Your partner opens with a pre-emptive three clubs and you try to find spade support by bidding a forcing three spades.
He bids three notrump showing something in the red suits, what now?
Scroll down when you have chosen your bid.
The blocked club suit doesn't bode well for playing three notrump and partner's lack of spade support may make four spades no play, so supporting clubs with a bid of four clubs (forcing) or a leap to five clubs is the best bet.
The full deal was as below. As can be seen five clubs is the best game contract, four spades needs a three-three spade break or the diamond finesse, or a fortunate heart position as below, which earns consolation marks.
