Yeah definitely lead. Weak- medium bet, hoping to get raised or at least called if he has air.

Minraise or 2.5x raise is not as bad as you think- villain on button will hastily call having had his ego damaged ("he was duped!") and might even suspect that you're making a play. He will slow down, or, if has a king and no brain, might raise it up. Who knows. check this one, and villain makes a flop bluff at it, but then gives up entirely. check-check-check-check-check-you show a river boat, table laughs at you.

In order to be deceptive, you must play your good hands and bad hands the same. Play them both strong. Don't try to trap every hand by letting others bet. If you set the pace and bluff enough (or get a rush of cards, both of which would generate action) you will get paid. Trapping usually sucks unless the blinds are high (when people bluff flops hard all goddam day), or you're got the deck locked up (flopped full house, few significant cards remain in play)
