So, okay, I know that modern quads are faster than my old octal, but I still like the odd 8CPU match anyway, especially at longish time controls.

Developmental (unreleased) version of ShashChess v Stockfish 12.

Time control is 2 hours with 30 second increments.

24 games.

Live broadcast in my 16084 port of TLCV.

I'll post finished games here as I'm able.

It's not TCEC, but some of you might still be interested.

GAME 1

In a Polish opening, ShashChess eyes up the kingside, and following a redeployment of pieces, advances with h5 and g4.
The pawn sac on g4 looks dangerous for white, but Stockfish counters on the queenside, and with careful defense, all ShashChess has is a perpetual.
A nice game all-round.

GAME 2

As black, Stockfish centres early attention on the queenside, and eventually gives up a pawn to win the exchange.
However, a well-placed knight on c6 and bishop on e5 pretty much leaves Stockfish devoid of chances.
ShashChess initiates a tactical melee with c5, but both sides have evaluated the position as dead even for a while, and the game ends with another perpetual check.

GAME 3

In an English line where black plays f5, Stockfish (as white) initiates play on the queenside and in the centre, rather than wait for possible kingside expansion from black.
Files open and the major pieces come off in a great hurry, leaving a dead drawn endgame.

As white, ShashChess makes the mistake of allowing a big kingside assault by Stockfish.
Although ShashChess survives the attack, the cost is high, with a lost endgame being the consequence.
First blood to Stockfish, which leads by +1 =3 -0.

GAME 5

In a Queens Indian with 4.a3, Stockfish (as white) breaks out from a passive position with 33.Nf4, which leads on to an exchange sac a few moves later.
Despite this, both sides estimate the position as dead even, and once the queens and a pair of rooks come off, the rook + 4 pawns v bishop + 6 pawns ending peters out to the inevitable result.

GAME 6

The reverse game took a completely different path, with ShashChess saccing a piece early to initiate a tactical melee that saw mass material come off the board.
By move 29, we'd reached a rook + 3 pawns v rook + 2 pawns endgame, which was insufficient for anything but a draw.
Still exciting for a short time though.

GAME 7

The Fraser Gamnit line in the Ponziani opening always sparks good debate.
Over the board, I always found it tricky for white to get any advantage, so it would be interesting to see how these beasts handled it. :P

After some interesting play involving the white king being stuck in the centre, Stockfish opted to go into a rook + 2 minor pieces v two rooks + extra pawns ending.
Although black's two connected passers on the kingside looked dangerous, in reality, both sides considered the position as drawn, and so it was just a case of seeing how the draw played out.

GAME 8

The game was repeated up to the stage where the rook + 2 minor pieces v two rooks + extra pawns ending was reached.
However, despite the game taking a different path from there, again both engines considered it as drawn.

GAME 9

The Schmidt Benoni line was probably a poor choice, as Stockfish (white) considered itself as having a good advantage (+0.89) when the book line ended.

ShashChess wasn't quite as pessimistic until its knight on h5 came under attack. Then the problems emerged, as the kingside opened up and Stockfish took over.
The piece sac with 24.Bxh7 was a nice move, with the extra pawns collected in compensation, giving white a winning endgame once the queens had come off.

And so, Stockfish gets a second win to lead the match by +2 -0 =7.

more_horiz
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.

GAME 15

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.

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

more_horiz
GAME 20

Stockfish opts to keep the position closed.
Eventually ShashChess opens up the h-file, but that only sees all of the rooks coming off the board.
The resulting queen + pawns ending leads to mass exchanges and a draw.

Stockfish leads by +2 -0 =18.

GAME 21

In a 1.c4 b6 line, Shashchess gets saddled with isolated doubled pawns on the d-file, but they don't appear to be a weakness, with an opposing isolated pawn protecting them.
After ShashChess initiates play on the kingside with 19...h4, the queens come off and black brings a rook into play along the h-file.
A few exchanges later, there is a rook +minor +pawns endgame, that both sides see as dead even.
Another draw results.
I found it an interesting game regardless.

GAME 22

The return game takes a different course, but Stockfish (as black) equalises easily enough.
Although Stockfish takes control of an open c-file, there is no advantage to be gained, and pieces come off the board quickly.
Another draw.

Stockfish leads by +2 -0 +20 with just two games remaining.

GAME 23

The final opening line in the match is a QGD Ragozin.
After all of the bishops come off the board, ShashChess initiates action on the kingside, but all that happens is that all other pieces end up being traded until a queen + pawns endgame is left.
Both sides see the game as drawn, although they play it out until the bitter end.

GAME 24

As has often happened, the reverse game takes a different course.
An endgame eventuates in which each side has two rooks + knight + pawns.
Although there is some interesting play as each side tries to create an advantage, the reality is that they both regard the ending as drawn.

Stockfish wins the match by +2 -0 +22.
