The 20M-hand policy the trainer was running on millenia, collected. 4,159 nodes,
which is barely more than the 300k-hand placeholder had — the info-set
abstraction is coarse, so what twenty million hands bought is better-converged
strategies at the same decision points, not a bigger tree. The heads-up hit rate
is 94% and chips still conserve across a hundred sessions of real hands.
