broze Posted November 20, 2015 Report Share Posted November 20, 2015 This would be definitely be quant for me since 4m then 4N must be RKCB for spades. Quote Link to comment Share on other sites More sharing options...

I wasn't sure whether the standard meaning of 4♦ should be "diamonds" or "I like spades". Quote Link to comment Share on other sites More sharing options...
kuhchung Posted November 20, 2015 Report Share Posted November 20, 2015 4D should be a big raise to 4S. Agree that 4C is natural, and it looks to me like 4N is quant. 1 Quote Link to comment Share on other sites More sharing options...

Yes it probably is. I'm not really familiar with this art 3c treatment Quote Link to comment Share on other sites More sharing options...
mgoetze Posted November 20, 2015 Author Report Share Posted November 20, 2015 Yes it probably is. I'm not really familiar with this art 3c treatmentEh it's just standard 2/1. Clubs or single-suited too strong for 3♠. Quote Link to comment Share on other sites More sharing options...
broze Posted November 20, 2015 Report Share Posted November 20, 2015 Eh it's just standard 2/1. Clubs or single-suited too strong for 3♠. I know what the convention is but not the followups. Now you have shown the spade single-suiter you don't have clubs most of the time anyway so you could argue why treat responder's minors differently. Okay opener is sometimes 6-4♠♣ - I suppose you may as well use 4C to catch this... Quote Link to comment Share on other sites More sharing options...
PhantomSac Posted November 21, 2015 Report Share Posted November 21, 2015 4D should be a big raise to 4S. Agree that 4C is natural, and it looks to me like 4N is quant. 100 % this. If your options are 3N and 4N, and you have a way to raise the last bid suit (here 4D clearly is that), then 4N is quantitative. Quote Link to comment Share on other sites More sharing options...

I wasn't sure whether the standard meaning of 4♦ should be "diamonds" or "I like spades".4th suit at the 4 level is typically best used as a good raise. If Responder had wanted to introduce diamonds they could have done it the last time around. It is not like a quantitative 4NT rules out finding a diamond fit either assuming natural continuations rather than any sort of ace-showing (ie 5♦ now is usually going to be a max 6034).
