  • Introduction to the 2 Over 1 Game Force System – Part 1 This Is the First of Two Articles Introducing the Basic Principles of the 2 Over 1 Game Force Bidding System
    Introduction To The 2 Over 1 Game Force System – Part 1 This is the first of two articles introducing the basic principles of the 2 Over 1 Game Force bidding system. In this article, I will discuss auctions when responder wishes to force to game. In the second article, I will discuss auctions when responder has less than game forcing values. In this article, I will also describe the “Fourth Suit Forcing” convention. Although not strictly part of the 2 Over 1 system, it shares some of the same principles. When I refer to “Standard American” in these articles, this is the same system as SAYC. SAYC stands for “Standard American Yellow Card”, so named because the ACBL has developed a yellow convention card which describes their recommended version of Standard American. In both articles, I assume no interference by the opponents. When the opponents interfere, 2 Over 1 and Standard American are identical. Basic Principles The 2 Over 1 system is actually very similar to the Standard American system. Auctions beginning with one of a minor or 1NT are identical. Many auctions beginning with one of a major are also identical. The only real difference between the two systems is when responder bids at the 2 level over an opening bid of 1H or 1S. In the 2 Over 1 Game Force system, this establishes a game forcing auction. The partnership may not pass until a game contract is reached. This is the main principle upon which the system is based. The only problem that occurs is when responder has an invitational but not game forcing hand (around 10 or 11 points).

  • BALANCING by Maritha Pottenger A
    BALANCING by Maritha Pottenger A balancing bid occurs when you are in the pass-out seat and an opponent has opened the bidding. Often, it is advisable to bid—hoping to buy or the contract or to push the opponents to a higher level where they might go set. If your LHO opens a suit, partner passes and RHO passes, most of the time your side will have 19-24 HCP and the opponents will have 16-21 points. (LHO could have as few as 11-12 HCP and RHO could have zero, but 13-17 is more likely for LHO and 2-5 for RHO.) You are bidding some of your partner’s values when you balance. The general guideline is that you will have a King less (3 fewer HCP) than you would need to make the same bid in the direct seat. The best times to balance are: 1) If you are short in the suit your opponent opened. (If you are short, partner may have length that made it harder for him/her to bid in the direct seat.) Assume partner does NOT have more than 15 HCP. If s/he did, partner would probably have overcalled one no trump. 2) You have a good 5-card or longer suit. 3) You have length and high cards in the 3 unbid suits. 4) You are not vulnerable. 5) You can bid at the same level (not have to go a level higher to make your bid). The worst times to balance are: 1) You have a very weak hand (usually less than 8 HCP) and/or a very weak suit.
