Sure, but then all the analysis is either 0 ply evalutation, 2 ply
evaluation or one of two rollout contexts. In all, any data on a
particular move uses only one of 4 possible contexts. In a 21 point
match, we currently store perhaps 800 or so analysis contexts and
output those 800 contexts to the .sgf file. I'm proposing you store
and output only 4 contexts, then 800 moves with a simple index to the
analysis context which is applicable.
