Hi,

It seems to me that we can play 3 rounds of  in hand, keeping the king as entry, and a small to the 10. Now, East has to give me the 9th trick (at least).
What's wrong with this line?

Regards,
TS

No, i don't win. I play a small from my hand. Now, if west play the Queen, the Jack of is my 9th trick. And if West play small, the Jack of is also my 9th trick. In either case, i have no entry problem. For example, suppose West win the switch with the Queen and lead another . I win with the Ace, play a small to the J (or to the K ) and after this i return in hand with my third (or K of to the Ace) and i'm OK : 3, 5 and 1 .

TS

PS : apologies if i'm not clear because of my english but i really don't see the problem with this line of play.

Nor do I, it's a much simpler solution than the intended one though probably not as nifty.
Please let me know about any questions or interest or bug reports about GIB.

No, it isn't - since you have not established any Diamonds yet.

E-W can establish 4 tricks in the majors before you can knock out the Diamond Ace.

There is ALWAYS some combination of major suit honor placements that can defeat you. You CANNOT make the contract by merely cashing 3 clubs and then trying to force an entry to dummy.

Your line of play will FAIL given my set-up. Your spade entry coes too late, since the opponents set up and cash 3 hearts and a spade (or 2 spades and 2 hearts) to go along with their Diamond Ace - which you have not driven out.

"If EAST ever wins a trick, they return a small spade"

"3 rounds of CLUBS and then a HEART is not good enough, since any continuation can be defeated if the cards lie badly"


After cashing 3 clubs in hand, lead Heart to Queen or Ten, East is endplayed in 3 suits after winning King or Jack and must give dummy the 9th trick

3NT by North seems to be a better contract. Any non-club lead gives 9 or ten tricks (maybe 11)

1-3NT  :)

Tony

No, he is NOT endplayed. He wins the heart and returns a SPADE. IF you duck it (establishing the JACK as a dummy entry), West wins and returns a second heart. West - with an original holding of K-J-10-X - forces out your Ace of hearts and now holds 2 heart winners AND THE DIAMOND ACE (which you seem to forget is still at large, you having failed to establish ANY diamonds winners yet.)

1 SPADE, 3 HEARTS - 1 DIAMOND. 5 tricks. DOWN ONE.

You CANNOT fail to establish your diamond tricks and make 3NT - and you have to waste a dummy entry to establish them.

But the act of establishing them without trowing a CLUB WINNER from your hand destroys any chance of forcing a later entry to dummy - as the original problem demonstrated.

Scoring: IMP

That's impossible. No one can give more than one hundred percent. By definition that is the most anyone can give.
