West is a little light for a two-level overcall but has extra distribution. There is a convention to show both minors - the unusual 2NT. However here east-west are vulnerable against not vulnerable opponents. So it is dangerous to force to the three-level.
3NT shows norths diamond stopper and values even if the diamond stopper is a bit weak. However with four hearts it will usually be better to explore for a possible 4=4 (or occasionally better) heart fit. The way to do this is to make a negative double of 2D.
This time 11 opposite 13 is not enough for game though. That happens.
Negative doubles is a conventional use of double to ask partner to bid. Conventional just means the double is not for penalties.
Usually the emphasis is on the unbid majors. Here are some auctions:
1C (1S) X - the double shows four (or more hearts). If more than four hearts then not enough strength to bid at the two-level, so less than 10 hcp.
1H (2C) X - the double shows four spades and about 8+ points. Again with 5 spades and 10+ points you can bid 2S. Therefore with less than 10 points you might double with 4+ spades. With only four spades you can have any strength.
1C (2S) X - the double shows four hearts and about 10+ points. The ranges aren't precise but the higher you are when you double the more points you will need.
There is one special situation at the one-level and that is when the opponent's overcall 1H. Now double shows four spades and bidding 1S shows 5+ spades.
1C (1H) 1S - five or more spades
1C (1H) X - precisely four spades
There are additional subtleties but this should suffice to give you a start to understanding negative doubles. There are also some variations so some partnerships might play a different style of negative doubles.
Also the emphasis on the majors is quite strict when the double is made at a low level but at a higher level you will more often have to be more flexible. So
1C (1S) X pretty much guarantees four hearts
whereas
1C (3S) X you might have to make on any hand with a bunch of points - about enough for game - that didn't have another clear bid.

Its hard to see how 3NT actually made at the table.
ReplyDeleteHi Wayne review of these hands is really helpful. In this hand can you explain a negative double
