IMPs table. N-S are playing 2/1, 5542 and weak jumps.
The auction went in this not very common format. North fell in love with his hand upon 1♦ opening and decided to probe for 3NT, despite the chance of losing a 9-trick part-score was not slim.
Redouble was ruled out due to 9+ fit and improbable penalizing of a lower level contract.
Instead of 2♥, a jump to 2NT would show a maximum fit as well, but place a wrong dealer of an eventual 3NT.
However, South had a hard time deciphering pd's message. Were North's 2♥...3♥ bids unarguably forcing with a fit in diamonds, or they could convey some other meaning? You are welcome to offer your view.
