In this game Black plays an unusual opening. White grabs control of the center, but misses a chance to win a piece. Just as soon as Black gets a good position, he captures a pawn with the wrong piece on his twelfth turn and White immediately takes advantage, winning a piece. Thereafter White exploits his advantage with utmost energy, culminating in a decisive checkmating attack. He had a safer play, offering the queen trade, but his king took care of itself. 1.d4 Nc6 2.e4 Nf6 Black moves out both knights without pawn support. The knights are unstable and run into trouble. Both 2...e5 and 2...d5 return the game to a normal situation. 3.e5 Nd5 4.c4 Nb6 5.Nc3 [5.d5 Nxe5 6.c5 wins a piece.] 5...d5 [5...d6 is better forcing the exchange of center pawns and breaking up the white domination.] 6.c5 Nc4 7.b3 N4a5 8.g3 Bf5 9.a3 Be4 [9...e6 is safer.] 10.Nxe4 dxe4 11.Ne2 This move allows a strong counter. 11.b4 tries to win a piece, but ...Qxd4 12.Qxd4 Nxd4 threatens a fork on c2. Better is 11.Be3, blocking the e4 pawn, which will come under attack. Qd5! 12.Be3 White blocks the e4 pawn before it advances with a discovered attack on the h1 rook. Nxb3? Black captures with wrong piece. Now White leaves the black knight stranded with no defense by attacking Blacks centralized queen. [Correct is 12...Qxb3 13.Qxb3 Nxb3] 13.Nf4 Qd8 14.Qxb3 Na5 15.Qc2 15.Qa4+ forks king and knight. If 15...Nc6 16.d5 wins the pinned piece. 15...f5 16.exf6 gxf6 17.Qxe4 Qd7 18.Bg2 Qb5 19.Kd1!?
