If 2♦ shows that the 1♠ opening is worse than specified by their system, then 2♣ is a psych (or deviation) control... similar to Drury :). Such calls are illegal in some jurisdictions.

jeffford76 Posted May 13, 2013 Report Share Posted May 13, 2013 Whether the 2♣ bid is legal depends on what conventions are allowed where you play. It's not legal anywhere to describe it as a "game force" if it's not. 1 Quote Link to comment Share on other sites More sharing options...
mink Posted May 13, 2013 Report Share Posted May 13, 2013 It looks like that the correct explanation for the 2♣ bid would have been: "any gameforce, except partner's strength is less than xxx". If this is what they really play, it was legal if explained correctly. Karl Quote Link to comment Share on other sites More sharing options...
RMB1 Posted May 13, 2013 Report Share Posted May 13, 2013 It look primarily to be a disclosure issue: 1♠ = 5+, our agreement may be 11-16, but we understand it could be weaker2♣ = forcing, artificial, forcing to game except opposite a "sub minimum" opening2♦ = subminimum, 0-10 I guess2♠ = non forcing, to play In various places 1♠ may not be permitted unless it is 8+HCP, and artificial non-GF responses such as 2♣ are not always permitted.

ggwhiz Posted May 13, 2013 Report Share Posted May 13, 2013 As soon as the 2♠ bid is alerted or explained as to play either defender has a case for bidding if 2♣ had been properly explained as any invitational plus. Come close enough to making that case and I'm adjusting in your favor. Unless 1♠ was a flat out psyche and 2♠ WAS a legit continuation (slam try or probing for 3nt) we need to have a little chat with this pair. If this was the case, we still need to have a little chat with this pair. Quote Link to comment Share on other sites More sharing options...
