Interestingly, the (3-ply) bot does NOT see strewing four blots around the board as a positive thing, though neither does it like your play of making the 3 point, which was also mine:

(Interestingly, if we have our 8 point instead of our bar point, then it does like hitting.)

On the rollout, making our board does a bit worse still; but now the bot DOES like strewing the four blots (John's play):
