This is my way of thinking if I decided to bet.
Okay 3x BB
We lead say 2/3 of the pot... If he calls we still can hope for a gutshot if he calls then most likely we are going to need a lot of help.
Sometimes I find if a player just keeps flat calling it means he's weak or he thinks ur a fish.... So you have to think of your table image and how well your playing.
If you've had some decent hands and made good plays by leading out every street we put the pressure on our opponent but also it tells
us if he ain't scared, we should be.
But also you said the tables been awfully tight. All of a sudden he's not scared to throw money out there???? ... Why!... Either your drawing to the nuts or your being the fish at the table.
we were really after the 9 after the turn especially on a tight table... We are going to be up against someone with something or thinks he has something.
Anyways If you want to get more creative at least go Button or Cut Off (Becareful who's the button though)
