The upsides seem to be clarification of the 1D opener. Opener either has real diamonds in an unbalanced hand, or a 14-16 NT. This seems to take alot of ambiguity out of 1D. The obvious downsides are red vs white penalties...
Most of my experience so far has been at club level play and sectionals. Moving higher in tournament play am I going to have problems as a weak NTer?
Thanks for your replies
This is debateable, but I wouldn't play an 11-13 NT vulnerable. In 3rd seat I would even go as far as calling it suicidal; the reason being pard already confessed to have a weak hand (with prec you open on any excuse, so he's more or less broke and so are you LOL).
The ONLY time where I would MAYBE think of playing a weak NT vulnerable would be a 12-14 variant, with 1♦ showing an unbalanced hand 100% of the time. You could then try the following: dump the 2♣ opener into 1♦ and make it a sort of multi for the minors, with 11-15 hcp (the response scheme may include 2/3/4/5♣ responses as distributional pass/correct bids). That would allow you to use the 2♣ opener as a weak 2, a very underrated and very efficient preempt. Trust me on this
