[Mbodell]

I've only got a bit of a pushy punt at the end with:

1♣ - 1NT (no 5 card suit, 2+ controls)
2♣ - 2♠ (4333 with a 4 card major)
2NT - 3♣ (3433 dist)
3♦ - 3♠ (3 controls - cold on A♠ and K♥ and with some decent play on all but A♠ K♣ so worth exploring and passing 3NT)
4♣ - 4♦ (none or both (top 2) in hearts - Therefore K of ♣)
4♥ - 4♠ (none or both (top 2) in spades - Therefore A of ♣)
6♦ (a bit of a gamble needing the A♠ onside and transportation or led or J♠, and the Q♦ or ♦ splitting 2-1)
