Came across this situation last night as was totally stumped as to the size of the 3bet I should make. I was afraid that if I bet too small then each caller effectively prices in more callers and I'd be out of position. I've since thought that If I'd just shoved , it could have looked like I was trying to steal the pot and may have got some callers who may have folded to a standard 3bet situation.It was the number of callers that stumped me.
