Can I slowplay now, please?

[ticks]

I flop a boat, and decide to slowplay the hand.

Reasons:
1. SB is laggy, and has produced some pretty mindless aggression in previous hands. I want to give him a chance to fire at the pot. The others are unknown quantities.
2. The chance for someone making a second best hand is good. QT, 78 and KQ can make a straight. Turn produces a flush draw.
3. The chance for someone outdrawing me is low. If someone has the last 9 and a Q, K or A they have 3 outs.

What would you do different?
