PhilKing Posted January 28, 2013 Report Share Posted January 28, 2013 I can cater for hearts 5-0 if diamonds are 3-2, but I won't give away my line just yet ... Quote Link to comment Share on other sites More sharing options...
Zelandakh Posted January 28, 2013 Report Share Posted January 28, 2013 I can cater for hearts 5-0 if diamonds are 3-2, but I won't give away my line just yet ...Do you test the diamonds before making the commitment. The line I had in mind merely handles 4-1 for both or 5-0 diamonds and 3-2 hearts. Maybe your line goes beyond N/B Phil. Quote Link to comment Share on other sites More sharing options...

TWO4BRIDGE Posted January 28, 2013 Report Share Posted January 28, 2013 (edited) I can cater for hearts 5-0 if diamonds are 3-2, but I won't give away my line just yet ...I can see how to test for 5-0 in ♦ , but not for a 5-0 in ♥ . If after you immediately ruff a ♠ and lead a ♦ - - and all follow - - would you commit to the 5-0 ♥ / needing 3-2 ♦ ( 71+% ) or go for the 4-1 route in both reds ( 96+% ) ??EDIT : I think the answer is obvious, and the ♠ - ruff ( post # 4 ) is wasted effort .

I'm glad the answer is obvious. Trick two, spade ruff. Trick three diamond. If they are 5-0, I will need 3-2 hearts. When everyone follows, draw trumps overtaking the second round. If diamonds are 4-1, revert to the "n & b" line :P. If diamonds are 3-2, claim. When hearts are 0-5 my tricks are five diamonds, two spades, two clubs and 4 hearts, but I needed some wasted effort at trick 2 to get to thirteen.

I see it now ( finally )... you don't commit to the possible 5-0 split UNLESS trumps are 3-2 ... BUT the early ♠ ruff is needed for the 13th . And if ♦ are 4-1, you play for the 4-1 ♥ split. Soooo, it looks like your ( combined ) line is nearly 100% . Quote Link to comment Share on other sites More sharing options...
Zelandakh Posted January 29, 2013 Report Share Posted January 29, 2013 I'm glad the answer is obvious.Not to me sadly. I wanted to ruff a second spade after a trump but this is clearly inferior. Failing on N/B problems is pretty bad for the ego! Quote Link to comment Share on other sites More sharing options...

xx1943 Posted February 2, 2013 Author Report Share Posted February 2, 2013 http://www.albrecht-hollstein.de/Bilder/Almispalyed7Dia-prob.jpg Phil told us how to win this grand with 97,6% 1) Ruff a spade in trick 2 is a precaution against hearts 5-02) A round of diamonds revails the situation. a) If diamonds are 5==0, hearts must be 3=2, because you have no trumps to ruff even 1 heart. Cash the other high trump in dummy. Go back to your hand with the Q, pull all trumps and test the heartsThe spade ruff was not necessary, but didn't hurt. b) If diamonds are not 5==0, overtake the last diamond in your hand and pull 1 or 2 more rounds of diamonds (just to exhaust opps of trumps). You have 2 or 1 trumps left to cater vor hearts 4==1 or 5==0. Quote Link to comment Share on other sites More sharing options...

It is an easy problem in theory imho.The difficulty is to think of this bad distribution at the table.I'm very ashamed because I misplayed the hand, when it came up.Here is the link to the original hand. This problem is very useful for beginners in 2 ways1) To recognize such a situation. You must have seen such things to be aware of.2) To learn the necessity to care for very bad distributions, if you are in a good contract. It happens so often, that you forget the precautions, if you are euphoric about the nicely bidden contract. Regards Al Quote Link to comment Share on other sites More sharing options...

I just said it in jest because of this thread: http://www.bridgebase.com/forums/topic/58285-how-to-deal-with-new-forum-posters/page__st__20 Your point number two is applicable to all levels of player. But as far as I am concerned, it makes no difference whether you put it in "Interesting Bridge Hands" or "N & B". Back to the hand, clicking on GIB, I notice that playing the ♦A or K at trick two is also OK. Quote Link to comment Share on other sites More sharing options...
