Re: The Bryntse Gambit

If we only play optimally, we only get to 1.c4
So I guess the assumption is that we get to the gambit position, by hook or by crook.
It's all the way out here:

Re: LC0 For Android!!! History Made!!

On the other hand, it might be fun to have something that sounds powerful and yet does not beat your brains in every single game.

And you can say, "I beat the world's strongest chess program the other day!"

Re: LC0 For Android!!! History Made!!

Do android devices have powerful GPUs?
If not, then I guess it stinks on android.

Re: The Bryntse Gambit

I currently have 2146 positions for this opening in my main EPD database.
Might grow, with some more investigation.

Re: The Bryntse Gambit

This may not, though. e.g. after 3.Ng5, SF prefers all of 3... Bf5, 3...e5, 3...Nc6 and 3...e6, with advantage for Black. If the line is followed to 5... Kd7, then White can get an advantage without sacrificing by playing 6.f3 exf3 7.gxf3 Bf5 8.Bb3. SF, depth=40, evaluates this as (+0.95). rnbqkbnr...

Re: Bad Bishop win

Of course the same thing is true of every chess heuristic. A knight on the rim is dim. Except when it is the best move. Knights before bishops. Except when it is better to move the bishop first. Never develop rooks or queens until after the minor pieces. Except when it is the best thing to do. Piece...

Re: Bad Bishop win

Some internet goo on good and bad bishops: Good vs Bad A good bishop is on the opposite color as its pawns. A bad bishop is on the same color as its pawns. For example if the white pawn structure is c3, d4, e3, f4, then the light squared bishop is the good bishop and the dark squared bishop is the b...

Re: Bad Bishop win

As to 'there is no "correct"': 1. One definition of correct would be that it gains Elo in the desired environment of play. 2.
