In my opinion a LAG player has more opportunities to bluff.
If you present yourself to the table as someone who can play all different types of hands in all different positions you will find that a bluff will work in a couple different ways. First of all, since your range of hands is a lot higher than the average player, the potential for hitting a flop with a rag board would seem to be higher. Be careful that the players you are sitting with are the type that can lay down an over pair to a raise and a re-raise, some just can’t do it and you have to pick your spots, making the same play can pay dividends against one player, and break you against another.
Imagine a late position raise for a tighter player (you put them on AK) and you calling from the small blind with 35 offsuit, flop comes down 35K and you check to the raise who fires at the pot, you pot it a bet and they re-raise, you pop it another bet and they? what? are they going to push here? lay down? you are a 7-3 favourite here and don’t mind the push, but for the future you need to know what he is going to do here. Do they just call and hope to see and Ace come down also? Another K?
How about on a K33 board? do they think two pair with top kicker is a pushing hand or are they worried about the 3? If they are the pushing type, use your implied odds on these flops and get paid, instead of bluffing at them when you hold JQ or AJ.
I wrote before that I think many people play AK too strong, after the flop all you have when you miss is a pair draw really. Getting people to lay down AK can be tough, but putting them on the hard and firing at every flop that misses it with a LAG image can pick you up a lot of pots.
The advantage to making some bluffs on these hands, try it on small pots that won’t kill you to get looked up on, is in the future, you can make the play on hands with the goods and get paid off, but in order to make money long term when bluffing you have to know that the player is the type that can make a tougher lay down.
