For the first of my post mortems, let me offer the following tale. You are playing in a local swiss against a team you feel you should beat. You are dealt the following hand:
♠K98764
♥853
♦KQJ7
♣---
You are at favourable vulnerability and there are two passes to you. You decide to make life as difficult as you can for opponents and bid 3♠. This goes Pass- Pass - 3NT! Eh? RHO passed in 2nd and can now find a 3NT bid? (I should note here that LHO passed completely in tempo). Well, what can you do? So you pass, LHO passes and partner (who obviously doesn't like the sound of this) doubles. So you lead the ♦K and are soon writing down -750 on your scorecard. Here is the full deal:
North said when dummy came down "I didn't like the sound of the auction, so I felt like I had to bid." I am of course thinking, neither partner or I liked the sound of the auction either.
We thought north's balancing 3NT should have been described as "partner I have a stopper if you have a long running suit."
Note also that 4♥ is down on a club lead, whereas 3NT is rock solid. Well, I think it's time for another pint after that.
P - P - 3♠ - P
P - 3NT! - All Pass
