Lets say I'm on the button with 1 limper and I raise 3x BB with pp 9s. SB and BB fold and limper calls. So I am putting him on a draw. Flop comes (8h2d4s) He checks...So what would be the correct bet here to try and knock him off his draw(3xBB?) Thank you
I'm not sure what you mean when you say you're putting him on a draw, because I look at that board and I don't really see any draws.
Anyway, I'll tell you in general what you should do against draws in terms of bet sizing. Lets say you have AJo, and flop is AsJh6h. You figure you have the best hand and you're wondering if he maybe has 2 hearts, so you want to bet an amount that makes drawing for him unprofitable. Lets say pot for now is $12. If he has 2 hearts, and 2 are on the board, that means there are another 9 hearts in the deck. The odds of him getting a heart on the turn are about 4.2 to 1 (its very easy online to find tables that give you odds for drawing hands, for example straights or flushes, in case you don't know how to figure them out, if you need to find one let me know I'll help you out). Since his odds are 4.2 to 1 for a flush, you need to make sure you bet enough to give him incorrect odds. Pot, we said, is currently $12. A bet between 1/2 and 3/4 pot is enough to make drawing unprofitable. A $9 bet, for example, will make the pot $21, so he has to put $9 in a $21 pot, which means he's getting a little more than 2 to 1 (2.3 to 1).
You should, though, get familiar with the concept of implied odds. I suggest you give a good look to the articles section of the forum, you will find many interesting articles about odds and implied odds. Give a look at it and if you need more help just post in the strategy section and we'll help you out.
