Hi
Dragon 4.6 the french monster destroyed me in the first game as I tired to build a solid defense but at the end I blundered heavily and lost the game .....
In the second game I steered the 1. b3 opening into a draw position hoping to outplay it in the end game abut yet again due to poor late middle game skills I only managed to escape with half a point ....
Regardless of whay I wrote above,Dragon 4.6 performance is relatively weak against other chess engines but seemingly tuned anti-human when programmed maybe ....
Standings so far:
- 1. CT800 1.40 x64 13/18
2. Amy 0.8.7b 11.5/18
3. Dr.Deeb 11.5/16
4. Tigran 2.4n x64 10.5/18
5. Gosu 0.16 9.5/18
6. Dragon 4.6 8/16
7. Patzer 3.61l Leiden 7.5/18
8. Patzer 3.80 7/18
9. KnightDreamer 3.3 6.5/18
10. Simplex 0.9.8 x64 1/18
Where do you get all these engines? I tried the links on the CCRL page for every one of them (except top and bottom), and in every case I get some error message or strange website, I didn't see a single one available.
Hi Larry,
In general I take a first look here :
http://www.computer-chess.org/doku.php? ... nload_list
Most of the engines I find via Google and then if this fails,I ask here in the forum
OK, thanks, at least Tigran and Dragon were available from that list. I don't have time for multi-hour games but I thought I might try some 10' +5" games with them just to get an idea of the level. In general fast time limits favor the engines so I probably won't do well, but at least I should get some idea.
Cheers,
Dr.D
It will be interesting to play against them even at this short time control ....
Well it's getting harder to get a win climbing the rating list I didn't even scratch the 2450 level ....
A lot of draws and no wins for a long time now ....
The only engine I got working easily was Tigran 2.4n, but that was a good choice anyway as I believe it got a win and a draw from you and is in third place among the engines on your list. I played two games at 10' +5" (on my fast laptop, same speed as your fast computer), one with each color, opening book on, and got same result as you. I drew easily with White, even had better chances at various points, and lost an exciting game where I sacrificed for attack but it defended well. Probably I'll need to play more games to have a better idea, but allowing for the fast tc I would say that it should probably be rated somewhere between its 2183 CEGT rating and its 2400+ CCRL rating, which is probably what you would say as well. It makes too many strategic errors to be considered really strong, but it does reach high depths which makes it tactically accurate. Maybe the newer engines can outsearch old ones due to LMR and such, but if they have similar ratings it must be due to far less chess knowledge than the best ones of twenty years ago, and I think this matters much more vs. humans than vs. other engines. I suppose this is your point too.
Here are the games. I don't know why all evals show 0.01, but it doesn't matter, it is playing properly as I've verified with some games vs. other engines.
