25nl, Unknown, what's his river b/c range?

Villain is unknown <10 hands, but 1/2 stacked and his flat certainly argue that he's most likely bad. Fairly stnd open I think, seems like a decent board to c-bet, and just shutdown to anything but a fold obviously, but the question is, what is villains b/c range on the river? More than that, what's villains PSB/c range?I mean obviously all his nut hands, but does he call enough w/ random shit and A's to make this profitable? The flop call was c/insta-call.

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

MP ($24.45)
Hero (Button) ($28.65)
SB ($12.65)
BB ($20.55)
UTG ($16.20)

Preflop: Hero is Button with 7, 6
2 folds, Hero bets $1, SB calls $0.90, 1 fold

Flop: ($2.25) A, Q, 2 (2 players)
SB checks, Hero bets $1.50, SB calls $1.50

Turn: ($5.25) 6 (2 players)
SB checks, Hero checks

River: ($5.25) 7 (2 players)
SB bets $5, Hero raises to $26.15 (All-In)

Given his stack size i think this is fine, his range contains more top pair hands than hands that beat you and he certainly isn't folding them.

Board: Ad Qc 2c 6d 7s

Hand 0: 52.941% { 7d6h }
Hand 1: 47.059% { 77-66, 22, AQs, A2s, AQo-ATo }

this is a very pessimistic range, and he could probably call with like A3s-A9s as well, may fold 77 and 66 on the flop, etc.

ohh yeah thanks. Obviously he showed up w/ something that beat me, doesn't matter I'm well aware, but had he mucked I don't think I would have second guessed myself.
