My left hand opponent opened one diamond. Partner doubled. Right hand opponent passed. I was sitting in fourth seat with eight points, and something like
(s) KJxxx (h) Jxx (d) xx (c) Kxx.
I "jumped" to TWO spades (instead of bidding the minimum one spade). With Qxx in spades and 13 points, partner took us to four, which went down two.
Partner said, "I thought your jump meant you had an opening hand. That, opposite my 13 means game." My opponents were also confused by the sequence.
My reply was that since I was forced to bid one spade with "nothing," a jump to two spades (which was the right level), meant that I was making a "non-forced" bid with a real (intermediate) hand of 7-10 points. Given that he had a minimum takeout double (and a minimum spade holding), I expected partner to pass.
Opposite a takeout double, does a jump bid of "one more than necessary" in a suit indicate moderate values? Or was partner right to expect an opening hand?
