Great Defense

Playing with or against world class players creates interesting moment and feeling. I had an opportunity to play with Indonesian national player, Taufik Asbi in Alex Frans Memorial Invitation Pair on April 2006. Previously, we played together when Taufik was still a student in Bandung, a nice city around 180 km east Jakarta.

This board will show the interesting moments, both in defensive play, the hardest part of bridge game because of both defensive player are involved.

The role play on this board was Ferdy Waluyan, previous famous Indonesian national player. This board showed Ferdy's capability in defense to make life difficult for declarer.

Contact died at low level 2H with no opposition bidding, North 1D, South 1H and North raised it. West opening lead was ♣3. Below are the complete distribution.

East, Ferdy won the first club, and switched to ♦8, ♦Q, ♦K and ♦A. Next club won by west who cashed the ♦J and continued diamond. Declarer ruff and run ♥J, but East won with ♥Q. A critical moment arrived. Let's think for a while. Knowing that declarer hold 2425 along with bad spade position for defenders, Ferdy returned a killing defense double void diamond. This is the only defense which might defeat the contract.

Declarer will setup club on heart attack. Spade return, playing the correct card will make 9 tricks. Event when declarer played the wrong spade, declarer will still land their contract by setup his long club and used their trump as entry.

With diamond return, declarer lost his control. He can not setup club anymore. It needs a careful play to fulfill the contract. There are two ways, correct placing the ♠K or the ♥9. If you placed ♠K in East, after discard club in the hand, ruff in dummy, you may play spade to Queen. As the cards lie, this plan was fail. If you place the ♠K with West, after ruffing the diamond in dummy, draw all trumps and play ♣J and club, throw West in. For all declarer who count the high card point on both defenders, you may find that both of them may have the ♠K.

There is another way to land the contact by placing the ♥9 in the West. After ruffing the diamond in dummy, discarding spade in his own hand, Taufik played ♠A and spade ruff. club ruff with ♥K and another spade ruff. He continued with club to be ruffed with ♥8, en-passan. Unfortunately, East hold the ♥9 so contract failed. Congratulation for defenders.

Second Degree Assumption

Second degree assumption was popularized by Terence Reese, a great author of bridge book. I found out this theme during the Frans Waleleng Invitation Pairs last week in Jakarta. At love all, the bidding run as below:
SouthWestNorthEast
1H2D3H (weak)pass
4HXall pass
West started with ♦A and continue with ♦K when East signal with ♦10. Here are the cards.
Dummy
♠ 105
♥ Q986
♦ 432
♣ J954
Declarer
♠ AJ43
♥ A10754
♦ 8
♣ AQ3
How do you proceed? In order to succeed you need to place the ♣K on East. When West make a double on his own hand, you shall place all of high cards in his hand. Another assumption is ♣10 shall be with West, you will fail otherwise. When you ruff the second diamond and lay down the ♥A, West follows with ♥K. What next? A small heart to Queen, followed by diamond ruff, close the exit card. Then you play a small spade. West will win and end-played. Below are the complete distribution.

Club return will solve declarer problem, then West return spade. Assume West return ♠K. Declarer win with ♠A and cash ♠J to discard a club. Spade ruff. East may be overruff but he will be end played. If he discard club, then declarer will land his contract with 3 club tricks. If he parts with diamond, he will throw-in with heart. A nice board.
