ShashChess Dev v Stockfish 12 (8CPU match with LTC)

[Graham Banks]

GAME 10

Of course, it's easy enough panning an opening line as bad for black, but could ShashChess also win from the white side?

In short, the answer was no.
Stockfish (black) set up a strong defensive position, and the best that ShashChess could do was to win a couple of pawns at the expense of entering an opposite coloured bishops situation.
Although the queens and a pair of rooks were also still on the board, black's position was solid, and both sides could see that it was drawn from that point on.

GAME 11

Next up were a pair of King's Indian Saemisch games.

Saccing a pawn with 14.e5 was an interesting decision by Stockfish, and led to the queenside and centre being taken out of the equation.
The next step was to advance the kingside pawns, but ShashChess was able to defuse any serious attacking prospects by exchanging queens.
Although Stockfish came out two pawns down, it had enough compensation with its c and d passers to have both sides seeing the position as equal.
Stockfish won its two pawns back, and we were left an interesting endgame in which white had four passers on the queenside and black a group of four pawns on the kingside.
To the human eye, it probably looked as though white's pawns were more dangerous, but the engines demonstrated that it was an easy draw.

GAME 12

The reverse game took a different direction, with Stockfish (black) getting in f5 and possible chances on the kingside.
But Shashchess was up to the challenge, and Stockfish never really threatened, with both sides assessing the position as equal.
After mass exchanges, a drawish endgame was reached.

GAME 13

In a 3...Qd6 Scandinavian, the best that Stockfish can do, with white, is to wreck black's kingside pawn structure with 21. Bxf6.
However, ShashChess has no problems holding the endgame. A bit of a sterile draw.

GAME 14

ShashChess opts to play the opening differently, and when Stockfish plays 12.g4 with both kings still uncastled, the game promises to be interesting.
Both sides castle queenside, and when the kingside becomes locked up, play switches to the queenside.
However, there proves to be no danger to either king, and eventually pieces get traded off to leave a drawn endgame.

A Scotch line is easily handled by both sides and an early endgame results.
The game is evaluated as dead equal after move 17, and a quick conclusion occurs with a three fold repetition.

GAME 16

Stockfish varies immediately with 9....a5.
ShashChess is happy to give up the c4 pawn, and proceeds to castle queenside.
Stockfish castles kingside, and the position looks like it could get tricky for either side.
Ironically though, both engines evaluate the position as 0.00.
A material imbalance occurs when Stockfish trades queen + bishop for two rooks + pawns to gain a small edge.
However, the white pieces coordinate too well to allow any tangible advantage to develop, and the game plays out to another draw.

GAME 17

In a King's Indian line, Stockfish gives up one pawn, and then a second (20.f5) to stir things up on the kingside.
However, there is no advantage to be gained, so Stockfish regains the pawns and goes into a drawn double rooks endgame.

GAME 18

The game promises to be interesting when Shashchess is allowed a semi-open h-file against the Stockfish king.
But Stockfish mixes things up on the queenside to the extent that ShashChess must also castle kingside.
After that, mass exchanges occur and a drawn rook and pawns ending is reached by move 31.

So with 6 games left in the match, Stocfish leads by +2 -0 =16.

GAME 19

In a Dutch Leningrad line, both sides feel that white has the edge.
ShashChess blocks the kingside and centre, but after a pawn exchange, Stockfish takes control of the open c-file, lining up both rooks on it.
However, ShashChess counters by opening up the a-file and making its own rook intrusion to gain equality.
Eventually Stockfish gets both rooks on the 7th rank and takes the perpetual.
