Following bidding sequence: W___N____E____S -___1♥___1♠___3♦ Playing BWS2001defaults: 3♦, a jump shift, is pre-emptive. What would be 4♦ ? Staying in the same line of thinking, one could propose 4♦ as equally pre-emptive. But almost equally defendable: as the double shift is not explicetedly defined, only the single jump is, 4♦ should be, according to the BWS defaults settings, natural: a strong single suiter. Any opinions ? Besides: do you really think - taking into account the other BWS-agreements after an overcall of our 1♥ or 1♠ opening - that playing that jump shift as pre-emptive is the best use of that bid ? This is one of the sequences where I have difficulties following the BWS standard. I would prefer to play 4♦ as a good ♠ raise with a ♦suit. Im not so sure about 3♦. All opinions welcome. Any ideas about the use of jump shift responses, after an intervention of our 1 of a minor ?
