2/1 method in response to Aug ACBL Bulletin


There was an article in August 2014 ACBL Bulletin on fixing 2/1. It gave a patchwork of suggestions with the reader left to pick and choose, this article is my choices and some additions for 2/1 in 1st and 2nd seat only. The methods are slightly different for 1♥ so will show responses to 1♥ first. I haven’t given continuations in most cases but it’s not hard to come up with continuations.

 

1♥ Responses:

1♠ -      4+♠ 5+ hcp F1

1N -     5-12 hcp F1 may contain upto JT9 ♥ support

Will take a false preference with 2♥ and 3 of minor and live with occasionally ending up in poor fit.

2♣/2♦   4+m 13+ pts GF Also, may include solid or semi-solid 7+ card suit which has tricks but not 13 hcp.

2♥        (5)6-10 pts 3+ card support if 5-7 pts, 3 card support with 8-10 pts NF

2♠ -      4+♥ 8-10 pts constructive  raise (Bergen) or your normal 3N bid which for me is 33(43) 15-17 hcp with at least a partial stopper in unbid suits. If opener signoffs responder can bid 3N with the 15-17 hcp hand.

2N -     Qxx or 4+ card support or better (10)11-12 pts INV or 4+ card support 12+ pts GF

3♣ -     6+♣ 10-12 hcp INV has 0-2 cards in opener’s major

3♦ -      6+♦ 10-12 hcp INV has 0-2 cards in opener’s major

3♥ -      preemptive raise, 4+ card support NF

3♠ -      4+♥ 0-1♣ 13+ pts transfer splinter GF

3N -     4+♥ 0-1♦ 13+ pts transfer splinter GF

4♣ -     4+M 0-1♠ 13+ pts transfer splinter GF

Using transfer splinters means there is always a bid available as a slam try below game.

4♦ (over 1♥) -  Swiss Raise, 4♥ balanced (but not 3-4-3-3)13-15 hcp and 3 keycards GF

This an extra bid that compensates for loss of 3N. Another possible use could be a preemptive raise with some defense. Other uses are possible.

4♥ -      usually a preemptive raise, but may be bid to make with no slam aspirations

 

1♠ Responses:

1N -     5-12 hcp F1 may contain upto JT9 ♠ support
