Houdini 6.03 64-bit 8CPU v Stockfish 181117 64-bit 8CPU

[Graham Banks]

GAME 48

Houdini's 13. c6 led to an interesting period of early middlegame play, which resulted in Stockfish cleverly equalising. Most pieces came off soon after, leaving a rook, minor piece and pawns endgame. Another draw, leaving Stockfish leading by 25.5-22.5 (five wins to two).

Hi Graham,

What are your adjudication rules in this tournament ?

I see many draws end with 5 pieces (then obvious), but not all !
And how about the wins ?

Adjudication similar to TCEC ?

TIA

GAME 49

Stockfish thought that it had a nice advantage throughout most of the game, but that was illusory. In reality, all of the pawns remained on the board and once the minor pieces came off, the position was pretty much locked up. After much shuffling, the game predictably ended in a draw. Stockfish leads by 26.0-23.0 (five wins to two).

GAME 50

The return game developed differently, quickly opening up. With 21. Ng5, Houdini initiated a sequence of exchanges that led into an early rook and minor piece endgame. However, once each side had its passed pawn eliminated, the game was an obvious draw. Stockfish leads by 26.5-23.5 (five wins to two).

GAME 51

Houdini looked as though it might want to pawn storm the kingside, but Stockfish remained solid. With counter-pressure down the c-file, Stockfish held the balance. Houdini eventually carried through with its initial plan of thrusting its kingside pawns forward, but there was no real threat now and a drawn rook and pawns ending quickly came about. Stockfish leads by 28.0-25.0 (five wins to two).

GAME 52

Again, the reverse game developed differently, with castling on opposite sides. Stockfish was able to defuse any attacking threats on the queenside through its control of the d-file and its own seventh rank. It wandered its king over to the kingside and the game was eventually drawn. Stockfish still holds onto a three point lead and only requires one more win to take match victory.

GAME 53

The lure of a semi-open h-file with Houdini having castled kingside saw Stockfish castle queenside, with aspirations of an attack. Houdini seemed unperturbed, making sure that it had control of the centre and remaining solid on the queenside. Houdini's plan was always to meet the eventual gxh6 with g6 and using its king to block the h-pawn. Stockfish was left with nothing to follow this up than to break the centre with pawn pushes. However, this also involved the queens coming off. Houdini eliminated any further potential trouble by giving up the exchange to get rid of the remaining white pawns, thereby ensuring a draw. Stockfish leads by 28.0-25.0 (five wins to two).

GAME 54

Houdini gave up its g-pawn, so that it could castle queenside and start an attack against the Stockfish king. Stockfish responded by breaking open the centre and getting rid of some material via exchanges. Houdini then coaxed Stockfish into snaffling its h-pawn, leaving the g-file open, while also being able to advance its passed d-pawn. Then just as Houdini began feeling optimistic, Stockfish sacced the exchange to leave itself with queen, knight and two kingside pawns against Houdini's queen and rook (the queenside pawns looking rather inconsequential). A draw followed shortly afterwards. Stockfish leads by 28.5-25.5 (five wins to two).

Hi Graham,

Actually in this game 50, ending with 67. Bc7, why is there adjudication ?

No 50-move rule, no repetition, evals far from zero...
(actually I am trying to answer the question of a friend... )
