Flannery

Today I want to advertise a very nice convention, which brought us a lot of fun and good results.
I'm wondering why this convention is so underrated.

Here we are I introduce to you Flannery.
Ok you have not the weak two in diamonds. That is the price we pay and we pay it happily. We had in 10 years not one bad board for the reason we couldn'T open a weak 2 diamond.

Here is an example how flannery works:

Out of 16 pairs in BBO only one other pair found this game in a 4-4-fit with 20 HCP
Admitted I was lucky in finding partner not with wasted values in hearts.
