxd4 36.Nh6 f6 37.Rxh3 fxg5 38.Kg2 Ne6 And whites flag fell. 0-1
