Re: SF6 eval command output

You could modify SF's source as Eelco recommends, or you could calculate it mathematically (easy to do, but will be quite time consuming if you intend to look at more than a couple of positions). I am not interested yet on modifying the source. No problem with calculation the script will do it, and...

Re: King psqt

Hm. Have you looked at the material imbalance tables? I notice that knights gain a significant bonus with more pawns on the board, whilst bishops gain a significantly smaller bonus. As the game progresses, not always but generally you'll see the number of pawns on the board decrease, and so the knig...

Re: King psqt

You might be right about the rank 8 middlegame values being poorly tuned, but it seems like it should matter very little in terms of ELO, as it's extremely rare for the king to reach so advanced a rank in the midgame, and most realistic search lines should run out of depth due to reductions and prun...

Re: King psqt

I believe you're misinterpreting the PSQT. PSQT values are not penalties, but bonuses. So what you're seeing is that in the endgame, SF prefers to have its king centralized. I am misinterpreting nothing. Of course, they are bonuses, and not penalties. Here is my corrected table, but I did not corre...

Re: Chain, duo, connected

Well, a chain pawn is any pawn that is part of a chain, but here we will mainly refer to chain pawns as to defended pawns, as the base/undefended pawn of the chain is much less significant and actually only due a penalty. Duos are of course, according to Kmoch's definition, 2 own pawns next to each...
