Made position immutable so now I get this: var nextPos = position.Move(mv); var key = KeyFactory.BuildKey(position.Board); var nextPositionHistory = positionHistory.Add(key); var nextPsqValue = psqValue + position.CurPlayer * mv.PieceSquareDelta(position, PSQTableEval.PieceSquareTable); Actually pos...

Now I have this for alpha beta search. Don't like it. Too many if statements. ISearchResult SearchMoves(IChessPosition position, IMovePrioQ prioQ, IVariation initialVariation, int depth, int plyCount, int lb, int ub) { if (!(TimeManagement.SearchExpired(Level)) && (initialVariation == null || initi...

Maybe do a monthly perft competition for those who have their engine not ready to play games.

O wait if you do a good rewrite computing a perft already a problem.

Yes looks better. But I saw a video about monads recently. Although i am not sure I understand it. Don't know anything about category theory. So maybe I could use something like a monad to hide some obvious recurring tests. Monad is a functor plus a flatten operation I understood. Already unfamilia...

I skip this time. Source code in huge rewrite.
Don't want to participate with an old version because it would play the same as before.

Functional programming is probably best. So every time you make an assignment you should 'apologize'.
Pity that copying a board position is already too costly.

I even don't mind 2+1 or less. Just finish the tournament in one hour. If engines are really strong one can't understand 5 minute games real time. So results and games stored is only what counts. The shorter the tournament the less chances of disconnected engines. [My engine only plays stupid moves...
