If partner opens one of a major, say one heart, I was taught that a responder could raise to two hearts with three of the suit and six high card points, or bid a new suit "one over one" (e.g. one spade) with six high card points and four of the suit.
But I often like to raise to two with as little as "four and four" (that is, to two hearts with only four high card points but four hearts instead of three. This is particularly true if I have the queen of hearts, because a queen that's a "filler" in partner's suit is worth more than two points.
I also like to bid "one over one" with "five and five" (only five high card points and a five card suit), say, one spade with KQxxx, or AJxxx and no side honors.
Finally, I like to pass with a "weak" six or even seven. That might be something like (s) Qxx (h)xxx (d) Qxx (c) QJx, that is all "quacks," no aces or kings, and no honors in the opened heart suit. Or (s)xxxx (h)Jx (d) QJx (c) QJx, again all "quacks," no honors in the four card suit, and no real support for hearts.
(All xs are 8 or lower.)
Are any or all of the above reasonable postures? Or should I stick more closely to the six point rule because of what partner might or might not have?
