Thursday Morning Riddle

I’m the third piece in suits you remove when you’re hot;
To endow with a power, like tying the knot;
Keep your cards close to me, or they’ll see what you’ve got;
I’m flotation at sea; or protection when shot.

Who am I?

UPDATE: Riddle solved by Jason. See comments for answer.
