How much do you expect?

[mike777]

Well, the one auction they are missing is the:

 

1C-1S

2D     auction.

 

I would tend to play 2H is the weakest action since the 4th suit is very much an unlikely place to play.  When you don't have room, then 2N becomes the sign off.  2S could clearly be the right spot and you can get there.  Parter may have Hx and have a nice 5-2 fit you could get on the two level.

NO!

1)2h=game force..

2) 2s=5+spades...weak bid.

3)2nt=deny 5spades......but otherwise weak bid.....do not promise balanced hand..do not promise stoppers.

4) any 3 level bid=natural and game force.

5)Yes,not perfect but handles many many common hands.

East holding ♣Jxxx and ♦Q can envision declarer testing clubs before falling back on the diamond finesse, and thus leads a diamond to put North to a guess.

And North takes the finesse at trick one. Wasn't this covered by Jon's analysis, several days ago?
