I wondered that too, because the search tree frequently reaches positions by transpositions.
Only testing would say for sure. And even then, YMMV.

I mean, except for ko captures, it doesn't really add information to the position. The correct prediction rate is such an obvious metric, but maybe prediction shouldn't be improved at any price. To a certain degree, last move info is a kind of self-delusion. A predictor that does well without it should be a lot more robust, even if the percentages are poorer. Stefan
