Interesting bidding.
Let's look at North's bidding - I can only think they had a club stuck in their spades!
Let's look at East's bidding over 3S. How much does East know about West's hand? Not very much, only they did NOT want to play in game (which incidentally is where u have now bid). How much does West know about East' hand. Well, quite a lot. This suggests that West should determine the fate of the hand not East. After a weak 2 or any pre-empt partner is now the Captain of the ship - obey his orders but otherwise be silent.
What is the correct bid with the West hand? Pass or raise. I have a lot of sympathy for West's bid. Oppo are likely to have game somewhere and u are just trying to screw the scrum, right?
Well, I did just this a couple on times and my partner commented that this wasn't expert practice. That's fine, but why, what's wrong with a 6-2 fit? At this point it becomes an experience thing built up over thousands of hands. I decided to put it to the test - but how?
DDA doesn't work for "screw the scrum" situations, as DDA works on "perfect vision" thus u can't screw the scrum. Enter SDA - single dummy analysis. This is quite tricky and no "off the shelf" software apps exist. Essentially what I finally managed to achieve was to generate a number of hands suitable for the task (easy). Then give it to robots to bid and play in all four positions (also relatively easy). Then to get them to do this on hand after hand automatically (really really hard), so u build up a sufficient sample of what works, what doesn't. To be honest, took me absolutely ages. However I got there. Took a bet on the outcome and ran the analysis. LOST comprehensively, wasn't even close.
So, next time at the table in real life, faced with a "similar" situation I passed with negative consequences. Latter pard said, "HOWEVER in this slightly different situation ...." It takes many goes to get a good block of cheese!
