Middle set - 3/6 BM

[Biggle10]

Hero has 6 [img]/images/graemlins/spade.gif[/img] 6 [img]/images/graemlins/club.gif[/img] in UTG + 1.
Limped around to Loose passive in the SB who raises. I would probably call SB loose passive, but he's relatively new to the table. Everyone calls.

Flop: K [img]/images/graemlins/diamond.gif[/img] 6 [img]/images/graemlins/diamond.gif[/img] 2 [img]/images/graemlins/heart.gif[/img]
SB checks. Hero bets. Old man in MP (who plays stereotypically like an old man) calls. Beginning player on the button raises. SB 3-bets it. Hero 4-bets. Old man calls. Button calls. SB 5-bets and caps. The 3 of us call.

Do I slow down on the turn: if the turn is a diamond? the turn is a blank?
