Similar flop to VinceVegas' hand

[Kayber2]

$100/200 at the Muckleshoot casino 6 handed. I raise T9 of clubs UTG (please no preflop critique. I know the T high 9 kicker is not in the preflop starting hand chart from this position). 2 cold calls behind me and the small and big blind call. 5 ways to the flop.

KT5 with 2 diamonds, it's checked to me and I check to see how everybody feels about their hand. Basically the 2 blinds would almost always try a checkraise here with a K or better and the guys behind me would definitely bet a K, set but maybe not a draw or a T. The flop is checked around.

Turn makes the board KT58 and now there's a heart flush draw as well as a diamond draw. The small blind checks and the big blind bets. The big blind is not folding pairs heads up today (he'd never fold 77 if it was heads up on this board) wouldn't 3bet a draw here but would definitely bet one.

I decide to raise and check behind all rivers that don't give me 2 pair. Good idea?
