Hand Evaluation - Visualization ( Intra-finesse )

PITBULLS:

When you have the patterns memorized , you can “Think in Patterns” . This allows you to make some advanced plays with card combinations because you can “visualize” the opponents holdings in the suit. One of these advanced plays is the “intra” finessse. Intra is from Latin meaning within. In the Bridge sense , this means that you are finessing within two honours. The intra finesse always involves a 2^nd round smother or pinning play. Here is an example.

	Q 8 5 3
J 7		K 10 4
	A 9 6 2

The bidding has given you quite a good idea of the layout of this suit. To hold yourself to one loser, you play small towards the dummy and finesse the 8! East will make the 10 but later you will enter the North hand and lead the queen, pinning West’s jack. Well, this was an Intra-finesse.

‘Here’s how an Intra-finesse can arise in practical play:

		♠	Q 9 2
		♥	6 5 4
		♦	A Q 3
		♣	K 8 4 3
♠	10 6		N		♠	K J 7
♥	10 9 8 2		W	E	♥	A K QJ
♦	5 4				♦	10 9 7 6
♣	10 9 7 5 2		S		♣	Q J
		♠	A 8 5 4 3
		♥	7 3
		♦	K J 8 2
		♣	A 6

‘South plays in four spades after East has opened a strong no-trump. West leads the ♣10 and South ruffs the third round. Knowing that East has the king of spades, South leads low to the 9, losing to the jack.

‘South wins the club return and takes a second and third round of this suit to test the distribution. With East showing out, South decides to place him with three trumps. So, after ruffing the third club, he crosses with a diamond and leads the queen of spades.

‘A veteran intra-finesser now, you find yourself in four hearts on the next deal after a club overcall by West.

		♠	K J 2
		♥	A 9 2
		♦	K 9 6 2
		♣	9 6 3
♠	8 6		N		♠	10 9 7 5 4
♥	J 5		W	E	♥	Q 10 7 6
♦	Q 10 3				♦	8 4
♣	K Q J 10 8 7		S		♣	5 4
		♠	A Q 3
		♥	K 8 4 3
		♦	A J 75
		♣	A 2

‘You duck the first club and West continues the suit. As a 3-3 trump break is unlikely, you lead a low heart towards the dummy, and when West follows with the 5 you finesse with the 9!

‘East wins with the 10 and switches to a spade, confirming that the clubs are 6-2. You cash the trump ace, and when this collects the jack from West you pick up East’s remaining trumps by finessing the 8.

‘On the fourth trump you throw, not a club, but a diamond from dummy. The successful intra-finesse has brought you to 9 tricks but now you must establish a diamond game.

‘As you are wide open in clubs you lead a low diamond, intending to finesse the 9 into East’s hand. West, however, inserts the 10. You win with dummy’s king and cash the remaining spades. When West shows out on the third remaining spade you have a perfect count. West began with six clubs, two hearts and two spades – and therefore three diamonds.

‘You need no more finesses. On the third spade West is forced down to two diamonds and the jack of clubs. You therefore lead dummy’s losing club, throwing West in and forcing him to lead into your diamond tenace.

‘This ending was very satisfying – but you would never have got there without the aid of an intra-finesse in the trump suit.

There are many variations of this theme. Most players know what to do with this combination:

J 9

A 8 7 5 4 2

The only chance to hold the losers to one is to lead low and finesse the 9 (unless West plays an honour). If this loses to the king or queen in your next play is the jack from dummy, pinning the 10 if West started with 10-x.

When two intermediate cards are missing you can achieve surprising results when both are favourably placed:

	J 9 4
10 8		K Q 6 3
	A 7 5 2

You lead low from hand, covering West’s 8 with the 9 and losing to the king or queen. On the next round you lead the jack, pinning the 10, and you still hold the major tenace, 7-5 over East’s 6-3. It may be noted that in many of these situations it is good deceptive play for a second hand to play his higher card on the first round, just as it is usually correct to play the jack from J-9.

South	West	North	East
	Pass	Pass	1♦
Dble	1♥	Pass	Pass
2NT	Pass	3NT	Pass
Pass	Pass

Spurning his partner’s suit, West leads the ♥6. East wins and returns a heart.

Assuming that the diamond finesse will be right, South needs to make four tricks in clubs. Because of the entry situation, he must lead the jack of clubs – no other card. Having overtaken the jack with the ace, he leads the 10, unblocking with the 8. Then he can make four club tricks and still be in dummy for the diamond finesse.

Here is an extremely difficult hand with the same theme :-

West begins with ace another spade. How can South make his contract of five diamonds? Even with a sight of all the cards, you might battle at this for hours without striking the right answer.

Everything hangs on the pips in clubs. South wins the second spade in hand, discarding a heart in dummy and noting East’s echo. If West holds two clubs, or the singleton 10 or queen, the contract is laydown, because declarer can pick up the trumps without loss and make three tricks in clubs.

The critical situation is when West has the singleton 7 of clubs. Preparing for this, South leads ♣8 at trick three. Seeing West’s 7, he plays low from dummy. East wins with the 10 and exits with a heart to dummy’s ace.

Declarer now plays diamonds until East covers. South wins and leads the ♣9 to dummy’s king. Now, with J-6 of clubs in dummy, A-3 in hand, he can pick up East’s Q-5 and still be in a position to finesse in diamonds.
