A from AK. Ins and Outs explained

Hi Folks,



The above treatment has caused an appreciable amount of problems in my bridge experiences so I thought I’d write a definitive explanation of the subject. Hope you enjoy the discussion.



First, last I checked, K from AK is still standard. So, if you’ve decided to juxtapose this lead agreement, please don’t explain your treatment as “standard”. This almost caused a committee hearing once, so remember, K from AK is standard. If you lead A from AK your treatment is not “standard”.



So why do lots of pairs reverse the standard K from AK treatment? We reverse this lead so we can distinguish the AK from KQ leads. This is extremely helpful when playing standard carding and you hold something like J7. If partner leads the A, you signal high low for the third round ruff (hopefully you have trump). If partner leads the K promising the Q you might not want to blow all your honors on the first trick. At any rate, if partner leads the A promising the K you usually give attitude for the Q or a ruff. If partner leads the K from KQ you give attitude for ruffs or the J but know that you have to wait for one control card to disappear –namely the A. It’s probably with opponents.



In some very specific situations, one often leads the A w/out the K. Now what? Leading A from AK precludes the partnership from knowing whether that A is backed by the K or not. It isn’t often that we lead an unsupported ace except in the following situations:



1) At the five level or above

2) When you’ve bid and raised your suit

3) In the middle of the hand and

4) Against preempts at any level.



Example: Your partner and you have raised hearts. The opponents have violently competed in spades. Wouldn’t you lead the A without the K. Often you would. If you insist on using your A from AK agreement, your partnership will not be able to give attitude towards the K. This has happened several times in my partnerships. Partner led the A, I presumed he didn’t have the K and carded accordingly. Confusion ensued.



In these situations it’s more important to know that your partner has led a blank ace then it is to distinguish K from KQ. Why? As noted above, reversing standard treatments helps you negotiate J7(3) –like holdings. Now tell me, how often is that an issue at the five level or above, when you’ve bid and raised your suit, in the middle of the hand or against preempts. Jacks usually don’t cash in these situations.



Hope this is helpful. There is one other time one leads K form AK. That is when you have AK dry. Partnerships just have to figure that one out from the bidding and from the trump holding.



Have fun.
