(1) 16+, artificial
(2) weak
(3) 8-12, balanced, diamonds stopped
(4) Undiscussed territory
I meant the 3C as Stayman, but partner thought that (a) I had clubs and (b) I had extras, something like 21+ points. He wasn't sure what 4C or 4NT would have been, so he just bid what he thought we could make.
South led a low heart. North cashed his two aces and then, to add injury to insult, returned a heart for a ruff. 6C down 2 when the field was in 3NT making 5 was a cold bottom.
This hand illustrates once again (a) the importance of having firm understandings after interference over a strong club opening and (b) not torturing partner with undiscussed bidding sequences.
On the other hand, we got a cold top for bidding this heart game, thanks to a very informative Precision 2C opening and even more informative spade overcall:

(1) 5-4 in clubs+major or 6+ clubs, 10-15 points
(2) negative double (hearts)
With the spade overcall, I was able to visualize a double fit in hearts and clubs and a singleton diamond in partner's hand to go with the singleton spade in mine. I doubled and was happy to see partner raise to 4H with a maximum (14 points, in context) and good shape. Even though hearts broke 4-1, partner was able to lose a spade, a diamond and a heart to make the contract.
It turns out that North had a two-suiter in diamonds and spades and nearly all the missing points. Over 2C, they had no agreement on how to show this specific two-suiter and once it came back, the five-level was too high to show diamonds. Had they been playing Leaping Michaels, 4D would have been game forcing, showing diamonds and a major, but as far as I know, no pair in the Norman club game plays it ...
Partner and I ended the evening with 70% -- a long while since I've had one of those
