pooltuna Posted August 24, 2009 Report Share Posted August 24, 2009 [hv=d=e&v=n&s=sk53hkdq5ckt86432]133|100|[/hv] East opens 4♥ WEST NORTH EAST SOUTH_____ _____ 4♥ __XP_____? Seeing some of the wimpy holdings that have been used to direct X preemptive bids how strong do you want South to be? Quote Link to comment Share on other sites More sharing options...
gnasher Posted August 24, 2009 Report Share Posted August 24, 2009 Just strong enough for me to make 5♣, as that's what I'm going to bid. Quote Link to comment Share on other sites More sharing options...

maggieb Posted August 25, 2009 Report Share Posted August 25, 2009 I would just bid 7♣. How would partner know to raise me to the cold grand slam with ♠Ax ♥Axx ♦Axxx ♣Axxx? Quote Link to comment Share on other sites More sharing options...

This is not a double of a 4H opening. You've been playing in the buffalo chips so long you are starting to throw them around everywhere if you don't think this is a X of a 4♥ bid. I have to ask, no matter how implausible it is, what call do you suggest South make? Quote Link to comment Share on other sites More sharing options...
Cascade Posted August 25, 2009 Report Share Posted August 25, 2009 South should be in the ball park of 15 HCP as a minimum with perhaps a bit less with some good distributional feature like a heart void or sharp cards. Quote Link to comment Share on other sites More sharing options...
gnasher Posted August 25, 2009 Report Share Posted August 25, 2009 This slightly dubious calculation may help to explain why it's unwise to bid more than 5♣: There are 22 missing HCP outside hearts, comprising three aces, one king, two queens and three jacks. Suppose that partner has 15 HCP, and has no honours in hearts. Partner's average number of aces will be 15/22 x 3 ~= 2. For slam to be good, you need at least an average of 2.5 aces. That requires his average HCP to be 2.5 x 22/3 ~= 18. Even taking into account that partner will place more weight on aces than on lower honours, it seems well against the odds to hope for three aces opposite.

Phil Posted August 25, 2009 Report Share Posted August 25, 2009 Easy 5♣. Not so much because we have the strength, but because we have the shape. You won't reach perfecto slams most of the time when your opponents open at the four level. That's life. Ron, the hand pooltuna posted is a routine double of 4♥.

aguahombre Posted August 25, 2009 Report Share Posted August 25, 2009 5C is not a weak-scared runout, it is a constructive advance after a double which does not particularly suggest takeout. But, I would feel like I should have bid 6 after choosing 5. Quote Link to comment Share on other sites More sharing options...
benlessard Posted August 25, 2009 Report Share Posted August 25, 2009 Over 4Hx you pass with all hands where you think you dont make anything and YOU DONT CARE if they can make 4Hx or not. Therefore a double of 4M preempt should show some hope of beating 4H facing very little. Like a better than average strong NT or better. Or a shapely hand with at least 3 defensive trick. 5C making 6 is what i would expect at most expert tables. IMO partner is favorite to have 3 aces here but he might easily have just 2 clubs. or you might have no wya to pitch the D. Give me the K of D instead of the K of H and ill surely bid 6.

That requires his average HCP to be 2.5 x 22/3 ~= 18. Even taking into account that partner will place more weight on aces than on lower honours, it seems well against the odds to hope for three aces opposite. This is worse than slightly dubious. Hands with a few honour cards and lots of spot cards are more likely than hands with lots of honour cards and few spot cards. Effectively this means that hands with a higher number of high cards are much more likely to be made up of aces and kings than queens and jacks. In fact it turns out that the average number of aces is very close to: ACES = 0.15 * HCP - 0.5 ACES(5 HCP) = 0.15 * 5 - 0.5 = 0.25 ACES(10 HCP) = 0.15 * 10 - 0.5 = 1 (Most people won't find this surprising) ACES(15 HCP) = 0.15 * 15 - 0.5 = 1.75 ACES (20 HCP) = 0.15 * 20 - 0.5 = 2.5 (People find this more surprising) etc This affect will be the same if we already know where some of the honour cards are. So that when there are relatively more aces missing they are much more likely to be with the hand with a greater number of high cards. That is I think your numbers are lower estimates for the number of aces given the assumptions about how many high cards partner has. I don't have a spreadsheet set up for the precise assumptions you made. But given our hand - 3 kings and a queen - and not discounting the heart honours I calculated that a 15 HCP hand opposite has an average of a little over 2.4 Aces and an 18 HCP hand opposite has an average of almost 3 Aces (2.98...). While unlikely there is also the possibility that partner has a heart void. Quote Link to comment Share on other sites More sharing options...
P_Marlowe Posted August 25, 2009 Report Share Posted August 25, 2009 5C. I dont care what partner has, I have a 5 club bid, nothingmore nothing less.Move the king of heart to anoher suit and I start thinking. With kind regardsMarlowe Quote Link to comment Share on other sites More sharing options...
WesleyC Posted August 26, 2009 Report Share Posted August 26, 2009 With no Aces and an ugly looking HK, 5C looks clear. Quote Link to comment Share on other sites More sharing options...
