This is a curious rule, does any actual existing bot use a rule like
this? It seems immensely ineffective.

There already are UCT reference bots, aren't there?
I personally think it's best to follow the seminal papers or existing
implementations with code available.

I've found that AMAF gives very little boost with light playouts,
you really need something fairly meaningful already to get any kind
of real boost. To have at least 10% chance of beating GNUGo with
reasonable time per game (to be able to play-test your bot), I think
you can't avoid doing a lot more than plain UCT + AMAF + light playouts.
