Hand from 'How Good is your Limit Hold'em'

[mack848]

I disagreed with the answer to this question and the reasoning behind it given. I'm interested to find out if it's just me. In general this book is very good IMO.

Players are generally loose. BB appears to only take notice of his own cards.

Hero has Q6o in SB.

4 limps, Hero calls, BB raises, 4 calls, Hero calls
(the author recommends folding to the raise, but continues the hand with Hero calling).

6 to the flop of Qh Qc 4h (12sb)

Question is, does Hero go for the check/raise, or bet - and why?
