Throw Your Winner!!!

In a recent tournament, I found an interesting board as displayed below. The bidding is using precision system, South open 1D, North 1H, South rebid 1NT (12-14) and North jump to 3NT. West lead spade, Declarer hold up for 2 round and win the 3rd round while discarding heart from dummy.
Dummy
♠ 7 6
♥ 10 6 5 4
♦ A K Q 10 9 5
♣ 6
You
♠ J954
♥ K92
♦ 43
♣ A J 43
Contract 3NT. Declarer then run 6 diamond tricks, what's defensive plan?.

A novice defender will give an encourage signal for heart by discarding the ♥9 and then leave the ♣ A alone. Declarer then exit with club to west, who cash the spade and has to play a heart to the fork. Even if declarer can read the position correctly, west actually could beat the contract.

Here are the logic.

West is the victim of the end-play. If declarer hold the ♣K outside of ♥AQ, nothing can be done. Contract can't be beaten. However if declarer just has the ♣Q instead of ♣K, then can throw his winner and retain the ♣Ax. He will win with ♣A and play club to east ♣K who will play the heart through declarer. So, sometimes the winner shall be threw. Here are the complete distribution

♠ 7 6
♥ 10 6 5 4
♦ A K Q 10 9 5
♣ 6
West East
♠ J 9 5 4 ♠ K Q 3 2
♥ K 9 2 ♥ 873
♦ 4 3 ♦ 76
♣ A J 4 3 ♣ K x x x
Declarer
♠ A 10 8
♥ A Q 6
♦ J 5 2
♣ Q 10 7 2

Play According to Contract

Indonesian Bridge League, a new way to select the team to represent Indonesia has just been started last week. In qualification round, we found out the distribution below. Most contracts were 6♦, and one pair reached 7♦.
Dummy
♠ A J 7 6
♥ A 6
♦ A J 5
♣ A K J 6
Declarer
♠ K 5
♥ 9 2
♦ K Q 10 9 3 2
♣ 7 4 3
Contract 6♦. On the bidding, North started with strong (1♣ precision, or 2NT ), East overcall with 2♥. The slam was played either in South or in North.

I was a declarer in the South and received a ♥7 as opening lead. I play the Ace and keep the ♥9 in my hand. Draw 2 rounds of trump, which divided evenly. I continue to play a small heart from dummy, lucky me as East play the ♥J, and won the trick and at the same time was threw-in. So, I claimed immediately.

In case East played small and West won with ♥10, I would be on test. How do you execute in case West play a small club? There are 2 reasonable ways to fulfill the contract. First play 2 rounds of club, if the queen does not fall, you have to finesse the spade. Other choice is to try to ruff the spade, when the queen falls, you are home. If the queen is still there, then play all of your remaining trumps and decide how cards are distributed outside.

Franky Karwur, one of Indonesian top bridge play were facing a grandslam in diamond for the distribution above. How will you bring home the contract when heart as opening lead?

After winning the heart lead, Franky played the ♣A, when ♣10 drops, he countinued with the King. Wow... the ♣Q fell down. Franky then played 3 rounds of spade and ruff it. When West has a Queen guarded, he claimed for a simple squeeze. A logic play from one of Indonesian top bridge player. Congratulation Franky.

Here are the complete distribution

Another Interesting Hand

In favorable vulnerability, right hand opponent open with strong NT (15-17), I hold ♠ 3 ♥Q 3 ♦AKJ873 ♣ 9763 and overcall 3D. All pass. West started with ♥5. Plan your play!
Dummy
♠ Q J 7 2
♥ 10 8 7 2
♦ 6 5
♣ A Q J
Declarer
♠ 3
♥ Q 3
♦ AKJ873
♣ 9763
East won with the ♥ K and switch to a small diamond. Not knowing the position of high cards yet, I chose to play the Ace and continue with club finesse. East won with the King and return a small spade. This return will bring home the contract. Won with the ♠ A, West return another club. Here the position after 5 tricks and defender has won 3 tricks.
Dummy
♠ Q J 7
♥ 10 8 7
♦ 6
♣ A
Declarer
♥ Q
♦ KJ873
♣ 97
How do you continue? Ruffing finesse spade for club discard? Not logic. If you want to do that it means club divided evenly. So finesse diamond, draw one more round of trump and play heart. East was end-play. Here are the complete hand
Dummy
♠ Q J 7 2
♥ 10 8 72
♦ 6 5
♣ A Q J
West East
♠ A 10 6 5 ♠ K x x x
♥ J 6 5 ♥ A K 9 x-
♦ x x ♦ Q x x
♣ 10 x x x ♣ K x
Declarer
♠ 3
♥ Q 3
♦ AKJ873
♣ 9 7 6 3
The interesting aspect is when East return club at trick 4. Won in dummy, finesse a diamond then declarer play a spade. If West follows the rule of second hand low, he gives declarer the contract. West will be squeezed in 3 suits: club, heart and spade.
