Declarer's Arch

Yes, that's Delicate Arch in southern Utah, but today we're talking about Declarer's Arch. Or more accurately, Declarer's ARCH; it's not in Utah.

Playing matchpoints, nobody vulnerable, you are the dealer.

West leads the 7. Your play?

ANSWER: Which card you play here doesn't matter much. But did you remember to ARCH ?

THE PRINCIPLE: Before playing to the first trick, take a few moments to think the hand through.  A handy checklist is the acronym ARCH: Analyze, Review, Count, How.

  • ANALYZE the lead; Is it from an honor sequence, or fourth best from length, or a doubleton, or a singleton, or something else? 
    • With only the J and 7 of diamonds missing, it looks like a singleton 7.
  • REVIEW the bidding: Did the opponents bid or not, and what does that suggest about the shape and values of their hands? 
    • West overcalled hearts at the two-level, and East raised only under duress. West didn't bid 4. Most of the missing high cards (and there are lot of them!) must be in West's hand. East has long hearts and almost nothing else.
  • COUNT your tricks: At suit contracts, it's usually more effective to count losers; at notrump, count your winners. 
    • I have a spade loser, two club losers, and maybe a diamond loser but only if West led the 7 from J 7, which doesn't seem likely. Making four looks good, and there's a chance for five.
  • HOW will you play: Plan at least a general strategy before playing to the first trick. Will you draw trumps, postpone drawing trumps in order to cross-ruff, try to set up a side suit, or ?? That strategy may affect your play to the first trick. 
    • I will lead spades to punch out the ace, when I get back in I'll draw the remaining trumps and run the diamonds. If they don't take both of their club tricks right away, I'll discard a club loser on dummy's sixth diamond. If I play the Q smoothly to the first club trick maybe they'll be persuaded to switch to hearts instead, and I make an overtrick.
So before playing from dummy at trick one -- even if it's a singleton -- remember Declarer's ARCH. Analyze the lead, Review the bidding, Count your tricks, and plan How to play the hand. It wouldn't hurt to arch your back, too; being hunched over all the time is bad for your posture :)
