2.
1♣ - 1♥
1♠ - 3♣
3♥ - 4♥

3♣, wow!!

If you think 3♣ is an overbid (I don't because you would bid 2♣ with a spade more and a club less), then by all means bid 2♣. Opener should still bid 2♥, and now responder has an easy 4♥ opposite 4-3-1-5.

How do you know it's a 5-card ♣ suit? Does everyone rebid 1NT if they're 4=3=2=4 or 4=3=3=3, even if the ♦ suit is weak?

Nobody should bid 3 suits voluntarily when he is 4324 or 4333. Besides, nobody bids 1♠ with a 18-19 balanced hand, and nobody shows extras with 2♥ having a weak NT.

He is referring to after the 1♠ bid...

Well, in this case he misread what Roland wrote...

"Ive said it once before but it bear repeating"


Its a must to know wich suit is longer if you like to get in with borderline 5/4 however there is better setup than Vertigo. My favorite for example is.


X= 5M and other suit maybe both M

2C= 5C+ other suit (maybe both m if you like)
2D= 5D +4M

The idea is that 5M+4m are less suceptible to preemption then 4M+5m. Also what you want is that

(1Nt)-----2D------(Z)--------3D is more frequent, if 2D show 5D instead of just 4D.
From Psych "I mean, Gus and I never see eye-to-eye on work stuff.
For instance, he doesn't like being used as a human shield when we're being shot at.
I happen to think it's a very noble way to meet one's maker, especially for a guy like him.
Bottom line is we never let that difference of opinion interfere with anything."

What perecentage of experts would you judge use the following conventions for defense against 1NT openers?
Cappelletti/Hamilton/Pottage
Multi Landy
Ripstra
DONT
Other...if so ,what is it?
As always, thanks for replies.
If I've overlooked another popular convention for this, please keep the sarcasm to a moderate level.

Multi-Landy, also called Reverse-Pottage, is one of many still popular conventions invented by Eric Crowhurst (Acol in Competition)

David Stevenson's web-site lists lots of other interesting defences, including Sharples.

How should East-West have bid their cold game in hearts?

With ease: West bids a Ripstra 2♣ and East bids 4♥.
... that would still not be conclusive proof, before someone wants to explain that to me as well as if I was a 5 year-old. - gwnn
