Stockfish Variants, Why not Antichess ?

I see that some stray (performance-improving untested) code I intended to remove made it into search.cpp. Sorry about that!
github.com/ddugovic/Stockfish/commit/638336876aeefea16a7f61ad9826d3a258f19b0b

Sorry, I accidentally committed the wrong file. Here's the fixed commit URL:
github.com/ddugovic/Stockfish/commit/b70e32750e14d5041120b4e3c1e5883a869cf601

how can you guys remember all those codes ^^

#23 In the same way you can remember where en.lichess.org/forum/lichess-feedback/stockfish-variants-why-not-antichess-?page=3#23 is at... by using tools which can remember URLs for you.

Oh, i see thought you remembered it all in your head :D like

anyway im always impressed with programmers, i wish to study coding ^^ and sorry for going off topic

Thanks @ubdip . Yes I'd imagine so. Hope you find the time soon :)

still waiting for that antichess analysis :(

You can download (github.com/ddugovic/Stockfish) and compile it for offline analysis . In the middle- and endgame it plays quite well (compared to me), but it is weak in the opening. E.g. it cannot calculate deep enough to refute 1... b5 after 1. e3. That's why it thinks 1. e3 is a bad move. So the analysis results would not be useful in the opening and might confuse some users.

@ubdip

I see. But why is it weak in the opening ? and can you fix it? also do you think watkins lines can help in this case ?

by the way the link leads to wrong page :(

Since the Antichess engine is in a very early stage the evaluation function is not very elaborate yet. With only few pieces on the board the evaluation function is not that important, but in the opening it is important to balance factors like piece values, mobility, etc.

Additionally, there is the "problem" that Antichess is close to being (weakly) solved. Otherwise you would not know that the engine's opening moves are bad (e.g. 1.e3 b5?). This might sound ridiculous, but in my opinion it is an important factor.
