1. Players may not look at any hidden posts not addressed explicitly to them.
2. Closed book - neither player may reference databases/AI/etc. to inform their move.
3. We may not ever look at the game on a board. We may only visualize the board from moves written in text form, ex: D4, 10-10. Our comments will be textual as well, of course.
(Note to spectators: Please do not include any diagrams/SGFs in comments addressed to us, it would ruin the fun.)
4. If we ever must go back and reread the text for the moves that happened - and we probably will if there is a long gap between play - we will mention it in my hidden comment for the move played.
5. If one of us reaches the point that they feel they can no longer visualize the game, they can declare an early end, pending on audience approval. I'll try not to do this, but I expect that by early endgame it's going to be too hard for me to keep track of everything.
In terms of how to give textual notation, I can most easily visualize with number-number (4-16) notation. Here's a map from the letters indexing diagrams to numbers for reference:
A = 1
B = 2
C = 3
D = 4
E = 5
F = 6
G = 7
H = 8
J = 9
K = 10
L = 11
M = 12
N = 13
O = 14
P = 15
Q = 16
R = 17
S = 18
T = 19
Unless you have specific preference, let's play an even game, 7.5 komi, Japanese rules.
Any further clarifications? If not, pick even/odd before looking in my hidden.
Good luck!
