KQ...flop check okay?

[JooWish622]

Villian just sat down, nothing intersting so far except that he won a big pot with a big hand recently.
I am playing fairly loose but have shown down good hands
2-4 nl, 6 handed, hero is in CO, villian is in button.
Hero dealt KQ spades, raises to 16, Villian calls 16, both blinds fold.

Flop: QT8 3 diamonds. Hero checks, Villian bets 32, Hero calls.

Turn: 4 clubs. Hero bets 40, Villian raises to 210, Hero folds.

My question: Does this line save me money when I'm drawing dead on the flop and keep me from getting blown off my hand when I'm ahead of hands like (QJ, T9, A of diamonds).

Do you guys like this line to prevent myself from getting raised off my hand on the flop.

Benefits of this line: its hand defining merits on the turn+ getting money when I'm well ahead on the flop and he bluffs+ keeps him honest when a diamond hits because I check called.

Agree? thoughts? I find myself doing this when I have nothing else but high top pair, no draw, on a 3 flush board
