[Event "TCEC Cup 8 Bronze Playoff"] [Site "https://tcec-chess.com"] [Date "2021.03.02"] [Round "1.4"] [White "KomodoDragon 2671.00"] [Black "AllieStein v0.8-120f959_PS1.4"] [Result "1-0"] [Annotator "Kaufman,Larry"] [PlyCount "121"] [EventDate "2021.??.??"] 1. d4 Nf6 {Black is a super-strong neural net engine. Komodo won the match by winning this game after drawing the first three. Note that although the selected opening favors White, Komodo also had to defend the Black side of it, which it did successfully.} 2. c4 c5 3. d5 e5 4. Nc3 d6 5. e4 Nbd7 6. Nf3 g6 7.

Instead Dragon sacrifices the pawn to eliminate the key defender of the king, the bishop, and thereby to get a long term initiative against the weakened king and kingside pawns.} Ncxd5 23.
