• Overcalls will always contain suits of at least five cards, whether a major or a minor e.g. ♠ AKJ107
• One-level overcalls should be made aggressively on 8+ points e.g. Overcall 1♠ after a 1♣ opening with as little as ♠ AKJ107 ♥ 1086 ♦ 9 ♣ 8765
• Two-level overcalls require a better hand (opening points) e.g. Overcall 2♦ over a 1♥ or 1♠ opening with a hand as good as this: ♠ KQ8 ♥ 1086 ♦ AKJ1074 ♣ 8
Overcalling 1NT shows a hand that would have opened 1NT (15 - 17/18) and a “stopper” in the suit opened.
• Responding is based on the fit rather than points (the bigger the fit, the more you should bid)
• Jump raising partner in competitive auctions shows a weak hand, but with four or more cards in partner’s overcalled suit
• To show a good hand with a fit, use the cue raise e.g. 1♣ (overcall by partner of 1♥) P 2♣ = good raise for partner at least three trumps and 10+ high card points
• Change of suit over an overcall doesn’t have to be forcing but shows a suit of a quality similar to the overcall. (Discuss with your partner which you’d prefer to play; forcing or non forcing)
• More points are needed to overcall when your side is vulnerable than when not vulnerable
