Komodo 8CPU v Stockfish 8CPU Rematch (latest versions)

[Graham Banks]

GAME 32 - the opening promised much with castling on opposite sides. However the queens came off early, followed by the minor pieces. The eventual rook and pawns endgame had some interest, but neither side ever felt that it had any advantage. Another draw as the suspense continues!

[Graham Banks]

GAME 33 - Stockfish completed a remarkable comeback from 5-3 down to take the rematch by 6 wins to 5. In this decisive game, both sides tried to achieve something on the kingside without success. However, Stockfish managed to put what seemed to be an unbreakable pin on one of Komodo's rooks before switching its attention to the queenside, winning material and subsequently the resulting queen and pawns ending.

So!! Total games 78. Komodo win 11, loss 10, Draw 57, Elo difference= +4 which is negligible . . Conclusion Equal elo!!

Best regards,
