The Doomsday of Stockfish DD

[Lyudmil Tsvetkov]

I hope Marco and his collaborators are taking notes.

Marco and co are swearing at me right at this moment.

I can go even as far as saying that it is worth incorporating such evaluation changes regardless, even if the overall rating does not go up, as long as the engine's play becomes more well-rounded, with visibly better play in such closed positions with flank attacks facing the king. I suspect most programmers don't agree with me on this, but SF is not even commercial, so if anyone were to try what I'm proposing, it could be them (the SF team).

At the very least, a special positionally enhanced version of Stockfish could exist, as a companion to the 'normal' (strongest) version.

Nice games and attacking ideas, Lyudmil!

CL

I appreciate very much what you say, Carl, but personally I think a stronger engine is always the better choice. Actually, strength and positional understanding go hand in hand. A stronger engine always plays better positional chess.

Strange heading for a subject (speaking of doomsday) of an engine you beat in a game which is dedicated to Don Dailed who passed away too soon.

[Lyudmil Tsvetkov]

Hi Carl, thanks for the games.

That is the problem with many test suites and opening books: they contain an awful percentage of unequal positions, just like the one you used. 9. Bd3 is very bad seemingly, somewhere to the level of Nunn . For me, after black's f3 in both games, white is hopeless. Probably the only white chance to hold the game would have been playing f3 itself. Interesting that Komodo does not find it at such a long TC.

You conveyed a point; nice comments btw.

I see what you mean regarding the opening, but while this position is not the best line White could have played (9.Bd3 is probably ?!), I can say that
a) White is not (much) worse objectively and should be able to draw with correct play for both sides
b)we are able to arrive at such an assessment only after much testing and analysis; John Nunn certainly must've liked his chances when he embarked upon this line with White

As a tester, I like this variation a lot since it reveals so much about the 'character' of each engine, and both strengths and weaknesses immediately can bubble to the surface after a smallish number of games.

For the sake of comparison I shall include the corresponding games SF played with White, showing how it was able to evade the pitfalls:

And it played f3 in both games, while Komodo was very slow in trying to play f3 with black itself.

Nice game, Miroslav.
Why do not you post your games with the [pgn] - [/pgn] tags to be replayable here?
I also later noticed that Stockfish mishandles some lines of the French. Unfortunately, the latest Stockfish plays the French much less frequently than the Ruy Lopez...

Hello Lyudmil,

I would like to do so, but I don´t know how... I am not IT guy

[Lyudmil Tsvetkov]

Second win against Stockfish DD (this time it was not played under equal time conditions...position was too difficult, so I was thinking about one hour).

Well, you just put the pgn between the [pgn] and [/pgn] brackets, right into the place where the and is.

Interesting, wild game, what was the hardware, did not Stockfish miss something later on? Waiting for a 3rd win. I gues you have been playing some 100 games per day.

Thanks for advice It was 1 core of the i7 4770K. Decisive mistake for me was h6. At longer times and/or when something is hashed it wants to play f6. This line is very wild. I have seen that playing Kasparov few years ago, so if I have opportunity I use it regularly :)White has ful, compensation for material. Normally, I play during my travel to work by train. And very often also in the evening. I play a lot of games, because I seldom play to the bitter end. When I see that Stockfish is winning, I resign and start new game
