I'm not creating a new topic because it's the same rule, however the context is slightly different.
My opponent controls Tangle Wire with some number of counters. I control Dark Confidant. I go to my turn, stare blankly at my opponent with a lack of emotion and point at my Confidant and say "Resolve Confidant trigger?". My opponent says, "Yes.". I reveal the card.
Can they make me back up and resolve their Tangle Wire? This has happened a few times in various forms before and since the trigger policy changes.
Or in the above post, example #2, if I point at Tangle Wire and say "resolve Tangle Wire trigger?" and get a yes.
Doing exactly what you said sounds fine and I think most judges would call it a missed wire trigger. However if If you point to bob and say "trigger bob" rather than "resolve bob" (or don't say anything at all) and then proceed to flip a card when your opponent says "yes" I think things are a bit murky and a judge may make you back up if your opponent addresses the wire on the card flip and simply says he thought you were just putting the trigger on the stack.
Or if you are one of those people (with no bob in play) who just says "upkeep" waits half a second and then tries to draw a card to get a missed wire trigger, that is not ok either. By explicitly stating "resolve bob" or "move to draw step" and getting the opponent to agree to a specific game state after the wire should have resolved I think you are in the clear. But doing it just on timing alone is not ok since no priority passes have been explicitly communicated and there is ambiguity in the game state.
