I'm guessing one of the people you're referring to is
me.
As I explained in my most recent post to that thread, I thought smooth-calling the flop and losing out on 1 SB would make my Villain more prone to calling another bet (or reraising) on the big-bet streets when he was likely trailing very very badly.
And given that he wouldn't have folded his strong hand (trips, but with a bad kicker) anyway, I didn't allow him to stay in the pot to hit that longshot draw when I could have forced him out of the pot. He wouldn't have left.
