The PolaChess tournament is the ongoing PolaFlow chess tournament. It is a Round-robin, 10 minutes time, 0 increment tournament played during coffee time. Both a PolÆlO rating and centipawns are computed. The person in charge is Carlos.
An Elo is computed, with a $K=32$ constant and with 5 provisional ratings for players not part of the PolaChess pool (we assumed established ratings for everybody who joined the tournament at $t=0$, which is not a problem as their ratings will converge but we need to take into account occasional games as provided by visitors). Specifically, the $K$ factor is scaled by $3/\big(4(5-i)\big)$ (i.e., down) for the established player and by $3-(i-1)/2$ (i.e., up) for his opponent for the first $i<5$ games of the new player, after which point $K=32$ again. Explicitly, the $K$ constants for the new player go:
while it goes, for the established player:
23 February (2015) — Blunderful.
The end was not recorded as it was too fast for the transcript (Pablo). Apparently an illegal move was made with a rook. The game ended in checkmate in a race to flag for time.
Camilo wins on time. Interesting, 26. Qd6+?! is not a blunder (only a mistake). The next move, however, is a proper queen panick moment.
Based on Computer's random sampling. Games that cannot take place are either skipped of flushed to the end.
Decided at the last minute on people's availability.
