IMPs, 13 board match vs reasonable standard opps.
EDIT: please ignore vulnerability in diagrams below. EW are vul, not NS.
1)
Do you open? You're playing ACOL (4cM, weak NT, three weak twos).
2)
Options are pass, X (PEN) or 2D (any 6+ suit).
3)
Opps are playing a weak NT, 4cM, with a runout system over 1NT-(X) where XX shows a 5-card suit and bidding suits direct, or via P forcing XX, shows two touching/non-touching suits. 2S was therefore described as unsystemic. X is penalty. Others are undiscussed but a new suit wouldn't be forcing.
Bonus points if you can guess how many IMPs were swung (total loss vs the gain we could have had).
