Doing the bidding practice from L.Cohen site with my partner

IMPs

---

If East bids 3♠ iso DBL then we have agreement that it is GF.
West can open 2♦ and rebid 3♣ to show GF in ♣.
Or West can open 2NT 20-21, but thought his hand was too good for it and not balanced enough. 2♦ followed by 2NT would have been 22-23.
East thought that he didn't have enough for 3♠ GF, and that he had bid enough with the DBL.

So, how should we bid to 7...or 6?

I think west should just force to slam, but I would never get to 7 after the 3♦ bid. East did well to double instead of pass although after 1♣ 3♦ P P X P 4♠ west could bid again anyway I think.

Not sure the double was helpful it's difficult to work out that there's a 5th spade there. I think it's easier over 1♣-(3♦)-P-(P)-X-P-4♠ (4N-5♦-5♥-5N-6♣-7♠-7N).

If he has just four spades he will be stronger than he was.

Agreed, he might have the nice helpful red queens, the point being AQxxx/Qxx is actually more use to you than AQxx/Qxxx/QJ/Qxx and you will struggle to tell them apart.

I think I had opened a 22/23 NT. I have no idea what this West had done over a pass from LHO and a simple 1 ♥ from partner....

The bidding at the table makes it not easier too. Anyway, over the double, West should force to a slam. All of partners points are working, so slam must be good. But I see no convincing way to go to 7. You need to find out about all honours in the East hand and the 5. spade- impossible for me.

Of course a direct 3 ♠ bid instead of the double had helped- but Easts hand is far away from a GF 3 Spade bid.

on the website they proposed to open 2C:
2C-(3D)- 3S
4NT-...

How should West force to 6? Via 4NT (RKC) or 5NT (pick slam) or...?

This is why you miss 7 as lalldonn said.

Which is why I said pass then 4♠ was more helpful than the initial double, as now you can bid 7.

What should West bid iso 5♣?
5NT pick a slam?
