1: Hyatt-Prentos: The Immortal Series
1. e4
2. d5 Nc6
3. Qg4 Qxc8 Qxd8+
4. Kxd8 dxe4 Nf6 h5
Prior to this game, this position was one of some theoretical importance. 2. d5 Nc6 has been played, according to Battista, over 1000 times, with black winning 700+ games. However, the variation is completely unsound for black, as this game proves. The variation black has pinned his hopes upon is Leoncini's 4. Kxd8 dxe4 Nf6 h5. While this series attains a great lead in development for black, and indeed stops the obvious series involving Bxa8, what it fails to do is catch up in material. White, by not trying to take much material himself, and by catching up in development, achieves a winning position.
5. d4 d5 dxc6 Be2 h4 !
I found this novelty well before the first round even ended (back in fall 1998), but this was my first chance to play it in a tournament game. Black is completely blown out of the water by this 5. Everything gets mated or loses materially. This strong novelty should sound the death knell for 4. Kxd8 dxe4 Nf6 h5. The bishop on e2 and the rook on h1 are strong pieces for participating in mates. The dangling pawn on c6 must be captured, forcing black to waste time. In addition, white is up material (2 minor pieces).
6. e6 bxc6 Rb8 Rb3 Rh3 Rxh1
7. b4 b5 bxc6 Nc3 Nd5 Rb1 Rb8#
Not a particularly interesting conclusion, but the game is included for the importance of its novelty.
1. d4
2. d5 Nc6
3. b4 b5 bxc6
This was a popular continuation in the semifinal round. Regardless of its theoretical assessment, the variation is of little importance, as 3. Bf4 Bxc7 Bxd8 and 3. Bg5 Bxe7 Bxd8 are both clearly winning.
4. bxc6 Bf5 Bxc2 Bxd1
5. Nd2 Rb1 Rb8 Rxa8 Rxd8+
6. Kxd8 Bxe2 Bxf1 Bxg2 Bxh1 Nf6
