Tip of the hat to ChrisB for his positional sacrifice of a full dog on 9s. He didn't equalize material until 17s and didn't go ahead until 22s. Of course no bot can see eight moves ahead, so I don't know how they could cope with such good positional judgment.

Last year there were four(!) undefeated players, but only two with many games: Nombril and I. This year we play each other, so one of us must lose, but Nombril and chessandgo don't play, so they could still both be undefeated. To prevent that calamity, I just need to beat them both.  |

This is OK, I was already defeated so if you 3 decide to lose to me  ..., but novacat and rabbits are not so far from perfect record. Will Nombril stop rabbits or not?

What baffles me is that some of these postal games have barely made it into the double digits on moves. I could not play at such a slow pace as I would forget what I was analyzing and have to start all over again.

Sometimes it is an advantage to me to forget what I was thinking about and start all over. It is easy for me to get caught up in a single plan or single vision of the way the game will evolve, which is when I am most likely to miss my own best move or my opponent's best reply.
I do think, however, that this year has some unusually slow games, i.e. games in which both players have nearly drained their reserves. That plus topping 90 moves could hit the 300-day game limit for the first time in tournament history.

Yeah, I have games at 12, 13, and 15 moves...I'm very surprised by how slow I am playing. But do you really think we will get to 90 moves
Rabbits and I might make our next moves later this month, so you can see what just happened in our game...

I think he means 90 total moves (so 45 moves for each player).
I personally don't think that any game would ever get to the 300-day time limit as I think players would speed up eventually and either 1 would time out or there would be a result.

Yes, to hit the 300-day total game time limit would need each player to drain the initial reserve of 60 days and get 90 days of additional time by playing 90 moves. Each player contributing 150 days adds up to 300. This has never happened, but it could result in a very warped finish if it does, because one player will know he can win simply by drawing it out to day 300.

Briareus is presently 4-1 for a performance rating of 2238. (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.
Bot . Year Record Postal Performance
--- ---- ------ ------------------
Bomb 2005 4-6 1716
Zombie 2007 1-14 1409
Sharp 2008 1-8 1568
OpFor 2008 8-9 2060
OpFor 2009 3-7 1798
OpFor 2010 6-8 1848
Clueless 2010 9-7 2072
Briareus 2011 4-1* 2238* |
|
So it did it ... it is currently 10-5 and at least 2 of the remaining games are still open.

Which one is decided? I can't tell who will win any of the three.

If I understand English well, there is a difference between at least and at most. ... (I am very carefull not to be caught  ) ... but the game with Heyckie seems to be already decided ...

There is at least 1% chance that you are correct.

Oh yes the game is finished now and the bot is now at 11.

And looking at the games now I again see, how strong is the bot at the ending (exchange of HD for r against novacat forced by well defended hostages).

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.
