Blinds are 30 / 60

I have 60 bbs.  I am dealt Kc10c on the high jack.  Folds to me, I raise to 2.5 bb.  Button calls.  SB calls for 2bb more.  BB folds.  3 players.  Pot: 510

Flop:  5hJcQc

Monster flop for me, open-ended straight flush draw.  SB decides to weak lead with a bet of 180 into 510.  It could be a fish bet holding two pair hoping for a raise, but my read of Q with weak kicker is later confirmed after I raise.  My hand is very strong and I want to either play it fast on the flop and get all my chips in or hopefully make a weak Queen fold.  I raise to 680, 500 oo top.  Button folds.  SB simply only calls the 500 more, instead of re-raising, which screams weak Q or a draw.  Pot: 1,870

Turn:  7h

Clearly I miss huge here on this card, but my story would logically be that this is a great blank that keeps me ahead and strong from the flop.  SB checks to me.  I bet 935, half the pot.  The SB simply calls which is perplexing to me.  I'm thinking why would a weak Q call for so much, unless the turn gave him a heart draw.  The club draw is overpaying.  Either way, I'm happy with simply the call.  I figure if I river a K, my hand is best.  Ace gives me the straight.  9 the straight.  Any club I have the flush.  8 or below, I can fire yet again and likely get the weak Q to fold.  I like being in position here.

River: Ah

SB thinks this is a bluffable card for him.  He pushes all in.  Woops.  I snap call with my straight.

Should I have better any larger on the turn?  Would a smooth call and then raise on the turn been a better play?  Always looking for constructive feedback.

Thanks a lot.
