This may be an old idea, but since I haven't seen it anywhere I thought it might be worth writing down.
I have wondered why couldn't poker be played so that whenever all remaining players in a hand are all-in, the pot would get split according to the showdown probabilities, without even dealing the rest of the cards.
Especially in cash games I don't see any negative effects from this, although it might change the optimum tournament strategies. And it would be trivially easy for any online poker rooms to implement.
Anybody have any thoughts on this? Would you play this kind of game if it was available?
