Not quite. The bot is playing well (and I have probably made some poor moves), but the exchange starts with HD for h. I will not spoil what happens after that. |

Oh I have missed the Rc2->Rc4 maneuver, what slightly changed your options. I can imagine the scenario for the rest of the game, but let us wait till the answer ... the game result.

Now you can see 38s which was quite sneaky.

OK, I must admit I like it, and I expected another move.
But the game seems to be in phase where there is a lot of almost equally good moves. I hope you will let logs after the mixer ends somewhere for download.

Yes, I can do that... It's a file per move, but it should be possible to sort them per game.

It happened today in the just-finished game against novacat, finding a goal in 4 at 46s (which novacat defended for as long as possible).

That's an impressive detail to add to briareus's impressive total score.

So and now after Fritzlein lost to mistre and novacat to bot_briareus we have last 3 candidates for all win score.
chessandgo is playing RonWeasley, Nombril plays none of them.
So there could be at most 2 such players.
Fritzlein plays them all ... let us see ...

Caution: Since these ratings are based on few games played far apart in time, they could swing wildly based on the results of a single event. In fact, I'll bet someone in this list has moved over 200 points by tournament end. I'll paste some current WHRP ratings here so we can compare later for an idea of the volatility:
Fritzlein 2772.9
chessandgo 2537.8
Nombril 2511.8
Adanac 2367.1
Hippo 2253.7
RonWeasley 2249.5
ChrisB 2174.4
ocmiente 2158.6
Tuks 2097.8
blue22 2040.7
mistre 2035.9
camelback 2007.1
omar 1990.5
novacat 1839.3
toby1kenobi 1749.8

Seems around 150 point difference is there often, but 200 points would not be achieved.

Aren't you jumping the gun a bit? Adanac is down 178 points and could still lose to me. I am down 154 points and could still lose to Nombril or chessandgo. And Nombril is up 105 and could still win his remaining four games!

So now it's Nombril and chessandgo.
Me and Fritzlein play them both.
(But I have no chance to beat them both  )

So final bot's score is known now. Congrats for the performance. If the logs could be visible somewhere, I would probably make a (quick?) look at it.
Thanks Ricardo for the games played in the mixer. So now we could fully use it's one day thinking time for The Gang game

(or 2155 if you calculate it the conservative way; in any case impressive) But briareus seems to be in trouble in the majority of its remaining games. To top clueless's record performance of 2072 last year, briareus needs to go 10-8 overall, i.e. winning six of its remaining thirteen games. That's a tall order, but there are enough tense games that it is definitely doable.

So briareus' tournament is over. Shout out to woh for launching (and winning) a goal race in the last game after briareus had already displayed some fabulous goal racing ability in earlier games.
Briareus set a new performance record of 2167. Skeptics could point to the game against Donald which was not won over the board, and was against a mysterious player who was probably overrated at 2322, but even neglecting this game would give briareus a record at 2126.
In postal chess, humans held out against computers for far longer than at real-time chess, but the same pattern seems not to be holding for Arimaa. In the 2011 Arimaa Challenge screening match, marwin and sharp earned performance ratings of 2110 and 2109 respectively, below briareus' result in the 2011 Postal Mixer. Humans seem to be losing ground to silicon with no island of safety.
Congratulations rbarriera! This is an impressive performance that I would have given odds against at the start of the tournament.

Thanks Hippo and Fritzlein. Even though 18 games is not a very big sample, I am indeed happy with Briareus's performance in the tournament.
I'm looking forward to see how it plays in the next postal mixer, now that people got some warning . It would be interesting to see Marwin play its first postal tournament, and to see Clueless and especially Sharp play again (since it hasn't entered since 2008 ).
I will post the logs later today.

Here are the logs:
http://109.74.204.218/arimaa/briareus_postal_2011_logs.zip
I grouped them by game, each game is in a separate folder with the opponent's nickname.
The scores are about 33.69 per rabbit (they were based on FAME's raw output and not scaled), 1000000 is a win score and -1000000 is a loss score. The variations are printed out in square from/square to notation, and push steps appear in inverted order (never bothered fixing that yet).
PS: There are some moves which have two logs, that happened when the computer lost connection to the Arimaa gameroom and had to restart for that move.

Congrats to the very nice score for Briareus!
And after checking a little in the log files, I just need to say that you have a very nice nodes count per second. Marwin is only pushing around 700knps, even if you have stronger hardware Briareus must be like 5-10 times faster. Maybe that's where I should focus my effort right now...
