Here is my analysis hope it helps:
Hand 1-3 is fine....you can go ahead and fold, keep in mind with HU you are building an image to steal when you don't have cards and chances are the aggressor will have to give you credit for a hand.
In this scenario the aggressor is playing small ball he is trying to see if you will put up resistance. Everytime you fold he is getting more and more confident that he can run you over.
With players like this I like to play possum, because what I like to do is give them the false sense of security that he has +edge on me. Now with this in mind I am looking for a flop like hand 5
Hand 5 is where you make your move. You have established 2 things:
1. This guy is playing very fast looking to accumulate chips
2. Your range will be smaller than his so you can get away with steals on co-ordinated boards
With hand 5 when the flop comes JJ4 and you have K3 and he bets the flop, I float here for 1 bet. This does two things:
1. Lets him know I have a hand (surprise I don't but he doesn't know that...lol)
2. I have position so I am going to take it down on the turn because my call on the flop represents I have hit the board. In this case the villian has not JJ4 he checks a J on that flop because he is bluffing every other one. What ever hits on the turn if you are checked to you have to fire out a pot sized bet.
Now the reason you fire out a pot sized bet is it increases your "weak tight" image to "I only play a pot when I have a hand and I have no clue what you have and I am scared of my hand so I am betting a monster"
Wash, rinse, repeat that formula

You will eventually trap him because there will be times you float him with a monster and when you do, you check the turn (because your range is way better than his) and the river you smash it. And the other times you float with nothing you still take down the pot on the turn because most of these guys heads up will not double barrell unless they have a made hand.
Now for hand 11
hand 11 :

This is incorrect on many levels. J10 is losing to any Q,K, A or PP....his all in move is typical aggressive play....he has run over you so much that he figures now if he increases his bet and starts shoving you will call with any decent cards.
Don't fall into this trap, most aggressive opponents will do this 3-4 times max and then get frustrated because you are folding. The idea here is wait for him to go back to his min-raise flop bets and then pound the flop and put the pressure on him.
I don't like calling all ins by maniac players unless I have a PP or at least AJ-AK.
Hope that helps
