This was the strongest hand I think I've ever seen.
I opened 2♣ and rebid 2♦ showing 23+ points. Partners 3♦ is a transfer to hearts. Interestingly, if you super accept - you will never work out that your partner had 6 hearts! By quietly bidding 3♥, partner was able to show the 6th heart by bidding 4♥.
I could now count 13 tricks, I have 7 top tricks outside of hearts, and can expect 6 heart tricks opposite 6 bad hearts, if they break if they don't break 3-0.
Over 4♥, I just bid 7NT - slightly safer than 7♥ in case there is a ruff on the opening lead.
