I am wondering how it's possible for slow MCTS to see forced reduction faster than fast alpha/beta search.
If it's a true mate announcement, they both have to go through an entire tree.

Is Leela doing that when it announces mate?

Probably better to play out some games starting in this position instead until SF better handles shuffling pieces.

Re: Policy determining quiet early opening preferences of Leela

Besides, apart from critisizing others test, do you sometimes post your own over here? If you want to prove something about "real engine strenght" without TBs, just run your own test. It was you who posted responding to Kai's tests. Look at your first post on page 2. You sounded confused about the ...

Now you are sugge...

Re: Policy determining quiet early opening preferences of Leela

Neither engine should get TBs. It's supposed to be a test of their endgame play, not whether they can look up TBs. It depens on what you mean by endgame play. For me endgame play in much larger than converting TBs positions. It doesn't matter to me if the engine cannot mate with N and B against a b...

Do you mean both engines got 5-men TBs?

Neither engine should get TBs. It's supposed to be a test of their endgame play, not whether they can look up TBs.
