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

[Graham Banks]

Draw number 5 of 80 ?

Depends on whether any of the gambit lines used are shady.

[Graham Banks]

GAME 6

The game developed in a fairly similar manner to the previous one, although through different ways.
White's 18. b4 provoked mass exchanges, leading to a completely drawn endgame in which each side had a rook and bishop (opposite colours), and pawn arrangements that promised nothing.

[Graham Banks]

The Blumenfeld Countergambit

1. d4 Nf6 2. c4 e6 3. Nf3 c5 4. d5 b5 *

Black sacrifices a wing pawn to establish an imposing centre with pawns on c5, d5 and e6. The natural development of the bishops to b7 and d6, combined with the half-open f-file for a rook, tend to facilitate Black's play on the kingside. White, on the other hand, will typically look to counter in the centre by playing e4 at some point, while their additional queenside pawn also offers them some initiative on that side of the board.

GAME 7

As black, Komodo Dragon pretty much followed the pre-game script with its play, although it did offer to go into a Benko, which Stockfish declined.
As expected, the early action was on the queenside, but the nature of the game changed when Stockfish played 17. Nxe6.
Although Komodo Dragon's pawn structure was weakened, possibilities opened up on the kingside for it.
Stockfish opted to exchange queens to defuse possible danger, and an endgame ensued in which material was initially equal, but black's three pawns were all isolated.
Komodo Dragon played the ending actively, even giving up one of its pawns, but a draw was always going to be the outcome.

[pohl4711]

On this high end level of computerchess (top engines, huge hardware), even gambit-openings give just draws.
The only way to play computerchess at this level is using my AntiDraw or UHO openings:

https://www.sp-cc.de/anti-draw-openings.htm
https://www.sp-cc.de/uho_2022.htm

For a match with this high-end conditions, I recommend the 2nd UHO-openings level (eval-interval +120 up to +129). The folder is called:
UHO_2022_+120_+129

A match like this should end with a draw-rate between 50% and 60%.


UHO means:

So the Unbalanced Human Openings contain:

- 100% moves played by humans, only. Both players had at least 2300 Elo. (Taken from MegaBase 2022)
- opening lines played by the stronges players are at the beginning of the pgn/epd-files.
- no manually constructed openings (like my Drawkiller openings)
- no manually added moves to make castling impossible (like my NBSC openings)
- no selection of piece-patterns

Hi Stefan,

thanks for your input.

My main motivation for this match is to provide data for those interested firstly on whether the gambits are sound or not, and secondly to show how these top two engines demonstrate that.

I realize that there are likely to be mainly draws, but to be honest, that has never really bothered me.
I just like to see good chess being played.

Regards,
Graham.

GAME 8

In an interesting development, Komodo Dragon chose to give back the pawn early, possibly with the intention of placing pressure on the black centre while the king was still uncastled.
However, Stockfish was unfazed, shoring up the centre quite nicely, and threatening to counter along the semi-open f-file.
Then Stockfish gave up a pawn in order to advance its d-pawn to the seventh rank, but all that eventually transpired following all of the queenside and central pawns coming off, was a dead even rook and pawns ending, because the 3-2 majority on the kingside wasn't enough to play for a win.

At first glance the Marshall Gambit does not look dangerous for Black, but he has to be rather careful if he is to counter White's ideas successfully.

[dkappe]

On this high end level of computerchess (top engines, huge hardware), even gambit-openings give just draws.
The only way to play computerchess at this level is using my AntiDraw or UHO openings:

I think you mean to say that the only efficient way to test top engines is via unbalanced openings. To call that “play” isn’t accurate. Although these gambit games ended in draws, they have been far more interesting and aesthetically pleasing than a thousand ugly uho wins.

[Graham Banks]

GAME 9

As black, Komodo Dragon decided that safety was the better part of valour, returning the pawn for a solid position, and by move 24, the game was pretty much dead, with a double rook and knight ending and symmetrical pawn structures.
However, after the rooks came off, the resulting knight and pawns ending was interesting for a while, despite the game ending in a draw.
Both sides evaluated this game at 0.00 all the way through.
