Final Pot: 14 BB

Table is fairly loose, 4-6 people to the flop.

Reads :

MP2 is a little tight, and semi-aggressive. He has shown down top pair with a decent kicker a few times.

SB is fairly loose, plays a lot of hands and shows down with top pair, crappy kicker or even less then top pair sometimes.

No other reads.

I am curious how my play is. Preflop I limped due to position and the fact that its a loose table. When the flop hits and I have middle pair + a gutshot straight draw I figured it was a fairly strong hand.

When the turn hits as a blank for me, I slow down a bit but figure I have some good outs and the pot is fairly large by then.

The river is standard for hitting my trips, I was not worried about a runner runner flush in this instance.

Did I play this correctly or was the flop raise too aggressive? How would you play the turn?
