Re: can engines see mate in 999999 in a big board?

It will depend on the engine, of course. If it has a recognizer for KQK it would. If it had material-only eval, it would not, and couldn't even secure a win. With a simple eval that awards centralizing the Kings, and minimizing King distance for the strong side, it would be able to win this at very ...

Re: Similarity Report 2019

Why didn't he think about curating the Similarity Report 2019 thread of posts talking about EO? If the main post on it wasn't about EO, then only the offending posts would need to be moved, and not the entire thread. You should have looked at the timestamp on the postings in the thread I moved to E...

Re: Similarity Report 2019

As far as I am concerned it is not yet going beyond discussing the reliability of various methods for determining origins. Which, as I already wrote in the lead posting, should be perfectly OK here. Specifics of the Crafty-Fruit comparison are all in EO; it is OK to refer to that here. I do not expe...

Re: Similarity Report 2019

The amount of noise doesn't really matter, because it is all in the same thread. Which I created anyway to refer to the moved thread. By diverting the noise here, the original thread stays free of it. Not sure what 'last time' you are referring to. I haven't moved any other threads recently (or perh...

Re: Similarity Report 2019

I guess I'm just being nitpicky about the description of the subforum there, if you remove "source code", it reads "Discussion of the origination and/or derivation of computer chess programs", then a similarity report would fit there. I admit that the addition "source code" in the description is st...

Re: Similarity Report 2019

EO threads should be only about source code discussions (as the description of the subforum says.) A ridiculous suggestion. There cannot be much discussion about engines for which the source code is available. The whole purpose of such discussions is to expose code thiefs who release executables on...

Re: Fast Queen Promotion on Electronic Chessboard

In WinBoard there is the option "Nearly always promote to Queen", which switches on "detour underpromotion". In this mode moving a Pawn directly to the promotion square automatically gives you a Queen. But in the rare case you want to under-promote you can still do it by first pulling the Pawn backw...

Re: On-line engine blitz tourney July

The ICS maintains 'lists', and has a command that adds an item to a list. I always use the predefined alias '+' for this command. So "+computer Nightmare" would add Nightmare to the 'computer' list. And this list is used to add the (C) to printed player names. I don't remember whether the computer l...

Re: Similarity Report 2019

Not if a thread in the General Topics section with the same title refers you to it.

Unless you are too stubborn to look in the EO section as a matter of principle, and then it is your own fault.

Re: Similarity Report 2019

Note that I created this thread in the General Topics section at the same time as I moved the original one exactly to prevent the problem mentioned by Ovyron; members not normally reading Engine Origins would be made aware of the Similarity Report thread, and could go there when they are interested ...
