Funny board duplication in Tenerife #1


Recommended Posts

There were some 'duplication' in Tenerife, here is first example

 

[hv=d=s&n=sa109xxxha109daxxxc&s=skqxxxhkxxdxca10xx]133|200|Scoring: IMP

S - N

1-2NT

3-4

4-7[/hv]

 

Here the bidding shows why the Jacoby response should be used with at least 4 trumps: because you make the responder hand the base hand, reaching easilly 7 (althou I guess splinter might end up there also, but probably not as sure).

 

[hv=d=s&n=sa109xxxha109daxxxc&s=skqxxxhkxxdxca10xx]133|200|Scoring: IMP

S - N

1-2NT

3-4

4-7[/hv]

 

We had some missunderstanding on the bidding (* showed majors for one, and hearts for the other), but the contract wasn't that bad, after a K lead I ruffed in dummy, cashed A+K West discarding a , after that I played to assure only 1 off, but I missed a line that would had made as the cards lied, can you see the winning line I missed?.

Funnily enough, I remember another hand from Tenerife also in the same idiom:

 

[hv=n=sa10xhaxxxdcakqxxx&s=skqxxxhkxdaxxxxcx]133|200|Scoring: MP[/hv]

 

They bid to grand against us.

Ooooops sorry, On the 6 contract West made the mistake of discarding a , not a . That meant that the standard line of trying to find West with a singleton honnor should be dismissed. Any other chance?

Ok, here the full hand if anyone ever though about solving the problem:

 

[hv=n=saxxha109xdcaxxxxx&w=sq9xhxxdkqjxxxxcx&e=sj10xhqjxxdxxxcqjx&s=skxxxhkxxda10xckxx]399|300|[/hv]

 

After a ruff A+K I couldn't imagine s 7-3 after the 1 overcall, but if I did, finding the endplay for 12 tricks should had been possible.

That's an upside-down reasoning, gonzalo. If North were opener, South would have bid 2NT as well and you'd hardly get to 7S now.
