Chet,
I'm not trying to implement a "cap" rule, I would like (the dealer) to be able to announce to the table that all players, holding the correct number of cards when the river card is placed on the board, split the pot. That's all. Move on to the next deal. I actually feel that it makes more sense to use it in a tournament, more so than a cash game. Imagine, a limit game down to two players, going back and forth raising each other in increments of 10 chip wagers. It is not a major issue, that's for sure, but it is more logical (to me) than some of the other topics that have discussed on the forum.
I think it is more "ethical," to save any player the embarassment of folding a hand in that situation. I was dealing in a (cash game), about ten years ago where this exact situation occured. The game was hold'em $10/$20, and on the river I put a "ace high straight rainbow" on the board. I still remember how uneasy I felt when the gentleman that was running the game, bet into a new player and he laid down his hand. It's just one of those situations that I think of from time to time. About two hands later, the guy that initiated that wager actually gave the player the equivalent of half the pot. Unfortunetly, I guess the damage was already done. Just one of those insignificant events that stayed with me. I'll never forget the look on that guys face when he realized what he did. Oh, he never did return to that game.
