GAME 16
Komodo Dragon was the first to vary from the previous game, with 21. Bf4, but we still ended up with white having 4 pawns for the sacrificed piece.
Both sides believed white had a small edge, but once the rooks came off, and the black bishop had the pawn chain under control, they tended to think it was pretty much equal.
Although not being forced to do so, Stockfish sacced its knight for two pawns in order to get the queens off and take the game into a bishops with opposite colours endgame.
The game was adjudicated as drawn not long afterwards.

Re: Stockfish 16CPU v Komodo Dragon 16CPU (LTC Gambits Match)
Queens Gambit
1. d4 d5 2. c4 *
The move 2. c4 helps white fight for a space advantage in the center, which is a key component of the Opening Principles.
Of course, the pawn does seem to be undefended…but let’s examine what happens if black accepts this pawn sacrifice with 2…dxc4
Black is temporarily up a pawn, but their control of the center will be greatly reduced. Now or later, white may play e4 and obtain full central control.
Black’s c4 pawn is rather weak. After white moves the e-pawn, white’s light-squared bishop will be eyeing this pawn, and it will be difficult for black to stay a pawn-up in the long run without making significant concessions.
Because of these factors, black often declines the Queen’s Gambit – and the white c-pawn is allowed to remain standing proudly on c4, exerting pressure on the center.

White can get back the pawn after 1.d4 d5 2.c4 dxc4 when the simplest way that is not the best is 3.Qa4+

Re: Stockfish 16CPU v Komodo Dragon 16CPU (LTC Gambits Match)
GAME 17
Komodo Dragon declined taking the c-pawn, whereupon Stockfish shortly afterwards decided to exchange on d5.
It was interesting that Komodo Dragon chose to develop its bishop on a more active diagonal (6...Bf5) at the expense of allowing its kingside pawn structure to be compromised, although the queens did come off in the process. No long term harm done though, as the pawn structure was restored when Stockfish exchanged bishops on g6.
Komodo Dragon tried to create some action on the queenside, but Stockfish was happy to keep things closed up. As a consequence, there was a long period of piece shuffling before the draw adjudication settings put an end to our suffering.

Komodo Dragon declined taking the c-pawn, whereupon Stockfish shortly afterwards decided to exchange on d5.
It was interesting that Komodo Dragon chose to develop its bishop on a more active diagonal (6...Bf5) at the expense of allowing its kingside pawn structure to be compromised, although the queens did come off in the process. No long term harm done though, as the pawn structure was restored when Stockfish exchanged bishops on g6.
Komodo Dragon tried to create some action on the queenside, but Stockfish was happy to keep things closed up. As a consequence, there was a long period of piece shuffling before the draw adjudication settings put an end to our suffering.

Re: Stockfish 16CPU v Komodo Dragon 16CPU (LTC Gambits Match)
GAME 18
The return game developed in a more classical manner, although I was surprised when Komodo Dragon chose to castle on the queenside.
Castling on opposite sides was like showing a red rag to a bull, and Stockfish immediately starting throwing its queenside pawns forward.
However, with 14. a4, Komodo Dragon stymied the attack somewhat, until Stockfish muddied the waters with 21...Nxe4.
I can't give adequate explanation of the complexity and depth of the sharp middlegame that followed, but it was pretty amazing stuff.
To cut a long story short, we emerged into a Q + two minor pieces and pawns. The danger to both kings had gone, and Komodo Dragon had an extra pawn, while Stockfish had the bishop pair.
The queens came off, followed by the white knight and a black bishop. But both sides had evaluated the game at 0.00 since move 19, and the inevitable draw resulted.

The return game developed in a more classical manner, although I was surprised when Komodo Dragon chose to castle on the queenside.
Castling on opposite sides was like showing a red rag to a bull, and Stockfish immediately starting throwing its queenside pawns forward.
However, with 14. a4, Komodo Dragon stymied the attack somewhat, until Stockfish muddied the waters with 21...Nxe4.
I can't give adequate explanation of the complexity and depth of the sharp middlegame that followed, but it was pretty amazing stuff.
To cut a long story short, we emerged into a Q + two minor pieces and pawns. The danger to both kings had gone, and Komodo Dragon had an extra pawn, while Stockfish had the bishop pair.
The queens came off, followed by the white knight and a black bishop. But both sides had evaluated the game at 0.00 since move 19, and the inevitable draw resulted.

Re: Stockfish 16CPU v Komodo Dragon 16CPU (LTC Gambits Match)
It's interesting they both chose the Re1, d3 plan rather than the old mainline of d4. The Marshall used to be fairly venomous, but apparently nowadays, it's seen as drawish. As Levon Aronian put it, "I play the Marshall when I don't mind a draw, and the Berlin when I want to win."Graham Banks wrote: ↑Sat Jun 11, 2022 1:30 am GAME 14
With reversed colours, the two engines followed exactly the same path as in the previous game, up until 23...h5.

Re: Stockfish 16CPU v Komodo Dragon 16CPU (LTC Gambits Match)
GAME 19
With Komodo Dragon having taken the gambit pawn, Stockfish immediately set its sights on the weakened black kingside, with an early h4-h5.
Komodo Dragon returned the pawn in order to complete trouble-free development, and we saw a situation with castling on opposite sides.
Stockfish surrendered its a-pawn so that it could take the black d-pawn, but the position looked pretty much equal.
Then the queens came off, and we entered an endgame where each side had a rook, bishop (opposite colours) and 5 pawns.
Some interesting play led to Stockfish having a passed h-pawn, but Komodo Dragon was threatening to create its own on the queenside, with its king in support.
But the position had been considered as 0.00 by both sides since the queens had come off, and the ChessGUI draw adjudication settings kicked in to end the game.

1/2-1/2[/pgn]
With Komodo Dragon having taken the gambit pawn, Stockfish immediately set its sights on the weakened black kingside, with an early h4-h5.
Komodo Dragon returned the pawn in order to complete trouble-free development, and we saw a situation with castling on opposite sides.
Stockfish surrendered its a-pawn so that it could take the black d-pawn, but the position looked pretty much equal.
Then the queens came off, and we entered an endgame where each side had a rook, bishop (opposite colours) and 5 pawns.
Some interesting play led to Stockfish having a passed h-pawn, but Komodo Dragon was threatening to create its own on the queenside, with its king in support.
But the position had been considered as 0.00 by both sides since the queens had come off, and the ChessGUI draw adjudication settings kicked in to end the game.
