Vugraph from China the other day. The theme is suit combination. Many beginners and/or intermediates would not even think that there is a problem in the spade suit, and there would not be most of the times. There is no problem if the suit breaks 2-2 or 3-1 (90% altogether), but there is if spades break 4-0.
There is nothing you can do if West has all four; then he must come to a trump trick. No need to worry about something you can do nothing about. If East has four, however (half of the times spades are 4-0 = 5%), you can pick them up if you play carefully.
After winning the diamond in hand at trick 1, it is essential that declarer plays a
low trump from his hand. If he cashes a top honour, he must lose a trick and the slam goes down.
At trick 2 it transpires that East indeed has all outstanding trumps, but he is not entitled to a trick because you were aware of the danger. You win dummy's king, play a low spade back towards your hand and win as cheaply as possible (East will likely split his remaining J108).
Now you cash the other top diamond and ruff a diamond in the dummy. The last trump from dummy leaves East with no good answer. His Jack and 8 are under your Q9.
Let me change one card and give dummy
♠10.
K1053
AQ964
With this combination it is correct to cash the ace or the queen first, because when you have the 10 in one hand and the 9 in the other you can pick up the 4-0 regardless who has four. It will be revealed after you cash the top honour and now the jack is finessable no matter who has it.
On the actual layout there is still one danger though. When you pull East's last trump, dummy is out of trumps (remember that you ruffed a diamond earlier). Now it's important that you discard a
club from the dummy,
not a heart. You may need the guarded
♥K later.
You give up on the overtrick but that is not important at IMPs. If clubs break 4-1 (and they did as you see), you must rely on
♥A to be onside, and then it won't help if you have bared the king.
Cash
♣KQ, get the bad news in the club suit too and finally lead a heart towards Kx. 12 tricks, 1430 in.
I am happy to say that declarer, Liu Jun, played the hand exactly like this, card by card, and was rewarded with 13 IMPs when NS in the other room stopped in 4
♠ (11 tricks).
Vugraph is not only entertaining, it is also a great place to be when lessons are to be learned. This is an excellent example in my view.
