Try this one from this week-end's cup final IMPs match. Expert pard and opps, of course
2♠ = muiderberg: weak two-suiter, spades-minor 5-4 or better.
As you can see, 6NT is cold. Our best effort was
2♠ 3♦ pass 3NT
(all pass)
I bid 3NT after like 3 minutes in the tank. Not very proud of it, but at table I couldn't figure out how to discover whether pard had the key cards, so I settled for a calm 3NT. Also, I reasoned pard, who is short in spades, might have had a considerably weaker hand for the overcall, say same hand without the club king, for instance.
At the other table it went
2♠ 2NT pass 4NT
pass 6NT
Easy bidding Despite this setback, my team still won in the end. We're now cup champions, yay!
