TURBO for Major?

[CyberCard]

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?

Some use 3s/3N as turbo calls.

 

Good 1345 should be splintering over 2h.
