Playing to the first trick or two can be critical. Below are three hands where early play is the key to success.
Hand One

West leads the 6♣️. Dummy plays 2♣️ and East plays 3♣️. What is your plan?
Hand Two

You lead A♥️. Dummy plays 4♥️, partner plays 6♥️, and declarer (East) plays 2♥️.
What is your plan for the ♥️ suit?
Hand Three

West leads the 10♦️. How do you handle the ♦️s?
HAND 1: presume W has led from 4 to the Q. Take the first trick with the A. Then play A Ds, then play a small C to the 9
HAND 2: If partner plays the 2H at trick 1 I presume p has either Q hearts or a singleton. I would lead 3H at trick 2
HAND 3: Presume that the lead of 10D is quite possibly a doubleton. Therefore presume that E has the K and Q Ds and will cover the J. Your 9 D should be a stopper after you lose the A Hs
Well done P – good stuff!! Hope I’m right 🙂
