Difficult situation

This is the first hand in a very long time that had me lost at what to do - I think the key decision is when opponant 4 bets the flop - do I call,raise or fold? Also im not overly keen on my flop 3 bet.

Opponant is 48/24/1.57 - agg factor of 4.83 on the flop - This is the first time ive played with him and seems to like trying to outplay people and makes a lot of moves - though this observation is only over ~100 hands, although with the small 4 bet on the flop im almost positive hes not just making a move. I'm sure he views me as standard TAG

At this point its $701 to me to call and I have ~$1800 behind

edited the raises to make it easier to follow

I'm not following the flop action. A raise to $1,401 wouldn't be a legal raise or if it was a raise of an aditional $1,401 then there wouldn't be $1,800 behind.

You are in a tough spot because your 3 bet is too small.

You still can't consider folding here, right? You are getting 1 to 4.5 pot odds, which is certainly enough to call with your hand. A fold here would only be right against a made flush, which looks like only a small part of his range here.

If you call on the flop, then you will be getting the right odds to call on the turn as well (at least 1 to 5). Because of that you seem to be pot committed already, so why not just push?

i push here usually but thats probably a mistake if you dont plan on using the image it gets you
