Gambit engines?

[David Dahlem]

Ok, i've finally decided on the entrants for my gambit engine tourney. I settled on a No Book, Round Robin with 2 rounds, 132 games, time control 40/5. Hopefully there will be some interesting games.

I have a good idea who will win. Here is the lineup -

Code: Select all

    Engine               Score GaGaKoShTiTiJuTiTiDeDePr    S-B
01: Gambit Kitten        0.0/0 ·                          0.00
01: GambitFruit 4bx SE   0.0/0   ·                        0.00
01: Komodo 1.0 Gambit    0.0/0     ·                      0.00
01: Shredder 12 Kamikaze 0.0/0       ·                    0.00
01: Tiger Aggressive     0.0/0         ·                  0.00
01: Tiger Gambit         0.0/0           ·                0.00
01: Junior 2010 Gambit   0.0/0             ·              0.00
01: Tiger Anti-Human     0.0/0               ·            0.00
01: Tiger Suicidal       0.0/0                 ·          0.00
01: DeepSjeng Tal        0.0/0                   ·        0.00
01: DeepSjeng Redshift   0.0/0                     ·      0.00
01: ProDeo Tal           0.0/0                       ·    0.00

Will it work in Arena?

Dann.

I think your knowledge on this is far too much for this tournament.
You have done real tests and I trust more in your opinion.

It´s a pity there has been no reply to your sugestion.

Do you have a probable engine list in priority order?Also a list of Books?

Can you also tell the minimal Ply level at which Rybka understands most positions. That will simplify having to tell time controls for the ample range of hardware nowadays.

In my opinion there are engines which can play gambits with book, and there are fewer (probably a couple) which can play without book.

Best Regards.

Rybka is the only engine that understands gambits. You will need long time control for gambits. All engines butcher gambits at high speed blitz (unless they have very long book lines that cover them thoroughly).

Rybka gets the right moves in the Evans Gambit. No other engine I have tried is able to do that.

Thank you Martin. I'll check it out.

Cool!

PS: It has 2 more personalities built-in, called Gambit Agressive and Gambit Suicidal. Sounds like a LOT of fun.

Yes, does sound like fun. I have it now.

I notice there is a "Anti-Human option". Know anything about this?

It was an idea by Ed Schroeder, implemented in Rebel, to maximize complications and tactics. Theron and Ed were programming partners for a while and they swapped ideas.

Sorry Albert but while it is correct that Ed and I have been sharing ideas in 1999-2000, the antihuman option is not exactly what you describe.

First, antihuman was my own idea. I decided to implement it because some players used to make fun out of the engines (I guess it was in 2002 or so) by completely closing the position and winning of time.

So the antihuman mode in Tiger does this:
- it detects if the opponent is trying to use this strategy
- if so, it will open the position even at the cost of some material
- it will also slightly change its time allocation algorithm

Even today, Tiger is one of the very few programs able to defeat the "block and win on time" strategy.

I guess Pablo could show you some games where he uses the strategy against other programs, and wins, sometimes, and uses it against Tiger antihuman, and fails, always.

Please note that the antihuman mode will most probably do absolutely nothing against other programs. Including an additional Tiger with antihuman mode in a computer tournament is a waste of time.

Thanks Albert. What do you think would be the effect of using the "Anti-Human" option with the 'Normal' option vs the 'Gambit' option?

Antihuman will do absolutely nothing in a computer tournament. See my other post, it is designed to detect a very specific human behaviour (completely closing the position and try to win on time) and act accordingly.

It will never trigger against a computer opponent, and so it will play exactly like a Tiger without antihuman. You are going to waste your time if you add a "antihuman" Tiger personality in your tournament.

Thanks Christophe.

It's too late now, the tourney is almost halfway finished. Wish i had waited before starting it. Whatever, i have lots of time to waste.

Hi David, I see that is too late but u would try with Toga Chekov, Quark 2.35, Tao 5.6, Nejmet or Cyclone Extreme

hey david, fwiw i'm running my psycho junior against your komodo gambit personality in a 1+1 test using albert's gambit suite. at least, i hope it's against the gambit personality & not the default -- i'm not 100%, but i followed the instructions. i figure results could give an idea about tuning for rough equality for your gambit junior; i expect komodo to drub this version of junior but we'll see. interested in your gambit settings as they stand btw. you'll really enjoy your new junior engine, trust me.

Hi John. Yes, i do like my new Junior engine, so much that i made a logo for it.



Your Junior custom settings are doing surprisingly well so far in my tourney, very close to my Komodo settings. I'll post the standings at the halfway mark.
