System Summary Form (SSF), 2021 Mixed USBC

Bids that Require Advance Preparation

2: Weak 2 in one of the majors (no strong options). May easily be 5-card suit, particularly non-vulnerable. May be very aggressive, particularly at favorable vulnerability. If 2nd hand passes, responder may pass on "anything". Does not show or deny anything. If 2nd hand doubles, pass by responder instructs opener to pass it out with 3+ diamonds if 4th seat passes. 2: Like Precision 2 opener -- 11-15, short diamonds, no 5-card major, no 6-card club suit. 2: Good 3 opener, just under or perhaps a minimal opening 1 bid. xx xx AQJxxx Kxx is a good prototype. 2NT: Both minors, less than an opening bid. Assumed at least 5-5, but may take liberties at favorable vulnerability.
