double is card showing and take out oriented.
I usually bid 4NT with 6-5 two suiters.

发帖数: 623 | 3 If you need 6-5 for 4NT, how do you show them in an equal conversion
situation? If you have no way to show, then there's no point; if playing
strength's the thing, then this hand should be good enough.
The downside of double is that pd may choose 5D with 2-2-5-4, eg, xx Kx AKxxx
xxxx.
The upside of double is that this hand has some defensive value and in some
layout, pd can convert for profit.
Since one can convert x, it seems more reasonable to play x as take out mainly
for strength, and 4N as

发帖数: 3277 | 4 the point is that
with 5-5 two suiters you can seldom commit to 5 level.
Because for 5-5 two suiters, the offensive value usually isn't enough,
unless it's very pure:
I'd bid 4NT with this hand: Sx HAKQxx DKQJxx CKx, because it's pure.
for 6-5 two suiters, it's usually pure:)
sometimes, I belive you can bid 4NT with 5-4 two suiters when white:
Sx HKQJTx DAKJx Cxxx, this hand looks very pure, I don't mind
to five level with such a hand when white.
The basic idea is the ODR, if ODR is very high, | w****b
发帖数: 623 | 5 I think we are very much on the same page on this one, only that I think 5-5
is shapely enough and you doubt it. :-)
Also note on this hand that you are on balancing seat. The x on balancing seat
would have greater chance to be converted (than direct), in which case a
slightly lower ratio would qualify for 4NT.
