Think Fast
I generally feel happy if I make one good play per session. Which is a good thing, because it was in an otherwise disastrous pairs session that this deal came up:

A long string of clubs in dummy, but I have the Ace, and if we can establish our diamonds we should get five tricks before they can get nine. It all depends on how strong declarer’s diamond stopper is.
I encourage partner with the  6 
  and declarer plays the 4. Partner continues with the
6 
  and declarer plays the 4. Partner continues with the  J 
  and I duck again, as does declarer. Does partner have another diamond? Yes, 
  happily he plays the 3 and I take my Ace. I return the
J 
  and I duck again, as does declarer. Does partner have another diamond? Yes, 
  happily he plays the 3 and I take my Ace. I return the  2 
  and declarer wins perforce with the King, partner discarding a small heart. 
  That leaves:

We have three tricks in and presumably declarer will have to 
  play at least one club, so I can just take my  A 
  and my remaining diamond to set the contract.
A 
  and my remaining diamond to set the contract.
Declarer indeed leads a club, and partner comes up with the Jack. Declarer calls for the King and my hand is moving toward the Ace when suddenly a bell goes off.
Partner played the Jack! If I take my Ace now, I’ll set 
  the contract with the  9, but then I won’t 
  have anything else to cash. Setting the contract is always tempting, but if 
  I duck, then, with the
9, but then I won’t 
  have anything else to cash. Setting the contract is always tempting, but if 
  I duck, then, with the  J gone, I’ll have
J gone, I’ll have  A10 
  behind dummy’s Queen, and if declarer, in an attempt to make his contract, 
  leads another club toward dummy, I’ll be able to set him two. 
  And this is matchpoints.

  behind dummy’s Queen, and if declarer, in an attempt to make his contract,

  And this is matchpoints.
My hand is still moving toward the  A. 
  If I duck, will I be giving declarer the last trick he needs to make his contract? 
  How many spade tricks does declarer have? No time to think about it! If I’m 
  going to fool declarer into thinking that partner has

  I have to act fast. I should have counted declarer’s tricks earlier. 
At the last possible moment for a smooth play, I slightly change 
  my hand’s direction and pluck out the  8. Declarer 
  hmms, thinks, and then goes back to his hand with a spade to the Ace and cashes 
  the

  the  K as well, discarding a club from dummy and

“I could have cashed out for down one!” declarer wails.
Plus 100 is worth 9 out of 12 matchpoints, and plus 50 would have been only 4, so ducking gained nearly half a board.
