Suit handling, the hunt for the queen
Suit handling when you are missing the queen :
If we assume that communications are nor an issue, depending on the number of cards held by your camp and on the honors held, you shall use one of the maneuvers below :
If we assume that communications are nor an issue, depending on the number of cards held by your camp and on the honors held, you shall use one of the maneuvers below :
- If your camp has 9 cards led by Ace King , you'll draw them upfront hoping for a 2-2 beak ot he remaining cards 2-2 (probability 40%...to which you should add the odds of the queen singleton (12,5%,)
- with fewer than 9 cards, the finesse is best the probability it works is roughly 50%..but it is not always possible : You need a tenace in one hand or consecutive cards in the other.
- with fewer than 9 cards, you may sometimes increase the propability of success of your maneuver By starting with a high honor (probe) before going for the finesse

Exercise 4665 : With 9 cards in your camp do not finesse the queen. Draw the Ace and if both opps follow, then draw tour king
Note:
- With fewer than 9 cards in the suit, directly try the finesse
- If you can play a probe whilst still being able to finesse on the 2nd round... Do it...
- Play a high honor first in a way that preserves your tenace
- With 9 cards, play Ace, King and Queen upfront Star with the honor that preserves your tenace
- If the play situated after the tenace does not follow, you'll play the obvious finesse on the second round

Probabilities
The probability of Queen in singleton : 50%*(1/4) =12,5%
Probability of 2-2 (that necessarily includes the queen: 40%).
The chances of success adds both, or 52,5%So with 9 cards led by Ace King , It is preferable to Draw Ace King, rather than try the finesse ...Even more if you consider that with a 4-0 break (10%) you may still be able to capture the Queen with a finesse .
- With fewer than 9 cards, it's easy...The finesse has a 50% chance of succeeding !
- With 9 cards
- Split Probability
- 2-2 - 40%
- 3-1 - 50%
- 4-0 - 10%
