Game is 3/6 live. Very passive, sticky, not too loose table. Passive: Very few raises preflop by anyone other than me. If someone raises me on the turn, I can basically read their hand. People checking down solid winning hands on the river. Looks like people trying to get the high hand promo. Sticky: Lots of calling down bets heads up with middle pair good kicker or top pair weak kicker. Not too loose: Average of about 4 to a flop, but also at least one chop of the blinds per hour. 6-7 to the flop pretty rare.
I apologize for the lack of specific details as I am working on remembering live hands more accurately.

Got TT three times in this session, once from LP and twice from MP.
LP hand: two limpers to me, I raise from button. SB folds, BB and limpers come along. Four to the flop.
MP hands: 1(or 2) limpers to me, I raise. Similiar action about 3-4 to the flop for a raise.

How aggressive should I be getting on these kind of boards:
Flop 1 A 4 6
Flop 2 K J 3
Flop 3 78 4

I am looking at most of the table playing preflop: any ace, K9o, QTo and up, and all suited connectors up to two gappers(to hit the st8 flush for the high hand), etc.

Flop 1 and 2, I bet when checked to me, but then shut it down if I got multiple callers and the turn didn't help me.

Flop 3 I bet out, and fired another barrel on the turn to a non-spade.

I had a nice session over all, but I left thinking I was too passive on these type of hands.

Appreciate all the insights on this board. I enjoy reading it daily. Be well.

hands 1 and 2 id just keeping betting flop/turn until someone told me my hand was no good. id check back the river though without a set because a worse hand wont call 3 streets. you could also get lucky and get a old nit with a jack to fold to a turn bet in hand 2.

hand 3 bet all 3 streets unless something really gross comes like an Ace on the turn, in which case check back the river.

in LHE basically though you keep betting until someone tells you your hand is no good. sometimes you lose but usually not. its really hard to make hands in hold em so dont give anyone credit.

also one of the most profitable bets in hold em that people dont make is when you have top pair or an overpair on a three flush board on the turn. everyone will call with a single card of that suit and pay you off. sometimes you pay off a flush but not very often.

I'd be a bit more bold on flop 1 as you have second pair instead of third pair.

Flop 3 even a spade turn you should still fire as many worse hands that aren't flush draws are calling flop.

Flop 1and 2 check call or bet when checked to.
Flop 3 bet 3bet. Call down a cap.
