Re: polyglot book merging

I would like an additional option to not include fixed white lines from w1.bin in the merged w.bin book, when they are not part of the selected white lines in w2.bin That would be interesting for creating opening repertoires for over the board games. Than I would make a bin book w1.bin from my own ...

they are good for as long as they last, you've been warned.
I've had one for two years, two for one year. So far no problems, although I have no use for turbo boost and the like. I hope they last, they're the most power efficient CPUs I've bought, cheapest too.

Re: Downloading old development builds of Stockfish?

I can confirm that older executables aren't on the server anymore. For example, this is the original address for SF 2.3.1:

Re: Is e4 significantly better than d4?

Daniel pointed to the statistic of outcomes being more useful than an eval from the root The root may not be the best place to show that usefulness. I posted in this page a position, where even SF gives +4, but the result is a draw. Lc0 may even give a higher evaluation. In light of this shortcomin...

Re: Is e4 significantly better than d4?

No (I can do it with today's engines. We could build some tablebases from this position that output a drawing line against any opponent). But... Ok, so you can do it with current engine support. There may still be some positions out there, not covered by opening theory, that are complex enough and ...

Re: Is e4 significantly better than d4?

It'd be ridiculous only against perfect play, because then 1.e4 and 1.d4 draw and they're objectively equal, but we don't have perfect play around. Some people disagree with me on this, and say draw death hit us years ago, but those people also claim they can draw a game against all possible moves,...

Re: Draws are getting cheaper, are 15W enough?

You could say that the players may ask the TD to call the game a draw by one of the specific rules if it is clear that this outcome is inevitable. There will be lots of games where it is obvious that a fifty move rule draw is inevitable, and having to play out fifty pointless moves is a bit much to...

Re: Draws are getting cheaper, are 15W enough?

I would prefer that the total score given for the game always be 1 point, for several reasons. So I would say that for repetitions without check the side repeating the position for the third time gets less than half point, the other gets more, same as for fifty move rule. That's more neat, although...

Re: Draws are getting cheaper, are 15W enough?

Stalemate is too rare for that rule to do much, although of course it will change some basic endgames. Much more significant is addressing bare king (making king and minor vs king a win), and doing something about repetitions, at the very least those due to perpetual check should be either banned o...
