Two-Way Finesse

A two-way finesse is a card combination in which either defender can be finessed for a queen:

	Dummy
	AJ43
West		East
???		???
	South
	KT92

In this layout, South can cash a top spade in either hand and then finesse for the Q.

Several factors may influence South's decision:

Counting the points and distribution around the table may swing the odds of finessing in either direction.
An endplay might force a defender on lead, thus eliminating declarer's guess.
An avoidance play may be necessary for declarer, if it's too dangerous to finesse into a particular defender.
Table presence or "feel" may help declarer determine which way to finesse.

Examples

Counting the suit distributions or high card points during the play of the hand may help declarer, as in the following deal.

		Dummy
		AJ95
		65
		AQ76
		J32

		South
		KT7
		974
		JT42
		AK4

South passes partner's game invitation but still ends up in trouble. West's opening lead is the 3, won by East with the K. East continues with the A, J and low heart to West's queen.

At trick 5, West leads a low diamond. South finesses but East wins the K and plays back the T.

At this point, South must either :

Duck and play East for the Q. This is unlikely - barring a Grosvenor gambit, East probably would not lead away from Q-T with the J in dummy.
OR
South must guess spades to make the contract.

South has an additional clue to inform the decision. East has already shown up with 11 HCP, yet passed in first seat. Holding either black queen as well, East would have 13 HCP and would probably have opened the bidding. Therefore, South should rise with the A and play West for the queen of spades.

The complete deal:

	Dummy
	AJ95
	65
West	AQ76	East
Q83	J32	642
QT83		AKJ2
53	South	K98
Q765	KT7	T98
	974
	JT42
	AK4

An endplay can also obviate the need for guessing a two-way finesse. For example:

		Dummy
		64
		KT9
		JT92
		AKQ3

		South
		AJT2
		AJ8
		AKQ
		J65

South plays in 6NT and receives a T opening lead. There are 11 top tricks, and a 12th is possible if South guesses hearts correctly or takes a successful double finesse in spades.

However, the 12th trick is guaranteed if the minor suits split normally. South wins the opening lead and rattles off all the minor-suit winners, finding both suits 4-2. Having finished in dummy, South can now lead a low spade to the jack. If this loses, then West is endplayed in the major suits. The full deal:

	Dummy
	64
	KT9
West	JT92	East
KQ98	AKQ3	753
Q63		7542
65	South	8743
T987	AJT2	42
	AJ8
	AKQ
	J65

An avoidance play might also be necessary if declarer can't afford to let a particular defender gain the lead, as in the following deal.

	Dummy
	87
	AK54
West	KT98	East
KQJ93	432	642
J9		QT62
Q64	South	73
T85	AT5	J976
	873
	AJ52
	AKQ

Naturally enough, West begins by leading spades, South winning the third round.

South can count 8 top tricks. A 9th trick can be created from the two-way finesse in diamonds. However, it is vital for South to finesse West for the Q, not East. If South cashes the A and runs the J, East might win with the Q, but won't have any spades left.

If South instead cashes the K in dummy and runs the T, West might win the Q and plunk down two more spades to defeat the contract.

Lastly, table presence may also influence a two-way finesse. Two bridge stories involve the late American expert Hal Sims:

"The legendary American Hal P Sims, a champion at many other sports besides bridge, was famed for his ability to guess which of his opponents held a crucial queen. He would rely primarily on what is called 'table presence' (he was an excellent poker player in addition to his other talents). One day, some friends rigged a deal... both opponents held a queen of spades! Sims won the opening lead and thought for some time. Finally, he exploded: 'This is impossible - you've both got the queen!'" ¹

The second story involves a much more cunning approach:

"Once, when faced with a two-way finesse, Sims turned his formidable gaze on his left-hand opponent and declared: 'You look like a lady with the queen of spades.'

"'Oh, Mr Sims,' gushed his victim. 'Aren't you wonderful!'" ²

A third story involves the late American expert Barry Crane. As told by Grant Baze, it's more superstition than table presence but is still worth sharing.

"Barry had several superstitious rules that he followed always, and his partners better follow them or all hell would break loose. One of these was that if you had a two way guess for a queen, you did not have to think about it — the queen was over the jack in the minors, and under the jack in the majors. So if you held Axxx and dummy had the KJ109, you would lay down the ace and lead to the J if the suit was a major, and lead to the King and finesse coming back if the suit was a minor.

"Barry and I wind up in 7NT and that was our club holding, with only 12 top tricks; we each had balanced hands so I did not expect to get a count on the hand. No problem, I'm thinking to myself, I will not be able to get a count on the hand so I will just follow Barry's rule; if it does not work at least he will keep his mouth shut. I cash a few side suit winners; to my annoyance the suits split crazy and I do get an exact count on the hand. LHO has three clubs and RHO two clubs, which makes it a 50% better play to ignore Barry's rule.

"Meanwhile, at the same time, downstairs in another section, Mike Smolen is playing this hand at the same moment; he knows he and I are playing this hand simultaneously. Mike also gets a count on the hand, but decides to follow Barry's rule. Sure enough, the Queen was doubleton and Mike makes the hand. Mike knows I am going to guess the hand the technically correct way, regardless of Barry's superstitions; Mike tells his partner 'Listen closely, you are about to hear an explosion from upstairs.' How right he was. I misguessed the Queen and Barry went ballistic, screaming like a lunatic and then running out of the room....

"Parenthetically, for the rest of the day Barry and I kept track of how often his rule was right; to my shock, in the relevant situations, it was right five of six times. I am telling you, Barry was mystic; there is absolutely no reason it should not be a 50-50 proposition. Nevertheless, to this day, if I have no clues as to which way to finesse in these situations, I just follow Barry's rule." ³
