When you get your wish and win the World Championship, the pressure will be on you.  Then you will get to have people be disappointed in you for losing.  (Actually maybe a lot of people would enjoy being the point man more than I did.  It is an implicit compliment when everyone expects you to win every game.  I didn't enjoy the pressure, though, so there has been a side benefit of not being the best any more...)

I guess I'll have to try not to do that then Wink
The stronger I get the more human the top players feel because I still feel pretty human and whoever is left stronger than me must be only a little stronger, and therefore only slightly more inhuman Tongue. I have to stop pretending that you, chessandgo and hanzack are invincible against these bots at longer time controls. It had felt that way for a long time. This victory for briareus worries me a bit. The gap is getting too thin Sad. I hope that we can widen it again.

I agree that the narrowing gap is worrisome, which is why I was glad to see hanzack win the World Championship last year, and why I am rooting for you this year.  We need fresh ideas to push back the boundaries of human understanding of Arimaa.

I think I'll try and look over the game soon.
 
Only two of the official postal mixer games are left.

The win-loss difference and the internal performance rating are based solely on the 99 postal mixer games.  However, the rating change is based on all rated postal games that finished between the start of the event in April and November 13, 2012.  Thus, the rating change often appears inconsistent with the other results.
 
The internal performance rating was calculated using woh's  In Tournament WHR Calculator, with a "prior" of one win and one loss against a dummy player with a fixed rating of 1500.
 
Fritzlein and browni3141 tied for best win-loss difference, with bot_briareus a distant third.
 
Fritzlein had the best internal performance rating by a wide margin, with Adanac, browni3141, Alfons and chessandgo tightly bunched for 2nd through 5th.  bot_briareus came in 6th.
 
browni3141 had the biggest rating improvement, with bot_Hippo not too far behind.  bot_briareus came in a distant third.
 
The only undefeated players over the time of the event were Fritzlein (11-0 in the mixer and 0-0 in other rated postal games) and Alfons (3-0 in the mixer and 8-0 in other rated postal games).  Go Rockies!
 
Quite an impressive performance by the two bots!

Thanks for the summary, ChrisB.  I need to file away a last moment of glory before browni and Alfons start dominating future Postal Mixers.

bot_Hippo gained a lot of rating points in the autopostals, but now it will lost a lot of them ... it is losing in most of it's games now.
