Hi Eelco!

Your Engine "Toga Checkov Beta 3f 'prerelease" (Prerelease) on the site by Tony T., does not work on my Intel Core 2 Duo. Can You it new compile? I do not know what ist here wrong. UCI does not work.

Best!

Thank You.

I think this Toga does sometime play a bit risky

Odd, I find the original more risky (In the sense that it takes greater risks, not more risks). And, about playing style, Toga Checkov Beta 3 is awesome! You have to watch the games it plays to have an idea, as it seems to enter into dangerous positions and come up alive!

Wonderful playing style (Though, the original was still pretty good, the Checkov version seems to play even better.) Thanks for sharing!

Thanks Eelco.
Looks good so far. Just now starting 50 game tournament.
Toga checkov vs. Rybka 1.0. So far Fruit 2.3.1 is the
only one in the free eng. that i have tested that has beat
Rybka 1.0. in 2/12 Bltlz.

Best to you,

Gerold.

Why do you guys keep saying that the guys name is Tony T. His name Jonas Conas or something. Again, its a pirate site, stop visiting it.

Hello Eduard, thanks for the interest but what are you doing on that pirate site? You know the best clones can be found right here! And we have the best arguments about it too. Who is this Tony T. character anyway, sounds like a false name to me... Did he not play in one of the Godfather movies? Or was that Tony Danza?

But more seriously, thanks to Denis Mendoza there are now I think much faster compiles and I hope the Core 2 Duo version he compiled with the actual Intel compiler will be to your liking. Thanks Denis! Great Job!

Thanks Ulysses for your praise, but the credit should go to Fabien Letouzy I think for making 95% of this engine back somewhere in 2004 I believe? And it is still competitive today with the added search improvements mainly from Thomas, say another 4% of the program code.

I did not actually see much of the play yet of this particular version, all I did was watch what it did as the PVs, and hopefully solutions, of the Arasan test flashed by on the screen, to test for some tactical accuracy.

This version played some games against the Belka 1.8.11 version and here there were only decided games so I wondered if it could actually play draws... So my impression of the style is a bit limited as far as the minor changes in the source are concerned, but the Checkov settings are of course a lot older and have seen more tests against various opponents, Rybka 1.0, Deep Sjeng and others. Trying two checks in QSearch was kind of new though, such added check searches can be expensive but as I was going a bit for tactics after Charles had optimized for the endgame and positional testresults in the 3.1.2 SE, I thought it worth a try.

This version missed one or two of the positions in Arasan 7 that it should have found maybe, but then it was very fast in some others or made a different move that also seemed strong enough and a surprising move can also be beneficial in a game.

Just checking the PVs can sometimes tell a lot without actually looking at the board or having the position in your mind, it is a strange thing how that works, some pattern recognition I think especially with numbers and the sequence of moves flashing by but I don't think they get actually translated to chess positions. Not completely anyway or consciously, but the actual position is maybe somewhere in the back of your mind and in the corner of your eye too of course when the moves are made on the screen. The difference in evaluations between programs and the different moves in the PVs are also an indication of how the game is going and which program is doing better, even if the height of the eval does not say all, and almost independant of what the actual game position is at the moment. A different sort of pattern than the actual chess patterns that a good chess player can recognize much better than me, maybe more a differentiation to another mathematical pattern than chess is.

Anyway I am getting a bit too philosophical maybe, thanks for the observations Ulysses!

How can you close the source to Fruit if the original source was under GPL?

Hi Eelco.
Timecontrol: 5 minutes
A friend sent to me Toga II 3.1.2SE MP. Is this version legal?
