Villain is defending 2/5 of my 3bets. In general, I have trouble figuring out when I should fire 2 barrels OOP in 3 bet pots.

3 bet for value. I don't know why it says raise to 1.75. I made it $2 to go.

I elect to continuation bet. I know you are suppose to continuation bet but I really have no rhyme or reason behind these type of situations. What type of thought process should I go through in these spots. Or rather, in 3bet pots in general?

I have a gutshot and K high flush draw. The more I think about it I feel like I should have barreled here. But my thought process on why I should or shouldn't is weak.

Now when he leads for half pot should I reraise or just call. I elect to call and I'm not quite sure what is the best line to take. I have no reads on whether or not villain has been floating and trying to take away the pot so I'm not quite sure what range of hands he has that will call 3bet pre, call flop, then lead turn for half pot when checked to.

If he had a strong hand wouldn't he lead bigger to protect against the third spade coming?

River I feel like I have showdown value against some of his random floats with my K high and so I elect to try to check it down.
