Hello, welcome here!

Interesting. Is the standard starting position without a2 pawn the sole opening position? How you make sure that there is diversity in the openings then? Some diversity can be get by playing on several cores.

Anyway, I am expecting a very close result, say 11/20 for Komodo.

I use contempt value of 5 for K9.2 (15 default)

Houdini use 0 (1 default)

Larry urged me to use the lowest contempt available for H4, considering the relative age of the engine.

Although you left out number of threads, which is important information, I would predict a modest Komodo victory in any case. More threads means higher quality play which favors the odds receiver, but Komodo scales better with more cores than Houdini, so these things roughly cancel out. As long as you are using at least two threads, you should get reasonable variety by move five I'd say. The a2 handicap is pretty small, since White has both the first move and the half-open file as compensation. If Komodo does win, you might try the c2 pawn next, as that is more of a "real" pawn handicap. That might be tough for Komodo, but perhaps not too tough.

One question, - how do i post fen positions and games?

[Ajedrecista]

Hello Jon Fredik:

Thanks for your tests and welcome to Talkchess.

One question, - how do I post fen positions and games?

It is easy. For FEN strings, please type the following:

Code: Select all

[d]8/8/8/8/8/8/8/k6K w - - 0 1

That is: [d] followed by the FEN string.

Example:

[d]8/8/8/8/8/8/8/k6K w - - 0 1

Games are similar to post: just replace d between square brackets [] by pgn. Please note that you can post more than one game with the pgn tag. Example:

Code: Select all

[pgn]Game 1

Game 2

Game 3[/pgn]

Example:

Code: Select all

[pgn][Event "Game 1"]
[White "W1"]
[Black "B1"]
[Result "0-1"]
1. f4 e5 2. g4 Qh4# 0-1

[Event "Game 2"]
[White "W2"]
[Black "B2"]
[Result "0-1"]
1. d4 Nf6 2. Nd2 e5 3. dxe5 Ng4 4. h3 Ne3 5. fxe3 Qh4+ 6. g3 Qxg3# 0-1[/pgn]

[pgn][Event "Game 1"]
[White "W1"]
[Black "B1"]
[Result "0-1"]
1. f4 e5 2. g4 Qh4# 0-1

[Event "Game 2"]
[White "W2"]
[Black "B2"]
[Result "0-1"]
1. d4 Nf6 2. Nd2 e5 3. dxe5 Ng4 4. h3 Ne3 5. fxe3 Qh4+ 6. g3 Qxg3# 0-1[/pgn]

You can choose the game you want to see from the list on the top of the chessboard.

Regards from Spain.

I think that our results vs. Houdini will in general be worse on 2 threads than on either one or four or more. I'll bet Komodo would win this same match on six or more threads, maybe on 4. Maybe someone who has at least a six core machine will try it.

[Nordlandia]

I will like to try move + castling odds i.e H4 play white in all games and K9.2 is not allowed to castle. Is this a good handicap to test?
