CraggyCornmeal-browni3141 game rescheduled to Wednesday at 1 PM ET/10 AM PT (virtual slot "162") due to circumstances described in the chatroom.  The expectation is for all players to have at least 1-2 days' notice for the next round once it's scheduled, and additional rectification measures may be taken at that point.

Hi.  The WC event may perhaps be created soon.  Omar seems to be happy to go with something a lot like last year, which was triple elimination, although it might be good to discuss the time control, where the 6-minute maximum move time was turned on, but still with the high reserve to start.
 
Also it might be good to figure out exactly which pairing algorithm to use, as I believe I was not aware of subtle differences last year for the triple elims.

As a very belated historical note, the chosen values for the constants of HarLog, Q and G, are effectively fully determined by:
  • (as mentioned) being indifferent to an initial trade of a dog for 2 rabbits and
  • having the advantage of an initial trade of a horse and cat for a camel be exactly flipped after all the dogs come off the board.
This works out to finding the positive value Q that satisfies:
G = (Q^2 + 13*Q + 38)/((Q^3 + 15*Q^2 + 74*Q + 120)*ln(10/7)) = -2*(Q^3 + 5*Q^2 - 2*Q - 22)/((Q^4 + 11*Q^3 + 41*Q^2 + 61*Q + 30)*ln(65/56))

It had to do with a network setting, indeed. Thanks for the hint; I can play again!

Are the PDFs still available?  I've already ordered the paperback but would also like to have digital copies.  Thanks.

You can go to the "Navigation" Bar on the left of the gameroom, then select Games -> My Recent Games. On there, just click on the gameboard icon for the game you want to look at.
