see....for me if
I woulda 4bet light with that A6o and if
it didn't immediately get me a fold, I would basically be done with the hand, unless they flatted and then something magical happened on the flop.
so...for my first attempts at 4betting light I am looking for spots where #1 the pot is heads up #2 I have position #3 I think they are 3betting light, likely because my raise looks like a late position steal. #4 they are not even close to pot committed #5 they are a player who is good enough to fold #6 I have a tight image at the table #7 this player is aware of my "tight" image and capable of adjusting accordingly.
let's take a pretend example:
blinds are 100/200 say it folds to my button and I raise to 500 with
SB Folds, BB re-pops it to 1,300. He has been doing this kinda stuff a lot and he is very aggressive. He has a total stack of ~20k. I'd put his range for 3betting at any Ace, K9+, any pocket pair, Q9s, QT+, J8s, J9s, JT+ and a few random suited connectors.
I 4bet to 3,000 off my stack of about 18k
if he folds, I just picked up 1,400 instead of 300 from winning the blinds.
now at this point, he may elect to just flat because of good pot odds
and I won't really like that too much, but that is why I have position as back up. Pot contains 6,100 if he flats and a Cbet costs me about 3,500....so if I miss the flop he checks and I cbet I'll have nearly 40% of my stack in this pot. gulp....THIS is the scenario that scares me the most...if he check raises the flop I guess I have to fold..and I just lost 40% of my stack by "getting cute"... If he check calls the flop, I'll probably shut down on the turn and he'll bluff the river and I might have to make a hero call if I catch 1 pair or something?....or just sheepishly fold.
if he 5bets preflop I'm gone. I lose 3,000 out of 18,000 so 17% of my stack. I can live with that.
