Yeah, i think teires and determining whats actually going on pose the biggest problems with the current, or any, implementation of this thing.
The main focus of that anti-stall feature are the situations where game is done, player A passes but player B plays a random stone which has neutral or negative effect on their score, A passes again and B plays another random some, and so on. That unfortunately happens quite a lot, most often in beginner-level games where players might be unsure whether game is done or not, but also some within the higher ranks when someone just refuses to end the match :<
The problem is making a clear distinction between that kind of kind of stalling, and the situations where player A passes too early and player B plays a normal move to continue the game. Espesially if the “normal move” is some sort of mistake according to ai’s analysis, which usually is the case since most moves played by humans are sub-optimal
Teires are extra tricky, because those create situations where player A can pass multiple times without losing any points, but in order to count the score correctly, player B should keep playing moves which have neutral value until A is forced to add a move inside their territory. If theres multiple dames which need to be filled before the aji in teire starts working, then filling those dames is the right thing to do for B.
But that anti-stalling system is still really new feature, i expect it to be tweaked more than once in the near future ^^
