Hand 2: After losing the previous hand, I don't go on tilt and play str8 forward small ball for a bit cuz I don't want him to think I'm on tilt. But, for a while now I've been thinking his pf raises aren't that well balenced, or as balenced as his limps, because I feel he is more prone to raise garbage and some premium hand pf and limp medium/premium/garbage strength hands.

After seeing more showdown hands since my AhKh hand has really convinced me that I need to 3 bet more preflop. Just before this hand I had 3 bet him w/ K5s, he called and folded to a cbet. When this hand came up on my next button I really sensed that any cbet was gonna get raises. My question is, if I know I'm gonna get messed w/ and all I have is 2nd pair how bad is my shove? I don't think I really thought this through enough. If I think he's bluffing, should I continue to let him bluff? Honestly, my plan was to rebluff w/ any 2 at this point cuz I knew he was gonna raise, 100% certain of that. Did I miss value here? Didn't I just violate the rule that says, if you aren't gonna get a better hand to fold or a worse hand to call, don't raise? Well... I have more to say but will hear what you guys have to say first...

There are times when that rule can be violated. There was an interesting discussion about this in some vid I saw recently (FWF 7?). They were talking about this kind of situation where you rebluff with a hand with sd value.

I think this is fine. Firstly, it's going to be quite hard to c/c this down. There are quite a few turn cards that can come that would make it even harder. Secondly, a flat call here looks super strong so it's doubtful if you get any more money out of his air range anyway. Thirdly, you sensed the raise before it came, and this is the kind of board where a lot of people will just call with their strong hands. So you shouldn't worry too much about being beat.

This was my inclination as well. What am I gonna do w/ any card 6 and above being a scare card except for a J or 9 if I flat his raise? Don't mind my play then... maybe some esle can add to this

I think this is actually very well played by your part.
Villain has to have a big hand to call here which he should have almoust never, seeing that he just called your 3bet and i would assume that he 4bets QQ+ and AK (?).
99 and 66 are possible but they are very rare.
If you have played solid game like you say this would look very strong and it would be easy to put you on AK,AA and he has to play accordingly.

If i were villain i would maybe call with KQ and hate it and fold KJ.
