6♣. My plan is to set up hearts with a ruff (West can't ruff high), and finess East for his club-values. That should make 13 tricks. I am, however, always unlucky, so I underbid with 1 trick. I am going to have to guess on this hand anyway, so i might as well give the opponents a guess too, instead of making a feeble attempt to introduce hearts, which East might easily control, since he bid 2NT.
