bergen raises

[sheilafran]

Do bergen raises still apply after a double???

 

 

after an intervening overcall ???

 

thanks for the help :

Usually not after a double, but you need something for the mixed raise, since 2N shows the limit. In partnership, we use a jump shift in the other major as the mixed raise.

 

(This is completely besides the idea of using transfers after doubles, which I like.

 

I've never seen anyone use Bergen raises after overcalls. A cue shows a limit raise +. Some play 2N as the mixed raise here.

[Double !]

Bergen raises certainly can apply after the opps make a "takeout" double. In fact, Bergen has suggested a specific structure of responses (acronym "BROMAD"- Bergen Raises Of Major After Double: "Better Bidding With Bergen, Volume Two, 1986/ pp 64-65).

 

Hope this is helpful

It all depends upon agreement. Usually, conventional meanings are off - or replaced by others - if opps double or overcall an opening bid. Ex being Jordan 2NT replacing Jacoby 2NT when opps double openers majorsuit.

 

I've seen people using Bergen after an overcall and double, and even using GF J2NT respons. However, the standard varies with geographical location. The sketch below is standard in my local club (personally I do not use Bergen), using the jump-shift to the suit below openers major as Bergen:

1H-(X/1S/2C)-3D being a jump raise - showing 7-9 hp, 4 hearts

1S-(X/2C/2D)-3H - as the jump-raise for spades.

1H-(1S)-2S* would be GF

1H-(1S)-2NT would be Jordan - 10-12 4 card support.
