25NL line checks

Exact hand histories later......

Hand 1.

Villain is moderately tight and certainly not out of line.
1 limped, I raised to $1.25 in LP with KcKd, BB reraised to $3.5, limper folded, I called.
Board T45 all spades, pot was $7.35, BB bet $5, I pushed all-in ($19.4), BB has me covered.

Hand 2.

I open raised to $1 with T9 on the button. Both blinds called.
Flop 478 2 hearts. Both blinds checked, I let this check through.
Turn 6 non heart, SB lead 0.75, BB raised to $3.25, I overbet pushed. I had both players covered, SB has $19 behind, BB $16.

Hand 3.

I open raised to $1 with TcTh UTG. 2 callers including BB.
Flop 993 2 spades, BB checked, I bet $2, LP called, BB folded
Turn 4 non-spade, pot was $7, I checked, BB bet $2, I check-raised ~ to $12 putting him all-in.

Hand 4.

I checked with 73 spades in BB.
4 players, Flop Kc6d3h, all checked.
Turn 3d. Checked to button who bet $1, I check-raised to $4, MP cold-called both bets, button folded.
River 6c, I checked, MP pushed his remaining $10, I called.

they all look ok to me

Hand 1 Villain had QQ with Qs, and he turned the flush.
I didn't like reraising/pushing preflop, coz it would allow QQ/JJ/TT to get away cheap. Would anyone play differently?

Hand 2 I was able to get BB call with K5d. Could a better player get away?

Hand 3 LP called my check-raise with 77 and didn't improve. I was content to pay off a 9 against a shortie, and I was also content to push away FD+overcards and win the pot as it is; I'm just lucky enough to get a donk call me with 2 outs. Are my thoughts okay?

Hand 4 LP had AJd and a busted FD -- what an easy bluff to pick off. I don't think a 6 is not taking a stab on the flop and then cold calling 2 raises on the turn.

these all seem fine.
