When deciding whether to overcall an opponent’s 1NT opening, remember
• On hand shapes like 5-3-3-2’s, it may be better to pass and defend 1NT
• You need a bid to show single-suiters (6 + cards)
• You need a bid to show both-majors (5-5, occasionally 5-4 shape)
• You need a bid to show other two-suited hands (5-5, occasionally 5-4 shape)
• A penalty double over the opponent’s 1NT shows a hand in the upper range of the 1NT opening and is best made when you have a suit of your own and you’re on lead
• Aim for partscores rather than games when partner bids over their 1NT
• Suit length requirements may be relaxed in the balancing seat
• Two-suited hands are better declaring (one of your suits) than defending
Cappelletti is one of many conventions which may be used over the opponent’s 1NT opening - if not Cappelletti, choose another of them!
Here’s a video from an earlier lesson if you would like to do more revision on Overcalls over the Opponent’s 1NT.
