Hi, With such a large number of playouts, the tree size limit (and so heavy pruning) is certainly a possible hypothesis. The simplest way to test it would be to run the same MoGo_17 or _18 with a much bigger tree (taking more memory). --collectorLimitTreeSize is by default 400000 (number of nodes). If you want to increase beyond 1000000, you should also add --limitTreeSize 2000000 (this limitTreeSize does not make much sense with the pruning, but it is a hard limit which, whatever happens, will not be reached... modulo bugs ;))
