Suit Establishment
In 3NT you have 8 top tricks in this bridge game. Where does that last trick come from to make the contract? The solution is to play clubs at every opportunity. The opposition have 5 clubs between them and as long as the suit breaks 3-2, if we keep playing clubs they'll run out before we do. Our last club becomes a winner.
What can go wrong?
It's important that we don't play our side suit winners too early. We need those to regain the lead each time we play a club.
