Ignoring the merits or lack thereof of my 1nt call:
- 1nt is described as "2-5 C; 2-5 D; 2-", description seems cut off
- opener's double of 1nt is described as 16-21 HCP so why is it doubling on 13?
- why is opener doubling 2d showing "2+D" with 1 diamond?
Somewhat related to this is auctions like 1S-p-1nt-2d;dbl. I think GIB plays these doubles as penalty but modern std I believe is takeout. Doubles showing 2+ of a suit are weird. Either it should be 4+ and penalty, or 2- and takeout. 2+ and penalty is just weird.
