I pick this hand: Axx KQxxxx xx xx and the bidding goes, opponents silent: I Partner 1C 1H 2D 2H 2S 2NT 3H ? Now what? Partner is quite strong (reverse + 4th suit), if he has the right values, slam would be the right contract. If he has x Axx AKxx KQxxx, 6H is a piece of cake. If he has xx Ax AQxx KQJxx, 6H is makeable if they don’t lead S. If he has x Axx KQJx KQJxx, slam is out of the question, but 5H is reasonably safe. But if he has xx Ax KQJx KQJxx, even 5H is not makeable. If trump was a minor, TURBO would be nice. But with a major, we would go beyond game level, and I don’t want to risk that. What I would like is to TELL partner I have 2 keys for H (‘a la TURBO’), BELOW 4H, and let him decide to try the slam, or not. Is there a way to do that?
