Of course it depends like everything I didn't so much ask the question as were hoping for some kind of discussion on the subject. What I meant (and this is much more valid for the late phase of tournaments) I see people doing it much more often and being more profitable in these final phases with these tools than I would like for myself.
for example I have sample of 120k hands where my 3bet is about 6 % and within that I have like 20k hands where I have played more aggressively with about 21% PFR and still about 10% the most 3betting. Many keep statistics such statistics ...
Fair enough, let's have a discussion then. In the late stages of a tournament every hand you play is like walking through a mine field. Most raises will get through, especially when your close to the money so when you face a 3 bet it's usually from a real battle hand. But some people are very good at recognizing obvious steal situations and are ready to pull the trigger on a 3 bet when the right conditions arise. Let's go over a few of those conditions.
The most obvious time to 3bet is when someone is raising light and the most obvious time for that is when they're on the button. When you 3 bet or re-steal you have to expect a call from the original raiser who's in position and will often be to embarrassed to just fold outright so your plan has to be to continue on any flop. If you're going to get called anyway then you might want to keep the pot small and just click it back. There's no reason to bet the farm, if he was raising light he'll call and usually fold to any sized CBet but some of of the time you're going to get called. What then? If you're not confident in your post flop play then your better off not even opening that can of worms, but it's good to at least start with a hand with some decent
equity.
Another thing to keep in mind is stack sizes. If you're under 15bb's you're 3bet needs to be All-In. You just don't have enough in the tank to fool around with any post flop shananagans.
The 4bets are really about putting yourself in the other guys shoes. You open raise from the button. If he's a good player he knows that you're often raising light and therefor 3 bets light. You take a deep breath and 4bet putting him to the test. This scenario happens all the time and has little to do with either of your cards. It's a game of chicken. Again, stack sizes are imperative. The idea is to win without a showdown. The only time this can (should) happen is when effective stacks are deep enough so that one of you can find a correct fold. Otherwise you'll find yourself getting called or shoved on by some pretty surprising hands.
This is some pretty gruesome stuff but it should take you way beyond your 6% 3 bet range. It will also do wonders for you're table image when you get away with it. You'll get called names and people with write nasty notes about you, but they won't **** with you.
