Villain is totally unknown. Only 6 hands on him and he hasn't played a pot yet.

This probably too easy for you guys but this hand confused the hell out of me.

PokerStars No-Limit Hold'em, $0.25 BB (5 handed) - PokerStars Converter Tool from FlopTurnRiver.com

saw flop

Button ($14.34)
Hero (SB) ($25.18)
BB ($25)
UTG ($25.67)
MP ($30.10)

Preflop: Hero is SB with Q, A
3 folds, Hero bets $0.75, BB calls $0.50

Flop: ($1.50) 2, A, 3 (2 players)
Hero bets $1, BB raises to $3.60, Hero ???

Seems like raising in this spot only folds out worse and more often get shoved on by better.

Call or fold? If we call, what's our plan on turn and river?
