Double Dummy unsolved

Recommended Posts

I played a hand with WBridge5 program. After i made 6 one down , computer calculate that the par is 6NT=

The hand is :

[hv=pc=n&s=sak9h93dakt764c63&w=sj7543hq62dcjt982&n=sqt6haj4dq852caq7&e=s82hkt875dj93ck54]399|300[/hv]

The lead is 8. I tryed different squizes , but -1 anyway.

I miss something?

The 7 is the key card.

 

Just run the spades and diamonds. On the fifth diamond, West has to keep three clubs, otherwise we can establish the suit, so both West and dummy throw a heart. On the sixth diamond, West also has to throw a heart. Now we can pitch a club from dummy and end play East with two rounds of hearts.

 

It looks like a heart or club lead would beat it.

A heart or club lead (bigger than the 2) from W will beat 6N, but not from E which is why 6N= is par

The aim should be this one but untill now we have 11 tricks.

You've completely not understood what is going on.

 

If W discards down to this on the final diamond, we pitch J (not a club) and play a club making 12 tricks.

I have told so because I think that the ending should be another one. At 6th trick we have in heart also 4 as card. How has told PhilKing is just that 7 in club forces W to retain three cards but when an heart is discarded by W becomes idle because this ending should be a whinkle (with a ruffing) a trick before.The situation in club (AQ) forces E to lead always in heart plus it needs to avoid throw-in. Infact little to Ace and unblocking(=King is leaded), 4 for 10 to Q and W cannot play in suit than club to A, the now winner J pitching a club and Queen ruffed by 7.
