Everybody knows cbetting, semibluffing.

My favourite is in BB. Pot-raise the table full of limpers then pot it on flop against single caller. Then show down 72 offsuit and enjoy the next ride while having AA/KK...

Or:
Check-raise re-bluff on scary flop. Flop is for example drawless JJ3, table full of limpers, checks around, button donkbets it (pussy 1/4 pot bet), then I slam a raise 3x his bet or 3/4-full pot and get folds around.

Fnord made recently an interesting topic about "any two cards on any flop" move...
