Very good  thank you  PK

I would bet  at least half the players with nmf  on they're cc do not  know  all this.....now if you or one of you  guys would like  to do same with the other popular conventions .....

The one I see most errors by  beginners  is jacoby transfers  

 Jacoby 2nt raises is also a popular one with lots of responses that some may not know

 

I am playing support x and xx   and now I wonder  if I know that well enough  does that have    complications too?
