People!!! When a player is all in and there is a side pot between 2 other players it makes no sense to bluff the other player out of the pot! You have to show your hand to win the main pot so unless you have a hand WORTH betting and creating a side pot check it down and knock the all in player out. You betting with Ace high makes zero sense when the all in player is gonna win with a random better hand like 33, maybe let the other player in the side pot beat the all in player.

Now if the side pot is substantially large or better yet larger than the main pot by all means play poker and win your pot! Otherwise FREAKIN check!!!!@$@$?&)!!
