I feel like I can consistently beat 10NL and am now properly rolled for 25, but before I move up there are a few leaks i feel should be plugged.

C-Betting

PokerStars No-Limit Hold'em, $0.10 BB (5 handed) Poker-Stars Converter Tool from FlopTurnRiver.com (Format: FlopTurnRiver)

BB ($1.80)
Hero ($30.25)
MP ($16.60)
Button ($9.85)
SB ($5.85)

Preflop: Hero is UTG with Q, A.
Hero raises to $0.4, 1 fold, Button calls $0.40, 1 fold, BB calls $0.30.

Flop: ($1.25) J, 4, 3 (3 players)
BB:Checks
Hero




Is this a spot to continuation bet even though I flopped air? If so, how much? What if I had position on both players? Or is the C-bet best reserved for HU?


Completing from the SB

It seems my range should be wider completing from the small blind in limp pots simply due to Pot Odds, but also makes it tougher to play hands oop. Any suggestions on a range to be completing? I feel like thats a huge leak when I complete small SC's, Axs, Axo, JK, small pairs, then flop a mediocre hand and have to play TP, flush, and straight draws out of position. Trying to tighen up both aspects of my game and quit bleeding so much money on plays I feel should be profitable.
