System Summary Form (SSF), 2025 Open USBC

Bids that Require Advance Preparation

General Approach is 2/1 with a short club and transfers. 2 is a bad 3m opening. Strength depends on vulnerabilty, but the suit is generally not good for 3N. Click here for approved ACBL defense Responses: - Pass - Indicates long spades but rarely a tactical call - 2N asks for suit/strength - 3 / 3 / 4 / 4 are pass/correct - 3M 1RF If 2 is doubled, system on except XX requests a bid of 2N where responder has their own suit 3m opening is very sound and invites 3N as a source of tricks. 2 shows specifically a minimum opening hand with exactly four hearts, a longer minor, and 0-2. It can also show exactly 1=4=4=4 and 15-16. Responses: - 2 = long spades, NF - 2N asks strength and minor. (3m = minimum, 3M max, 3N = 15-16 1444) - 3 p/c - 3 = inv+ in 's - 3 = blocking - 3 = natural GF - 4 = p/c - 4 = good raise to 4 2 is a weak two in a major. No strong option. Stated range is 3-10 (1-2-3) but is vulnerability-dependent. Six cards is expected vul, but five is acceptable NV. - pass = 4+ diamonds but occasionally tactical - 2 / 2 / 3 / 3 = p/c - 2N asks for suit and strength - 3 / 3 = asks about / length - 4 = 'transfer me' to your suit - 4 = bid your suit If 2 is doubled, pass shows diamonds, XX is bid 2, otherwise system on. 1 - 1 is a forcing NT with 0-4. Opener transfers over this. 1 - 1N shows 5. 1 / 1 / 1 are all 5+, deny a 5332, so will be 54 in two suits as a minimum. May open a good four card suit in 3rd or 4th if we do not have a rebid issue. 1 opening is 2+ (or exactly 4=4=4=1). 1 includes all balanced hands out of range for 1N, 2N or 2. It may include a longer side suit, and any 5332 shapes (even 5M332). responses: - 1 red = 4+ in / - 1 = no 4cM. May have any balanced strength. if minor oriented, should be less than invite. - 1N / 2 = / (inv+) - 2 = weak JS in major - 2 = 5 / 4, less than invite - 2 = 5+-4+ either way in minors - 2N = GF balanced - 3x = less than invite and long suit

General Bidding Style

Open nearly all 11's NV, but are more conservative vul. While a 1 opening is non-forcing, we rarely pass. Transfer responses after 1. - 1 is no major, may include many balanced ranges, INV+ minor two-suiters - 1N / 2 = Inv+ in / - 2 response shows a weak two in a major. - 2 = 5+ / 4+ (less than invite) - 2 = weak 5+-4+ minors (less than invite) - 2N = GF balanced - 3x = 6-7 cards, (less than invite) After a 1 opening and response, opener's rebids are transfers. 1N is either 14-16 or 15-17 depending on seat and colors. Many transfers in competition. Preempts and preempting strategy is down the middle.
