The rule for third player to a trick
Work through how the play is likely to go if you perform a particular action. As each
trick is played and you gain more information, you must continually revise your defensive plan in the light
of what you have observed. Third hand plays high, the usual mantra for the defense - meaning when you are
playing the third card to the trick and you are on defense you should in most situations play a high card
Definition
You are defense and your partner leads a card, this puts you in the position of playing third to the trick, this is when you play your high card. There are exceptions but on the whole it is a good piece of advice.Examples of Third Hand Plays High
Partner leads the 4 and dummy has T 7 2, dummy plays low and you hold any of the following cards- A 5 Play the ace
- K 9 6 Play the king
- A Q Play the ace
- J 8 4 3 Play the jack
- 4 3 Play the 4 and partner will know you have nothing better
The Problem
There are exceptions to the "third position plays high" ruleException 1
If your partner on lead plays an honor for example a jack or queen, dummy plays low, and you have the ace , you should cover and win the trickPartner leads the queen and dummy has 965 and plays low, win with the ace if you have one
Partner leads the jack and dummy plays low from T85, again win with the ace if you have one
Exception 2
If you have touching honors/cards, play 3rd hand "high," but with the cheapest in the sequence in your hand For example, partner leads the 2 and dummy has 9 8 4- A K 7 Win the king, not the ace
- K Q T Play the queen, not the king
- A Q Play the ace
- Q J T 9 Play the nine, the cheapest in the sequence
Exception 3
If dummy one of the top three honors and you have a higher honor and dummy plays lowl withhold your honor and try to finesse with an intermediate card if you canFor example:
- Partner leads the 4 and dummy has Q 8 7 and plays low. You should play the Jack holding K J 2 or A J 2
- Partner leads the 2 and dummy has K T 4. You should play the 8 from A J 8 3
Let’s look at some examples
Assumes fourth-best opening leads.4 3 2
A 10 9 8 7 K J 5
Q 6
1. ) West leads the 10, the top of a sequence. East must go up with the King, otherwise declarer South will win the trick and switch to another suit.
K 9 7
A 8 3 2 Q 10 4
J 6 5
2. ) West leads the 2, the fourth best and promising a four card suit (otherwise West would lead a higher card, holding. After declarer plays the 7 from dummy, East must play Queen, otherwise South unnecessarily wins a cheap trick.
8 7 6
K 10 4 3 Q 9 2
A J 5
3. ) West leads the 3, the fourth best - as East, you can deduce this fact since you hold the 2; if West held 5+ cards, the lead would have been a card above the 3. In third seat, East must play the Queen, again third hand high in order to hold the declarer to one winner.
