Looking at your Hole-cards

You shouldn't have to Look at your cards more than once. When it's your turn to act, look at your two holes cards, and remember what they are. Cap 'em, and leave 'em there for the rest of the hand; unless of course, you wish to give your opponent additional tells. The most common occurrence I see is when two of the same suit comes down on the flop, and someone wants to know if they have a third card of that suit. Because of course, they expect to suckout a flush on the river, which only happens, what, less than 1% of the time? In a game of limited information, I simply don't understand why other players are willing to give more information to me.
