I was looking at the North hand after two passes. There are two schools of thought about opening with 4-5 minors; one says open diamonds to prepare a rebid, the other says open your longest suit, clubs, and see how it goes.
I absent-mindedly opened 1♣. This was a poor choice because I forgot about a third school of thought: open the suit you want led. It matters a lot here because I'm in third seat and the opponents are likely to have the majors and the balance of power. My stupid opening cost us dearly.
East overcalled 4♠ which ended the auction.
Partner had no reason to lead anything other than the ♣K. When her ♠Q also dropped I was marked with the remaining high cards, and declarer had no trouble ruffing out the hearts and claiming all the tricks.
