1NT = (Good 14-17)

2♦ = Both Majors according the partnership agreement but was NOT alerted by West player.

3♣ = Natural

Do you take any action after partners failure to alert and 3♦ bid?If so whats your bid?

Edit due the questions in comments :P.S: It is a Pro playing with a flight C client and the client has forgotten the Cappaletti agreement, so there is NO way they have an advanced agreement on the meaning of 3♦ 

Getting results...
