I don't think your turn call was too loose. Maybe it was if you look at straight up Pot Odds 9:4.5 or 2:1, but the impiled odds adding in his $20.20 left in his stack 29.20:4.5 giving you about 6.5:1. You don't just have the possibility of a boat, you have a possibility of a fourth 7. So your outs are 3Queens, 3Tens, and 1 Seven, 7 outs. There are 46 cards left so your odds of making your draw are 39:7 or about 5.5:1. So you were better than even money on the call, so too loose? Not in my opinion. Nicely played.
