Ultimate Tic Tac Toe [Puzzle discussion]

I used MCTS. I have 2 questions. How to reuse tree, and how beat the Silver Boss ?

Hello,
What do you think is the best opening when you play first ? i tried the center and the right corner of the central square but i don’t see much a difference.
What move did you use in your own game ?

Hello i d’on’t know how to reuse trees, maybe by storing theme inside a code variable.
for the silver boss did you setup a bitboard ? it might help.
Just let me know about it
cheers

Hi, I use a Bitboard like vector grid size 12, 9 grid, 1 general grid and 1 for draw in general grid, one for each player.

The best opening is center, almost all in legend use it. In addition, there is so called “teccles” opening heuristic that for few first moves, when possible, you choose move that goes back to your current miniboard (i.e. if you’re in left-upper corner, you choose left-upper corner move). It increases winrate, but it’s not always best play. I think it’s safe to do this within first 12 or 14 game turns.
