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

GAME 66

Stockfish was first to vary from the previous game, with 9...Qd8.
Komodo Dragon's compensation for its two pawn deficit, was quicker development, plus an active and threatening looking position.
After some exact defensive play, Stockfish was able to castle on the queenside, still with the two extra pawns.
But 35. b4 was a clever move from Komodo Dragon, winning the exchange, although the queens also came off.
However, both sides saw the position as dead drawn, and indeed, a draw was the result.

Queens Gambit - Chigorin Defense

1. d4 d5 2. c4 Nc6 *

The Chigorin Defense violates several classical principles: Black does not maintain the center pawn at d5, the c-pawn is blocked, and Black must be willing to trade a bishop for a knight. In return, Black gets quick development and piece pressure on the center. Although opening assessments change as improvements are found for each side, the Chigorin is generally considered playable for Black, and it is useful as a surprise weapon against the Queen's Gambit. Alexander Morozevich is perhaps the only modern grandmaster who regularly plays the Chigorin Defense; however, in the 1980s, Vasily Smyslov did employ the opening against Garry Kasparov, achieving a draw.

GAME 67

Whilst not a gambit in the truest sense of the word, still an interesting reply to the Queens Gambit.
Out of the opening phase, Komodo Dragon ended up with a rather troublesome knight posted in the heart of white's position.
Stockfish was able to rid itself of the pesky knight, but in the series of exchanges involved, an endgame eventuated, in which each side had two rooks, a knight and five pawns.
It was interesting endgame though, and included Stockfish giving up knight for three pawns, but both sides evaluated it as 0.00, and the game was eventually drawn.

GAME 68

With 4. e3, Komodo Dragon took the return game on a different course.
However, both sides completed development without any hurdles, and then mass exchanges took us into a late middlegame with queens, rooks and seven pawns each.
Komodo Dragon lined up pressure down the semi-open c-file on the backward c6 pawn, but this was easily defended by Stockfish.
Both sides began shuffling pieces, making the occasional pawn move, and when exchanges eventually occurred, they did nothing to alter the expected draw.

Queens Gambit - Winawer Counter Gambit

1.d4 d5 2.c4 c6 3.Nc3 e5 *

The Winawer Countergambit ( l.d4 d5 2. c4 c6 3.Nc3 e5 !?) was dismissed by theory until quite recently, when it enjoyed a considerable renaissance in the 1990s.

The Winawer Countergambit challenges White's center and he must choose to accept or decline. If he declines he usually does this in one of two ways. Either the conservative 4.e3 where you can get a comfortable game as Black. Or 4.cxd5 which ends up as an open version of the Accepted Line after 4...cxd5 5.dxe5 Nc6.
The most common response from White is to simply accept the gambit at the first time of asking (4.dxe5). Now you will play 4...d4 kicking the Knight and this pawn becomes the focal point of your operations.
5.Ne4 is often played and you can recover the pawn with 5...Qa5+ 6.Bd2 Qxe5. Your d4-pawn controls important squares in White's camp, c3 and e3. This makes it difficult for him to develop as he would wish.

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.

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.

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.

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.

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.

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.

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.

GAME 76

Whereas Komodo Dragon had played 3...a6, Stockfish played 3...Nc6, and although a6 was played on the next move, the game was already taking on a different complexion, with Komodo Dragon eventually castling kingside, and Stockfish castling queenside.
Komodo Dragon was first to create action, opening up the c-file to exert pressure with both rooks, then saccing the exchange to gain control of the h1-a8 diagonal.
But as usual, Stockfish had the situation covered, and when the queenside became locked up, there was nothing further that either side could achieve.
The game concluded with a threefold repetition.

French Defense - Korchnoi Gambit

1.e4 e6 2.d4 d5 3.Nd2 Nf6 4.e5 Nfd7 5.Bd3 c5 6.c3 Nc6 7.Ngf3!? *

The line is filled with tactical opportunities.
White offers a pawn to divert the black e-pawn. If Black accepts the gambit, White has two main plans. The first is to play d4 and Bxf4, regaining the gambit pawn with central domination. The alternative plan is to play Nf3 and Bc4 followed by 0-0, when the semi-open f-file created after a pawn push to g3 allows White to attack the weakest point in Black's position, the pawn on f7. Theory has shown that, in order to maintain the gambit pawn, Black may well be forced to weaken the kingside with moves such as ...g5 or odd piece placement (e.g. ...Nf6–h5). A downside to the King's Gambit is that it weakens White's king's position, exposing it to the latent threat of ...Qh4+ (or ...Be7–h4+). With a black pawn on f4, White cannot usually respond to the check with g3, but if the king is forced to move then it also loses the right to castle.

GAME 77

Komodo Dragon eventually accepted the gambit pawn, prompting Stockfish to eye up the black kingside.
After its light squared bishop was traded, Stockfish decided that there was nothing to be gained on the kingside, so traded queens to take control of the open d-file.
However, the remaining black bishop blocked everything off nicely by going to d5, and with neither engine being able to find a way to make progress, pieces were just shuffled around until ChessGUI draw adjudication settings ended the game.

GAME 78

As black, Stockfish was uninterested in winning a pawn on d4, preferring to exchange a few minor pieces and safely complete development.
Both sides castled kingside, and so it was the queenside on which the action was now focused.
Once the queenside pawns were liquidated, we were left with a late middlegame/endgame. in which each side had queen, rook, knight and five pawns (symmetrical files).
Although Komodo Dragon then infiltrated the queenside with its queen and rook, there was nothing to be gained, and once the rooks were exchanged, a draw quickly followed.

And so, last, but not least, we present the Kings Gambit.

1. e4 e5 2. f4 *

White offers a pawn to divert the black e-pawn. If Black accepts the gambit, White has two main plans. The first is to play d4 and Bxf4, regaining the gambit pawn with central domination. The alternative plan is to play Nf3 and Bc4 followed by 0-0, when the semi-open f-file created after a pawn push to g3 allows White to attack the weakest point in Black's position, the pawn on f7. Theory has shown that, in order to maintain the gambit pawn, Black may well be forced to weaken the kingside with moves such as ...g5 or odd piece placement (e.g. ...Nf6–h5). A downside to the King's Gambit is that it weakens White's king's position, exposing it to the latent threat of ...Qh4+ (or ...Be7–h4+). With a black pawn on f4, White cannot usually respond to the check with g3, but if the king is forced to move then it also loses the right to castle.

https://en.wikipedia.org/wiki/King%27s_Gambit

GAME 79

After Komodo Dragon had accepted the gambit pawn, Stockfish went for the 3. Nf3 route.
Komodo Dragon played 4...h6, and followed up by traipsing a knight onto g3, to inconvenience the rook on h1.
In the following moves, Stockfish captured the pawn on f4, but immediately gave up the pawn on e4 to open up lines against the enemy king. The position after 11...Nf6 looks a little harrowing for Komodo Dragon, although the white rook on h2 seems to be awkwardly placed.
Despite that, both sides were able to castle queenside and complete their development, with solid positions.
In fact, after Komodo Dragon had plonked a knight on c4, neither side wanted to do anything to break the equilibrium, and after much piece shuffling, draw adjudication ended the game.

GAME 80

As white, Komodo Dragon played 4. d4 rather than 4. Bc4, and when Stockfish played 4...g5, immediately challenged that with 5. g3.
The situation on the kingside became quite interesting during the following moves, but both sides were able to castle queenside, and Stockfish swapped off queens, perhaps thinking that it might improve the chances of getting something out of its extra pawn.
However, Komodo Dragon was able to recoup the pawn after ganging up along the f-file, and the exchanges that occurred during that process led to an endgame where each side had rook, minor piece and four pawns, with the pawns all being on the queenside.
Neither engine could really make progress though, and so the match ended with a whimper, rather than a bang.
