Re: On the ownership of TakChess

From - That would sound reasonable if Ed wasn't firmly in Quentin's camp... And - No, I was referring to an e-mail Ed sent me when we were discussing how to fix the forum. Ed said my plan to test on another server, directing all traffic there, could not be attempted without Quentin's permission, be...

Re: On the ownership of TakChess

Well, nothing was agreed by me, as there wasn't anything to agree on yet. It is not clear to me: does the database and the experimental newsite also contain the user data (email, password ...)? Because in that case it would be a pretty big violation, at least under EU law: user data must not be mad...

Re: Task force TalkChess access

Well, Ed's fake news is doing a lot of damage. In fact Quentin has no objection at all against the TalkChess poll function getting fixed. And it makes absolutely no sense that he should. BTW, looking at the code I noticed there is a variable $update, which is used in conjuction with $s_can_vote to d...

Re: On the ownership of TakChess

Well, nothing was agreed by me, as there wasn't anything to agree on yet. YOU wrote to Quentin: In principle we will try to solve the problem so everything we remain the same Assuming you meant "will" where you wrote "we", I took this to refer to a permanent move, not to running experiments on a moc...

Re: On the ownership of TakChess

Indeed, the replacement forum is already there, and it in a short time it can be made superior to this one, as we have full access to the software there. But I don't think that it will attract any visitors, no matter how many fancy features it has, and how crappy the forum is here, if it would be i...

Re: On the ownership of TakChess

That would sound reasonable if Ed wasn't firmly in Quentin's camp... You're alluding to Ed's attempt of bribing Quentin as owner to prevent democratic elections regarding the CTF shutdown. However, since that attempt failed, I don't expect Ed to be in Quentin's camp. Quentin wasn't a useful tool fo...

Re: The cost of check & discovered check in bitboards

So someone claimed that pruning all checks would be better? That seems plain nonsense.

Re: The cost of check & discovered check in bitboards

I think you are missing one scenario, what if the piece is moved in the direction of the check? For example, white rook attacking a pinned black rook or queen. the rook could retreat in the line of check with no discovered checkmate, or, could leave the line of check and put his king in check. That...

Re: The cost of check & discovered check in bitboards

I am not sure what you mean by 'ignoring check'. Testing moves for check would not buy you anything if you didn't use that info to search moves you wouldn't have searched otherwise. So what exactly are you talking about? Searching checks in Quiescence Search? Just detecting whether a check is a chec...
