I usually play a fair bit looser than the other regs at my table, around 27/24 and I find that they tend to get really frustrated and not give me any respect (which is the plan) the big thing when playing like this is to try and anticpate when your opponent will 'snap'. Sometimes you can just tell they are getting frustrated and you know they are going to reraise if u raise - so 4 bet them and they get so angry, it's difficult to reply to these hands as so much of what the corredct play is, is based on your opponents emotional state/how frustrated he is getting.

Hand 1 - I like this, from my experience, when somebody cold calls your 4 bet preflop when they are slightly frustrated it is usually an AJ/KQ hand which they call with the intention of raising a lot of flops, that being said i really like your cbet size, and I do the same - 1/2 pot into a 4 bet pot to give them some room to make a mistake by attempting to make use of their percieved FE. If you are beat - then oh well, more variance is the price you pay for playing more LAG.

Hand 2 - Again I like this and would play it exactly the same as you - if you get called just give up, this is really good for balancing the times you have 22/33

Hand 3 - this one is tough, I'm not a big fan of it as you are repping such a small range and generally villains dont believe you blind vs blind ESPECIALLY with a bad image. If he shoves I'd just fold as often your outs are dirty. Although having said that, it does put villain in a really tough spot with a lot of his range.

Hand 4 - This depends on how you think villain is feeling, id probably also make the 4 bet a little smaller to try and get him to shove a little bit more often preflop - and yes I'd usually snap call too.
