Your suggestion strikes at the heart of the matter.   If you could do
accurate opponent modeling you would get more realistic scores.   Realistic
in the sense that they would more accurately represent your chances of
winning.

I was thinking of a similar solution to yours but I wasn't thinking
directly in terms of opponent modeling but instead some modification to the
playouts that is more in line with how a player would maximize his chances.
    However I realize that we still have a lot to learn about playout
strategy as it is and so this may be a very tall order!     I doubt this
would be simple.

You asked if a playout could be tuned to represent a 1d player,  but I
don't think playouts are nearly as strong as a 1d player.   The playout
strategy is a black art as they say and I think it's been established that
the goal is not necessarily to make the playouts stronger but to make them
better predictors.
