Was playing a 5/5 live cash game the other night. (aggressive game, was played more like 5/10)

8 handed – Im big stack at the table with about 2k…everyone else is fairly deep as well.

There was an UTG straddle for $15, im UTG +1 with 10's. I make it $40.

Get flatted by cut off and flatted by SB (BOTH PLAYERS VERY LOOSE AND FISHY). POT: $145 

FLOP: 9 3 6 rainbow.  SB checks, I bet $75. Cut off flats, SB shoves for $275 total. POT: $570

SB was playing very splashy and fishy, so I knew for a fact he's shoving all his 9's and any of his straight draws…especially the open enders:     4 5 and 7 8..

I also wasn't worried about the cut off flatting my C – bet because he also was playing splashy and fishy and he could very easily have flatted me with any one pair on the board…even a pair of 3's for bottom pair…(that's how bad he was playing)

So I decided to make the call of $200 more feeling pretty confident with my overpair of 10's. The cutoff snap calls the $200 as well…lol…so now im obviously worried about my hand…POT: $970

The turn is an Ace: So the board now is 9 3 5 A…I check feeling there's no reason at all to bet at this point. I don't feel that I have the best hand anymore after he snap called the extra $200. I doubt he just has one pair of 9's at this point. He bets $200 into the side pot (with $500 behind in his stack) The only hands I feel I can beat at this point are like 79, 89, 910, ect… But I just figured there is NO way he's betting there with those hands and he would just check down for showdown value.

So I fold. He ended up turning up Kings, smooth calling pre-flop AND on the flop to a bet and a shove…lol…seems real bad, but whatever. And the SB turned over 9 3, flopping two pair…lol.

So, just curious on everyone's thoughts if I lost the minimum here or could have played it differently?  Thanks.
