Five-level decision in a county match

[ahydra]

Sir,I beg your pardon,there are 6(Six) situations where Lebensohl is applicable.It s likely that perhaps you know only one.The remaining five situations is what I leave it to you to find out.The six situations were given in details by an International player to my daddy who passed it to me.If you wish to call it by any whatever other name it's your pleasure to do so.For me it is and will remain LEBENSOHL.

 

Are you PhilG007 in disguise or something? (see also your post on the other thread about 2NT rebids)

 

See here, or look it up in the Encyclopedia of Bridge, etc. The Lebensohl convention involves a 2NT bid over which partner is expected* to bid 3C. It may well have six usages - and I actually do know of four (the ones listed in that wiki article), but "after a 2-suited overcall" is not one of them! For a start, responder can't bid 2NT here - it's insufficient.

 

The convention of "after 2-suited overcall, one cue = 4th suit, other cue = good raise" is most definitely called UvU. Google it, look it up in a book, whatever you like; you will see I am right. (Though I guess you are still entitled to call it something else if you so desire.)

Is it standard to play that a limit raise+ sets up a forcing pass over the enemy game? Or does it depend upon whether:

 

(i) your side has actually bid game

(ii) the vulnerability

(iii) the level of the enemy action

 

?

 

I wouldn't expect a limit raise+ by itself to set up an FP, but if partner raises that to game I would then expect pass to be forcing. (Our criterion is "we've shown we've got game high card strength and opps bid above 3NT") There may be some argument for making things more stringent though - in some cases partner might be bidding on a weak hand with a ton of shape and opps' game could even be making, though in that case you would of course expect partner to bid rather than pass or sit a double.

 

We don't have a lot of experience with FP so expert input on VixTD's question could be useful here - e.g. I believe a number of expert pairs do only use FPs when at adverse vul.

Sir,one of your two guesses is correct.Which one? The second one where you say that I am fully entitled to call it by any other name and to me it includes Lebensohl.I feel sorry but your first guess is quite off the mark.I humbly request you to see my profile and you will see my real name.As regards my profession also you can get a hint from my interests.I ,thank you profusely for very kindly supplying the other details about encyclopaedia and all which by the way I knew already.In the end ,I wish to make a polite request " We agree to disagree".

The awful 5♠ bid is bidding the same values at least twice in the auction.

[Jinksy]

I have been thinking about the risk/reward for bidding 5♠

 

Compare results to other room playing 5♣ undoubled I will assign 40% to 1 and 2 and 20% to scenario 3

 

Result for bidding 5♠ 1 lose 150 2 win 550 3 win 0 (sometimes they will double)

So expected return from bidding 5♠ is 40% -150 40% +550 and 20% 0 = 160

 

So, maybe at teams, 5♠ is actually correct? You have to think that scenario 1 is 2-3 times more likely than scenario 2 to make not bidding 5♠ correct

 

On the NS hands and the EW bidding, we maybe want to be in 5♠. But it goes off regardless, and S has a far more suitable hand than he's shown - so if you're supposed to reach 5♠, I don't think it's North's job to get you there.
