agree with the general opinion of
"take the chips you spent raising the flop and instead use those to raise preflop". You called 180 and then raised to 1275. So you've already committed 1,455 to this hand. Had you simply raised to about 900-1,000 preflop it would have been CHEAPER and actually given you more information about the strength of villain's hand. (if he calls a big 5x preflop 3bet he has something, but your flop raise is only a 2.3x raise, which is relatively small for him to call if he has anything. and if he has ANYTHING you are beat. preflop, you could actually beat some of his hands he might call with like AK/AQ. now, you'll beat essentially nothing when he calls).
Now....if you elect to flat with JJ preflop you must understand what you are doing and have a plan. You are essentially set mining. meaning you don't continue post flop without a set. On this flop you should just fold. 2nd best option would be flatting...but it's a distant 2nd. Only reason to flat is to just hope he's
bluffing or overvaluing a hand we beat and just call him down if overs don't come. I think that's a bad plan but it's much better than raising. Raising is just suicide. you're now bluffing with JJ. When he calls your bluff, he has something and you're beat. turn is an easy easy fold.
Here I think is what you could do to most improve your game moving forward:
Everytime you put money into a pot, understand WHY you are doing it.
ask yourself:
is this a value bet? then there must be worse hands than me that can also call this bet.
Is this a protection bet? then there must be hands that I am currently beating that have good
equity to outdraw me.
Is this a bluff? then there must be better hands than me AND I think I can get them to fold to this bet.
Am I on a draw and getting the right
odds or implied odds to continue?
Do I smell a bluff and think my hand is strong enough to just act weak and call down? Will I have the stones to call down later?
Betting for information, or to "find out where I'm at" has been basically debunked by nearly all good players as a bad logic for putting more money into the pot.
