 | When opening a one-bid in a minor suit: with three-three in the minors, always bid one club; with either four-four in the minors or four diamonds, five clubs and a minimum-range hand, use judgment to decide which minor to open. |
 | After a one-club opening, responder normally bids one diamond with longer diamonds than either major, or with four-four in diamonds and a major in a hand worth at least a game invitation; but the normal response is in a four-card major with a minimum-range response and four-four in a major and diamonds. |
 | A single jump-overcall of a suit opening in direct position is preemptive, in reopening position has a strength range roughly equal to the value of one king and shows at least an opening bid with at least a strong six-card suit (by a passed hand, shows a similar hand limited by context). |
