Sample sizes aren't really helpful, it's the first time he's 3bet my cbet so reads are sort of non-existent apart from basic HUD stats. No showdowns of note.

PokerStars No-Limit Hold'em, $0.10 BB (9 handed) - PokerStars Converter Tool from FlopTurnRiver.com

saw flop

BB ($8.31)
UTG ($22.59)
UTG+1 ($29.40)
MP1 ($9.02)
Hero (MP2) ($36.18)
MP3 ($11.14)
CO ($11.79)
Button ($23.53)
SB ($20.48)

Preflop: Hero is MP2 with A, K
3 folds, Hero bets $0.30, MP3 calls $0.30, 3 folds, BB calls $0.20

Flop: ($1.13) 4, A, 8 (3 players)
BB checks, Hero bets $0.70, MP3 raises to $1.50, 1 fold, Hero ???

Ranges etc -
BB lol any two
MP pf flatting range - 22-JJ 78s+ KJs+ ATs+ AJ+ (though probably not AK)
MP flop raising range - 44 88 AJ+ A4 A8

These ranges realistic?

Just basically a line check with this one, simply because it's a common spot that I don't really know what to do in. All three actions come to mind. Folding seems nitty, calling seems stationy and raising seems spewy. What to do?
