In training games I think the rules it’s using do allow the removal of dead stones. If it chooses not to remove them it isn’t because it’s not caring about points it would have gained by removing them, it’s because it doesn’t think it would gain any points by removing them.
There is no possible habit of “always capturing all the stones to get maximum score under area rules”. Even under area rules you don’t get more points for capturing the stones (unless the stones are not actually dead according to the rules you’re using, or in human games according to negotiation with the opponent).
I think that currently under area scoring rules KataGo behaves in a way that it doesn’t capture all stones that would be dead by human convention but that are not dead by KataGo’s rules provided capturing them isn’t necessary to win the game.
That’s correct, at least roughly—the important difference is that it’s not “isn’t necessary to win the game” but “doesn’t make any difference to the outcome, including score difference”—but I don’t see what it has to do with the more specific thing you said above:
The problem seems to be that it’s not preferring to win by more under area rules.
KataGo does prefer to win by more, whatever rules it’s playing under; a stronger preference for winning by more would not (so far as I can see) make any difference to its play in positions like the ones reached by the adversarial agent; KataGo does not generally think “that it has enough points anyway and doesn’t need to capture stones to win” and even if it did that wouldn’t make the difference between playing on and passing in this situation.
Unless, again, I’m missing something, but we seem to be having some sort of communication difficulty because nothing you write seems to me responsive to what I’m saying (and quite possibly it feels the same way to you, with roles reversed).
What makes you believe that KataGo is “not preferring to win by more under area rules”?
