Round 4 [Comments by Kim Qvistorff]

1.e4 c5 The Sicilian Defense.
2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 e5 # 6.Nf5
[6.Ndb5 is the right move, going into the Sveshnikov variation. 6...d6 7.Bg5 a6 8.Na3 b5 9.Bxf6 (or 9.Nd5 Be7)
9...gxf6 10.Nd5]
6...Bb4 All of a sudden Nf5 looks great!
[6...d5 is much better.]
7.Nxg7+ Kf8 8.Nf5
[8.Bh6 is a winning game for White!]
8...d5 right move.
[8...Nxe4 does not work because of 9.Qg4!]
9.Bh6+ Still an excellent move. White is still better.
9...Ke8 10.Ng7+ Ke7 11.exd5
[11.Bg5 better.]
11...Nxd5 12.Bg5+ f6 13.Bh4 Now the world comes tumbling the other way... [White needs to play 13.Bd2]
13...Nxc3 14.Qxd8+ Rxd8 15.Nh5
[15.bxc3 Bxc3+ 16.Ke2 Bxa1]
15...Ne4+ 16.Ke2
[16.c3 is the only option.]
16...Bg4+ 17.f3 Bxh5 18.g4 Rd2+ 19.Ke3 Nd6
[19...Bc5+ 20.Kxe4 Bg6# checkmate!]
20.gxh5 Can you now find the checkmate in 3 moves?
20...Nf5+ 21.Ke4 Rd4+ 22.Kxf5 Rf4#
0-1
