Hand 21 at CBC, I have 5♠ headed by the KQ but decide to open this 1NT in the modern style.  The Ops now overcall 2♥ and partner bids 3♣ (the correct bid or not?).

Not quite sure what this means or how strong my partner is but given that my hand is good for 1NT, I decide to punt 3NT.  The auction ends here and play commences. I win the ♥ lead and play the 8♣ (only the K can beat it and it appears) - ♣ now set-up, I lose a ♠ to generate my 9th trick and contract now made!  I could have played up to my K♦ for one more trick early on but if wrong, I don't make the contract.  I had already decided that we were in a lucky contract and so decided to ensure I got it home!

I will open this hand 1♠ in future though as it is really too strong to open to 1NT.
