Re: Hash collision?

Bob Hyatt has already done the research on the required hash length many years ago. The result was that 32 bit are not sufficient, 64 bit are, and you can even get away with 48 bit. Obviously, you also have the implicit storage via the hash table index, minus the bits for your number of slots. You c...

Including underpromotion to knight?
Yes, it's not worth the effort in QS. In main search however, underpromotions should be searched.

What about Rg8 by black?
Then Rh1-h7. After Rd8xd6 and Rd1xd6, White threatens to take the bishop on e6 with check. The covering pawn on f7 is pinned because of the queen on b7.

Isn't it a bit offensive to say that I am weaker than Ke Jie?
I'll take that back the day you beat him in an over the board match without computer access. Shouldn't be a problem for you to cut through the Go world where the top professional players are so stupid, right?

Are you implying that I am weaker than Ke Jie?
Of course, that's why you need a computer to find the blunders.

The same happened in chess: "oohhhh Stockfish is swinging form +3 to 0, he threw away his win, it's soooo obvious." Yeah, sure.

Re: Why are super top professional Go players so stupid?

Why are super top professional Go players so stupid? Because it's much more difficult to find the right moves over the board. In chess, it's been for a long time that every patzer can start up Stockfish and, lo and behold, find much better moves than the champions played in the actual match. The on...

Re: android build

To compile with make I created a bat file: That looks quite familiar to me. :wink: However, with NDK r19, building the standalone chains via the Python script is not necessary anymore. For now, this still works, but that will be removed in r20, see the changelog https://github.com/android-ndk/ndk/w...

Re: TCEC new interface

More likely, it requires java script. When I block JS completely via uBlock Origin, I don't even get the drop down with the seasons - the whole area is grey and empty. Also, no board visible. That's no wonder because the TCEC website is built with Bootstrap - which requires JS. Btw., I like it when...

Re: TCEC new interface

I have a very aggressive firewall (for instance, I cannot see the chat stuff) so maybe it is removing something. Your browser or firewall or ad blocker seems to be blocking third party fonts. I'm browsing with Vivaldi (Chromium derivate) and have this filter rule in uBlock Origin: "*$font,third-par...
