Hi
Let's make some assumptions here first.
1. Villain is never bluffing
2. He would value raise 2pairs.
Let's assume that villain is limping around 30%-40 of hands here. OR maybe he raises the top 15% and limps the next 15%. I'm not exactly sure, but we'll exclude hands weaker than the 60th percentile.
Possible hands in villain's raising range:
T9
A7
87
J7
Pot odds offered to you: 2.75/8.25 = 33%

2. Conservative

Equity Win Tie
MP2 78.26% 69.57% 8.70% { A7s, J7s, T9s, 87s, A7o, T9o }
MP3 21.74% 13.04% 8.70% { Ac7s }
3. Middle
Board: Jd8hAs3s7h
Equity Win Tie
MP2 66.67% 59.26% 7.41% { A7s, J7s, T9s, 87s, A7o, T9o, 87o }
MP3 33.33% 25.93% 7.41% { Ac7s }
It all depends on how many combos of T9 you're willing to give villain. I think he would often bet the Flop with the draw so we could probably further discount that from his range. I guess there's another combo of 77 that we lose to, and perhaps 33 being played weirdly.
I think it's extremely close, I'm kind of torn between either option. You can probably call and feel ok about it, probably close to a breakeven decision.
