Right wrong or indifferent?

I am still struggling with proper sized bets and the whole game in general. I way overbet here PF since I am OOP and really just want to take this down right here. I was surprised BB cold called....but he was a 66/0/0 donk.

PokerStars No-Limit Hold'em, $0.25 BB (7 handed) from (Format: Bet The Pot)

CO ($24.30)
Button ($7.85)
Hero ($24.50)
BB ($9.25)
UTG ($12.10)
MP1 ($19.35)
MP2 ($14.65)

Preflop: Hero is SB with , .
3 folds, CO raises to $1, 1 fold, Hero raises to $3.25, BB calls $3, CO folds.

Flop: ($7.50) , , (2 players)
Hero bets $6, BB calls $6 (All-In).

Turn: ($19.50) (2 players, 1 all-in)

River: ($19.50) (2 players, 1 all-in)

Final Pot: $19.50

You played it perfect IMO.

Re-raising to $3.50-$4 isn't so bad. I like applying a lot of pressure in the blinds to LP open-raises. Cutting down on aggressive BvB confrontations and spacing out your 3-bets randomizes your play with multi-tablers using PT as well others.
