It can be 90 as an example (This value is used by Prodeo's >GrandMaster's personalities and it seems very good). Why Tweak it? Play against it at full strength!

Let's suppose the king is worth 100.00 The King is of infinite worth! so when you >checkmated it, your score is 100.0 Your score is # Mate! since all the other pieces you captured don't >matter, you've won.

Your analogy Sucks! so a score of -19.00 (A queen and two rooks) is not a game won, and thus >it's a draw since noside has an advantage. > >(I'm just multiplying your statement by 100 and it seems to not make sense, you >have to say when is the game won and when a side has an advantage, on pawn ahead >is as good as 0.99 score ahead). 0.99 Is NOT a pawn ahead! 1.0 IS an eval of a Pawn ahead! > >I'm doing just what you're doing No, you're Not, I'm stating FACTS; you, are wildly speculating, & Spouting nonsense! >so you can see how you look posting stuff like >that on a forum. > >Take care, and don't write to strangers on a forum ;o I don't take kindly to fools and Knaves, so will ignore you in future!
