My understanding is that it's common in limit games where usually there is a 4-bet (or 3-raise) betting cap to remove this cap when a hand is heads-up.
If so, what happens in a situation where we reach the river (in a flop game like hold'em) and the nuts is on board (for example a board of T♣J⋄Q♥K♠A♣)?
Does the betting remain uncapped in this instance and if so, how is this handled in a tournament situation, where calling behind as last to act on the river with the nuts is a punishable offense (due to the potential for soft-playing)? Are we obliged to sit and wait for the two players to get all their money in, one bet at a time, or should a TD faced with this situation rule that as the nuts were on board, no penalty is due? Is there any explicit mention of this situation in any published or widely accepted rule-set like TDA or similar?
I'd hope that if any player was dumb enough to call a floor on someone for calling behind in this situation, any decent TD would rule no penalty, but I'm just curious if this is documented in any TD rule books anywhere, or if anyone has first hand experience with such a situation?
I suppose the same question could be applied to PL or NL games, but there it's very easy (and not as time-consuming) to avoid calling behind with the nuts, so it seems like it would be less of an issue.
