small problems

- your hand above, 3b preflop
- why do you include 99-KK in his raising range when there is an A on the flop and you just donk bet into him? You think he is bluffing?
- why do you think he could not have the flush on the turn if he had all the flush combos on the flop?
- why do you think of going all-in on the river? If you want to go all in anywhere in this hand, it should be on the flop. The hand of your opponent did not get any weaker since the flop, and yours did not get any stronger. If you think he really has that many flush draws and that many weak aces in his range and stuff like 99-KK, and that he is going to call if you 4b on the flop, then you should raise (not necessarily all in yet, but raise). On the contrary, if you think that he only raises your bet on the flop with AK or AQ or AJ, then you should fold.

Most of the time you should bet, raise or fold. Calling should be the less frequent of your actions. DO NOT CALL BECAUSE YOU DON'T KNOW IF YOU SHOULD BET OR FOLD. JUST MAKE A DECISION.

When you bet or raise, always ask yourself why: there are only two reasons:
1) for value when you think your hand has a better equity than that of the calling range of your opponent.
2) as a bluff because you think he might lay down a hand better than yours.

If these conditions are not met, then most of the time you should check or fold. One scenario in which a call is correct is when you are facing a bet or a raise and you think your hand is better but your opponent will probably NOT call if you raise, or when you think he has the better hand but you have a draw with good implied odds. Then calling is an option.

Generally at the micros, you almost only bet for value.

"Using fold equity" is bluffing or semi-bluffing. Generally you should only try that against tight players, or good players who are capable of laying down a good hand when they feel they are beat.

Keep trying and practicing putting your opponents on ranges. It is more an art than a science and it needs work and practice. Do it every time you play and after you play when reviewing your hands.
