3bet pots are one of the toughest things in poker, post flop, that's why i think so many regs depend on just 3/4 betting like crazy preflop because they basically dont' want to see flops.

i would say at the beginning we're better off just 3betting for value from the blinds vs LP openers, if you think they are wide do it with 99+ and AJ+ maybe even some KQs type hands. skip the Axs and sc type hands for now.

in general you want to cbet Q, K or A flops that aren't too connected. a ton of people love to flat 3bets from LP with hands like suited broadways, pairs and Ax type hands.

example: BTN opens he's like 22/18 and doesn't 4bet crazy, you 3bet for VALUE with AJs, flop comes Q73r and you bet... if turn A you gotta keep firing, if it checks down and he shows you a hand with value say 88 then make a note and you can barrel this person next time because it's so hard to continue in their place.
