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

[Graham Banks]

GAME 32

Stockfish varied first with 6...e6.
Komodo Dragon eyed up the black kingside, but Stockfish remained untroubled, eventually castling on move 24, and returning the pawn in the process.
The resulting endgame was quite interesting until the white queenside pawns came off, leaving a drawn game.

Staunton Gambit

1. d4 f5 2. e4 *

White sacrifices a pawn for quick development, hoping to launch an attack against Black's kingside, which has been somewhat weakened by 1...f5. Black can decline the gambit with 2...d6, transposing to the Balogh Defence, but accepting the pawn with 2...fxe4 is considered stronger. Although the Staunton Gambit was once a feared weapon for White, it is rarely played today, since theory has shown how to neutralise it, and White scores only about 50 percent.

GAME 33

Stockfish offered up a second pawn, but Komodo Dragon wisely declined, as the consequences of taking it would have been awful.
In order to defuse some of the danger, Komodo Dragon itself offered up a pawn, and following a short, but exciting melee, Stockfish opted to take an early perpetual check opportunity.

GAME 34

The return game followed similar themes, but with Komodo Dragon playing f3 later, Stockfish developed its queenside knight on d7 rather than c6.
After Komodo Dragon took the luxury of castling long, the black pieces immediately sprung into action, and coupled with the a-pawn's advance, won the exchange for two pawns.
Although this afforded Komodo Dragon the opportunity to counter with its own attack, after 23...Ra5, it was forced to take the perpetual check.
Another exciting short draw.

Scotch Gambit

1. e4 e5 2. Nf3 Nc6 3. d4 exd4 4. Bc4 *

Rather than recapturing the pawn on d4, white uses his fourth move to develop a bishop actively and take aim at the f7 square! This can cause the Scotch Gambit to be an exciting opening full of tactical chances for white to exploit.

Black’s two main moves against the Scotch Gambit are 4…Nf6 (attacking white’s e4 pawn) and 4…Bc5 (reinforcing the d4-pawn).

https://chesspathways.com/scotch-gambit/

Instead of 4.Nxd4, White has two ways to offer a gambit. The Scotch Gambit (which is the line recommended by GM Lev Alburt in his book Chess Openings for White, Explained) starts with 4.Bc4. Black can transpose into the Two Knights Defense with 4...Nf6 or he can continue the Scotch with 4...Bc5 5.c3 and now 5...Nf6 will transpose into a safe variation of the Giuoco Piano. Black can instead accept the gambit with 5...dxc3 but this is riskier because White will gain a lead in development, after 6. Bxf7+ Kxf7 7. Qd5+ and Qxc5.

The black response 4...Bb4+ to the Scotch Gambit is called the London Defense.

GAME 35

In electing to get its king safely out of the centre with 6. O-O, Stockfish offered Komodo Dragon a second pawn, which was politely declined.
When Komodo Dragon responded to 7. e5 with the clever counter-thrust 7...d5, the resulting flurry of exchanges took most of the sting out of what had been a sharp position.
This resulted in an ending in which each side had two rooks, a bishop (opposite colours) and five pawns apiece, but once all of the rooks had come off, the draw was inevitable.

GAME 36

The return game followed the same path until Komodo Dragon varied with 11. Bg5.
However, although the resulting tactics gave white the opportunity to win the exchange, it also allowed Stockfish the opportunity to take a perpetual check.

Italian Gambit

1. e4 e5 2. Nf3 Nc6 3. Bc4 Bc5 4. d4 *

It is often played as an alternative to the quiet and closed lines of the Giuoco Piano or Giuoco Pianissimo openings. Black can:
- take with the pawn (4...exd4, a transposition to the Scotch Gambit, usually leading to the Max Lange Attack);
- take with the knight (4...Nxd4), which is considered weak since it allows 5.Nxe5, attacking f7 with the bishop and knight; or
- take with the bishop (4...Bxd4), which is considered best.

GAME 37

After both sides opted for quick development, Stockfish then spiced things up a little with the Re4-Rh4 manoeuvre.
However, there was no real threat there, and once Komodo Dragon played 17...d3, the queens came off, leading to a quiet position with equal material.
With 27...d5, Komodo Dragon gained a spatial advantage, but Stockfish was solid.
After much shuffling around, Komodo Dragon tried again, with 59...b5 and 65...Bxa3, but as before, Stockfish was able to hold a passive position, and the game played out to an eventual draw.

[Graham Banks]

GAME 38

Stockfish was the first to vary from the previous game, with 7...Qh6.
Both sides were able to complete development smoothly, and material was now equal.
Without anything too exciting happening in the process, the pieces started coming off the board, until at move 36, we had an endgame where each side had a knight and five pawns, with the pawns being on symmetrical files.
The inevitable draw resulted with Komodo Dragon giving up its knight to infiltrate the black kingside and pick off the remaining pawns.
