thanks, I agree 1400 is about as far as simple UCT will get you.
My simple UCT implementation (myCtest-xxk-UCT) gets about
1200, but it does not do any adjustments to the number of playouts
per move depending on the time remaining, so I have to limit
it to 40k playouts per move.
Have you thought about using the partial tree of the previous move
as a bias?
