Playing a big club system, your partner has shown 11-15hcp, exactly 4 spades, and 5+ clubs. Pard can't be 4405 or 4315 on the auction you've had. The opponents are silent.
So, playing teams, and knowing what you know of your partner's hand, do you have game forcing or merely invitational values? Where do you want to play this hand?
