So this can come up over a standard player who opens the "could be short" 1♣, but happens to precision folks who open the "could be short" 1♦ not that infrequently. The opponents bid 2nt, unusual 2nt over 1♦, but then aren't sure if they are showing ♣+♦ because your 1♦ might be "fake" or ♣+♥ because your 1♦ might be real.

We normally play the straightforward U/U where their lower shows our lower and vice versa. When they aren't sure what they have (like here where they have clubs and a red suit), what sort of U/U or conventional treatments do people play?

Hi,

keep it simple, assume in this scenario, they play your version of Unusal.

If we play against precision / polish club, we have a short sync up, how to treat
their 1D opening.

With kind regards
Marlowe

P_Marlowe has it. We must agree what our bids mean even if they don't know their bids meaning. Why slip into manure on a stinky auction?
