People just can't help but bidding the same thing twice, and even more times.
Does this hand have noticeably more defensive value than a normal opening hand?
Bidding is not just showing your hand. It is also taking decisions when pard has shown enough of his hand. I think this is one such case: you sure don't want to bid 5
♥ and you know the hand is yours. You must take charge and double. Passing would be encouraging for pard to bid 5
♥.
I think you meant '6
♦', not 5
♥.
However, pass does not, logically, invite partner to bid 6
♦. This is not a forcing pass situation, and I know of no partnership that defines forcing passes in such a manner as to make this one such a pass.
Neither N nor S has suggested that they had a big hand, and were bidding 5
♦ confident of a plus. North expressly rejected holding a big hand by the negative free bid approach: presumably S was permitted to pass 3
♦ had it come back to him... thus 3
♦ did not establish any force whatsoever.... and it is illogical to allow the opps' bid over 3
♦ to change the implied degree (lack) of force created by the call.
5
♦ did not announce ownership of the hand: it may well have been a save or an attempt to push the opps to the 5-level, expecting to have a better chance of beating an 11 trick contract than a 10 trick one.
So the pass/double decision should not be impacted by any worry that a pass would fetch a 6
♦ call from partner... any partner who bids 6
♦ should be taken out and summarily executed...... unless it makes, of course
Ok, so do we defend undoubled? It is matchpoints and it may be that we have already put ourselves into a no-lose position PROVIDED we don't do anything disastrous.
Consider the auction at other tables: few pairs play NFB, so unless partner has a super-maximum, we may not have found our
♦ fit.
Perhaps partner could have negative doubled, and perhaps we would have bid 4N over 4
♥ and thus found our way to 5
♦, but, in a typical matchpoint field (we are not, I asume, speaking of the finals of the Blue Ribbon Pairs etc) it must be realistic to assume that a good chunk of the field will be defending 4
♥ undoubled.
So if we beat 5
♥, no matter whether it is by one trick or two, we rate to score about 65% if we do not double and, say, 90% if we do.
But if 5
♥ makes, undoubled, we rate to score about 50% or so (losing to those who are allowed to save in 5
♦ but winning against those who double 4 or 5
♥) while if we double, we rate to score about 5%.
This suggests that we should double only when we feel that we are at least 2-1 favourites to beat this contract... I think that we are definitely likely to beat this contract.. the question is do we jeopardize a reasonable score looking for a great score?
This decision is so close that I would be influenced by how late in the game this was, how big the field was, etc. If early in the game, or late with us needing some good boards, or if it were a big field (a regional pairs game, for example, where big scores are needed to win) I would double.
If this were late in a club or sectional pairs game, where we were doing okay, I'd pass and take my expected 65% rather than risk a disaster.
