Stockfish 16CPU v Komodo Dragon 16CPU (LTC Gambits Match)

[Graham Banks]

GAME 69

Komodo Dragon regained the gambit pawn, but was behind in development and had a more passive position.
After the engines had castled on opposite sides, Komodo Dragon was the first to start attacking, with 18...b5, which sparked off some brief fireworks.
As a result, Stockfish was a pawn up, and Komodo Dragon had reduced forces with which to attack.
When black played 39...b4, Stockfish was able to counter with 40. h5, which forced the queens to come off, and put an end to any further attacking ambitions that Komodo Dragon may have had.
In the rook, minor piece and pawns endgame, Stockfish still had the extra pawn, but both engines were already evaluating the position as 0.00.
Stockfish returned the extra pawn, focusing on trying to create problems with its passer on the queenside, but after the minor pieces were exchanged, it was clear that the game was going to be drawn.

[Graham Banks]

GAME 70

In the return game, Stockfish was first to vary, with 9...c5.
Komodo Dragon then chose to complete its piece development, and both engines castled on the kingside.
Stockfish gradually assumed the role of aggressor, with its knight on d4 proving to be a nuisance.
Stockfish took aim at the white king with 36...g4, but already, both engines were spitting out 0.00.
Despite that, the following passage of play looked very cut-throat, with Stockfish saccing a piece in its king hunt.
However, Komodo Dragon always had the draw in its sights, which it wisely took with a perpetual check.

[Graham Banks]

Slav Gambit

1.d4 d5 2.c4 c6 3.Nf3 Nf6 4.Nc3 dxc 5.e4 *

White tries to go ahead without bothering to regain his pawn playing a4 first to prevent b5. He rather wants to get active in the center. This gambit is unclear and seldom played in top level chess.

[Graham Banks]

GAME 71

Interestingly, both engines were already evaluating the position as 0.00 after move 8!
Stockfish responded to the mass of black forces on the queenside, by countering in the centre, forcing Komodo Dragon to castle long.
For Stockfish, that was like showing a red rag to a bull, and it immediately attacked on the queenside, saccing a piece with 19. Bxb5, and conceding the exchange shortly afterwards.
Funnily enough though, all Stockfish had after all that action, was a draw by perpetual check.

GAME 72

Komodo Dragon was the first to change course in the return game, immediately attacking the queenside pawn mass with 9. a4.
11...c3 initiated some sharp play, with Komodo Dragon giving up its queen for two knights, but with two dangerous connected passers behind enemy lines.
After the dust settled with 19...Kd7, both engines were already screaming out that the position was 0.00 though.
Stockfish eventually sacced the exchange on the kingside in order to have a passed h-pawn, in addition to its passed a-pawn,
When Komodo Dragon captured the a7 pawn after it was offered, Stockfish infiltrated on the queenside to harass the king.
However, the black b-pawn had now become unstoppable, so Stockfish took the perpetual check that was available.

Ponziani Counter-Gambit

1. e4 e5 2. Nf3 Nc6 3. c3 f5 *

Ponziani's countergambit 3...f5!? was successfully played in the grandmaster game Hikaru Nakamura–Julio Becerra Rivero, US Championship 2007. Magnus Carlsen used it for a victory in 2013.

[Graham Banks]

GAME 73

After Stockfish took the gambit pawn, Komodo Dragon was able to get it back at the cost of losing castling rights. The queens also came off in the process.
There didn't appear to be any cause for concern for black, as both sides were able to complete development, without any hiccups.
After 30 moves, the rooks were all traded off down the e-file, leaving us with an endgame in which each side had three minor pieces, and five pawns on symmetrical files.
Following further exchanges, there was a locked up position, in which neither side could make any progress.

GAME 74

Stockfish varied first in the return game, with 8...Nce7.
Komodo Dragon then offered a pawn to initiate action directed against black's uncastled king, culminating in winning the exchange.
The game then took another twist, with Stockfish giving up a minor piece in return for a 3 on 1 pawn majority on the queenside.
Interestingly, both engines already evaluated this endgame at 0.00, and further play confirmed the draw.

[Graham Banks]

Reti Gambit (Anti-French)

1. e4 e6 2. b3 d5 3. Bb2 *

The Reti Gambit - White gives up the e4 pawn for rapid development on the queen side of the board and the ability to keep the board wide open. As white playing e4, the French Defense is something many players don’t want to see and this opening gives white multiple variations to continue the aggressive nature of an e4 opening while thwarting many of the ideas a typical French Defense player has. If black tries to hold onto the pawn they will generally find themselves with a weakened pawn structure heading into the end game while not being able to actually hold onto the material advantage. If black lets white easily retake the pawn on e4 then white can castle on either side of the board while having a huge lead in development.

[Graham Banks]

Game 75

Komodo Dragon opted not to take the pawn offered, and both sides went about completing their development.
It looked initially as though black might be considering a sac on the kingside, but instead preferred to build pressure there, with pawn advances as part of the plan.
However, Stockfish had things covered, and created counterplay on the queenside as a distraction.
Although both sides had evaluated the game at 0.00 since move 30, Stockfish had a nice way to ensure that there would be no surprise nasties, by trading its queen for Dragon Komodo's only rook and only minor piece.
That left Komodo Dragon with its queen and pawns against Stockfish's rook, bishop and pawns, and once the remaining queenside pawns came off, there was no way for either side to make further progress.
