Match Play Double Match Point. How should Red play 31?

This is one of those problems that only a computer could find! I happily played 13/9* only for XG to flag that as an error.

With a live cube it would be the right play but at DMP all you want to do is win the game.

The best move to achieve that is 13/10, 6/5!! The idea is to damage White’s timing and give Red another three to play in home board (sometimes crucial against the 1-3 back game).

Even having seen the rollout analysis I am not sure I would have the courage to make that play over the board!
