kjpod Posted September 17, 2017 Report Share Posted September 17, 2017 Curious hand came up the other night: [hv=pc=n&n=sj9hq5dq876ct8765&e=sq4hj9dkj42cqj942&d=w&v=b&b=4&a=4hpp4sppp]266|200|IMPs scoring[/hv] Partner leads the ♦5. Plan the defense if: a) Dummy plays the ♦6.b) Dummy plays the ♦Q. Quote Link to comment Share on other sites More sharing options...
The_Badger Posted September 17, 2017 Report Share Posted September 17, 2017 Partner can't have the ♥AK as he would led ♥s, so what has he got? 8 card ♥ suit due to vulnerability. ♦ lead is probably a singleton or doubleton at most. Why hasn't he led one of the other suits? Mmmm.... Both you and dummy are both 5-4-2-2 so what does that leave partner and declarer with? If partner has led a singleton or doubleton, he will be 8-2-(3 or 2-1). What's that leave declarer with? 8 or 7 card ♠ suit headed by an honour. 3 or 4 ♦s. The lead is important as partner can't have a higher ♦, so looks like declarer has at least good ♦ intermediates. I think I've seen this defensive scenario before in one of Kelsey's books. No entry to dummy, except on the opening lead, but declarer can't get back to hand to draw trumps and is locked in his hand thereafter, and that means he has to lose two ♦s if partner has led a singleton. So covering the lead won't help you one jot, whether it's a singleton or doubleton. So you have to duck with the East hand whatever ♦ declarer plays. That's taken me a good 15 minutes to work out. Phew! Quote Link to comment Share on other sites More sharing options...

Cyberyeti Posted September 17, 2017 Report Share Posted September 17, 2017 slow badger. timed out but youre right about ♦. lead 53 or 5 with 953 or T53 I lead 3 Depends on methods, many lead 5 from 953 but 53 or 5 is much more likely.

lamford Posted September 17, 2017 Report Share Posted September 17, 2017 I am going to play South for ♠AKTxxxx ♥K ♦AT93 ♣K and will duck whichever card declarer plays from dummy and now declarer cannot succeed. If declarer has ♠KTxxxxx ♥K ♦AT9 ♣AK this will let through the contract, but partner would have led a singleton club rather than a doubleton diamond.

Phew! Nicely done. Maybe this was too hard to work out in the time constraints of BBO. For the record, the S-W hands: [hv=pc=n&s=sak87652hkdat93ck&w=st3hat876432d5ca3]266|200|Not the ideal 4H opener maybe but far from the craziest thing ever.[/hv] Quote Link to comment Share on other sites More sharing options...
