Could you provide an example? I’m trying to understand the scenario you are talking about. There are many scenarios where your opponent might play after you pass:
- The game is not over, boundaries are not complete (you are in the wrong, but it happens sometimes)
- Dame has not been filled (no one is in the wrong, filling dame is traditional, but often skipped in online games)
- Your opponent is contesting the life of a group (no one is in the wrong)
- Your opponent is a sore loser, and is making the game go on indefinitely (they are in the wrong, call a moderator)
I sense you are talking about (3). In that case, play it out. If you think you can pass without dying, do that, but take it as a learning experience if you are wrong. If you are irritated, you can take solace in the fact that this behavior becomes less common as you get to a higher rank.
