Attitude on Opening Lead --the Plot Thickens

So you've agreed to play "attitude on opening lead". It's a pretty standard treament and most experts can field it even though it may not be their preferred method. I play nothing else, but know that even this standard treatment takes a lot of work.


The comments that follow refer to standard carding against suit contracts. Upside down carding is relatively the same with some minor twists.

So, positive attitude means you want the suit continued, and you "echo" with your suit. Holding 87 and wanting a ruff, or not wanting a shift, you play 8 followed by the 7. If you do not want a ruff, there is no reason to "echo" in the suit. Ask for a switch by playing the 7. If you wish the suit continued and you hold 973. Play the 7 (continue) then play the 9 --now switch.

As per usual in bridge when it concerns carding, the plot thickens fast.

Suppose you hold Ax, Kx, Qx, KQ, or QJ. Now what.

With Ax, you should only be concerned about overtakingthe K --should you overtake and ask for a ruff by returning your small card? Usually that is a good idea. However if you're staring at Jxxx in the dummy and you have a natural trump trick, why would you overtake and ask for a ruff. That might be crashing your tricks in order to set up dummy's suit.

The general principle with Kx and Qx is that one generally should not signal with an honor if there is a reasonable chance that it is needed for tricktaking purposes, i.e., if playing the honor is likely to reduce the number of tricks that you and partner can take.


So, if you hold Kx and partner leads the A, play K only when the K ranks to block the cashing tricks. You don't want to be stuck with Kx in your hand and let declarer run the rest of the tricks. Consider a hand where partner shows 5 good spades and is unlikely to have a quick side entry (for example, dummy has 1st round control of the other suits) and dummy has xxx in spades and top cards in another suit that are likely to provide quick pitches. Or perhaps you are defending 5m at IMPs and can tell that the only tricks for the defense are likely to be in spades. Now it might well be right to play K from Kx so hopefully the defense can cash 3 quick tricks, which would be impossible if one held onto the K.

If you don't see that happening, play low and let partner figure it out. If you pound the K in situations where blocking and cashing are not issues, partner is going to think you have a singleton and underlead. Oooops.

Playing the Q on an opening lead of A or K usually promises a singleton or the J.
So unless you're dire for something to happen, play low from Qx. Partner will underlead if he/she wants you in for a timely return through declarer's values. He/she thinks you hold the J with your Q, or that your Q is singleton.

Most folks echo with Jx if they wish to show partner a doubleton or want a ruff for some reason. Jx's usually don't compress tricks if the J is blown on another top honor. Playing the J from Jx would be appropriate if one wants the suit continued for a ruff, or in a count situation, if playing standard carding. But if one does not want to ruff (from one's natural trump trick, perhaps) or if partner leads the K showing the Q and not the A, and dummy has 10xx, then generally one should not play the J from Jx, because it will cost a trick.

Hope this is helpful. Ask if you have questions.
