Hey everyone, couple recent JJ hands that was wondering if I could get your input on?

1.) Villain: 35/6/0 over 17 hands, no specific reads but seemed to be a bit of a station

Need help/advice on the turn and river on this one...

Button ($1.95)
Hero (SB) ($9.50)
BB ($10)
UTG ($8.55)
MP1 ($3.80)
MP2 ($9.85)
CO ($5)

Preflop: Hero is SB with J, J
1 fold, MP1 calls $0.10, 1 fold, CO (poster) checks, 1 fold, Hero bets $0.60, 1 fold, MP1 calls $0.50, 1 fold

Pretty standard here, 5xbb raise over limper

Flop: ($1.40) 6, 5, K (2 players)
Hero bets $0.80, MP1 calls $0.80

C-bet little over 1/2 pot (perhaps this should have been bigger), villains range is still pretty wide here

Turn: ($3) 4 (2 players)
Hero checks, MP1 checks

I am probably w/a or w/b here (beating 5x, 6x, small pp, losing to kx and sc that make a straight)
Thinking the 4 doesn't hit much of villains range (only a straight or a loose 44)
I checked to keep pot small, setting up for a bet on the river, should this be a raise?

River: ($3) 7 (2 players)
Hero bets $1.50

My thought was to B/F thinking that 3's and 8's are not likely here and K probably would have bet turn
Would c/f or c/c be better?

2.) Villain is 43/26/8 over 46 hands, pretty active PF and playing alot of cards

I had been looking for a nice hand to value-town this villain and this one seemed to be a nice opportunity

Comments on turn/river?

SB ($2.30)
Hero (BB) ($10)
UTG ($12.35)
MP ($12)
CO ($1.75)
Button ($8.15)

Preflop: Hero is BB with J, J
1 fold, MP bets $0.30, CO calls $0.30, 2 folds, Hero calls $0.20

Just call to keep worse hands in

Flop: ($0.95) 2, 5, 8 (3 players)
Hero checks, MP bets $0.40, 1 fold, Hero calls $0.40

Good flop for Hero, put villain on really wide range at this point (overpairs, overcards, suited & non-suited connectors) and think i am well ahead of most of it
Call 1/2 pot bet for value, choose not re-raise b/c only better hands

Turn: ($1.75) 3 (2 players)
Hero checks, MP bets $0.90, Hero calls $0.90

Call 1/2 pot bet again for value, think I am still ahead of range here

River: ($3.55) 5 (2 players)
Hero checks, MP bets $2.80, Hero ???

Good size bet on river (80% pot), was thinking this could be 5x hitting, 46, 2 pair but could also just be a spewy bet, the size really made me worry
Need 30% equity to call, is this a call or fold? (raising out me thinks)

3.) Villain is 29/5.8/1.03 over 224 hands, hasn't shown down much so don't have specific reads

Thoughts on how to react to the villain min-reraise on the flop?

Is this an obvious fold or is this SD/FD/Air often enough to re-raise/call shove?
