quick question

Depends on their postflop strategy. I would recommend you have a plan for the entire hand before making any decisions preflop.

I don’t know that’s exactly true, but you should attack wide openers. How you get in the pot with them is maybe less important, but you should upgrade thin value and attack them when you have it.

Same with calling down, if they start betting, be more sticky than normal. They come in different versions, so until you have a handle on their play, don’t necessarily get out of line because they play too many hands.

So no, I don’t think you change your plan. It’s more like when this guy gets in the pot with you, your range is much stronger. You keep that in mind as play unfolds.

And remember, the other players also factor into any move you make.

In general my 3-bet range expands a lot against people who open wide. However, if i am in a blind I tend to not want to play a large pot OOP against them especially if they are calling my 3-bets when I am in position. So when I am in the BB my calling range expands and I typically won't expand my 3-bet range.

As far as calling tighter that depends on position. I probably call wider on the BTN. But in part that depends on how aggro the blinds are.

I think generally you can 3-bet more, although you don't necessarily need to flat tighter. A few things I would think:

-If villain opens too wide and overfolds to 3-bets, I would definitely 3-bet a lot more often.
-If villain opens too wide, defends adequately to 3-bets, and is good postflop, I would 3-bet more often than is standard, and err on the larger size. But I'd be careful if villain is good enough to notice and adjust by 4-betting more often.
-If villain opens too wide, defends adequately (or too widely) to 3-bets, and plays poorly postflop, I'd frequently 3-bet a smaller size to isolate but to encourage a call.
-I'd flat sometimes if I was on the button and the blinds weren't aggressive about 3-betting, with hands that flop well, more than hands with sheer raw high-card equity.

Generally, we want to play more hands against players who are making mistakes, so they can make those mistakes to us. Also why we're adjusting in a way that gets it heads-up with a bigger pot with us in position more often.
