AJx
Q987x


Plenty of entries, you need 4 tricks.

Please someone explain why Suitplay gives the following solution (in hidden text) ?

The interesting original holdings if the J makes the 1. trick were:

Kx_______10xx
K10______xxx
Kxx______10x
K10x_____xx
Kxxx_____10
K10xx____x

You always catch the 10.

If the J loses, the original holdings were:

x________K10xx
10_______Kxxx
xx_______K10x
10x______Kxx
10xx_____Kx
xxx______K10
10xxx____K (only in this case running the 9 is as good as playing the A in trick 1).

By cashing the A next time (2. round in this suit) you deal with every 3-2 distribution and all 4-1 distributions without the stiff K.

Running the 9 in trick 1 is not a safety play to my opinion, loses much more often than playing to the J.

i don't quite understand.. someone says running the 9 is best for 4 tricks? seems to me that low toward the jack is... if i *have* to take them all, maybe running the 9 works out, i don't know

Running the 9 you can loose a trick to the 10 and to the K.
If you play to the J the 10 will not get the first tricks.

If the J holds there is a good chance that LHO holds the K. If LHO has the T too, you will now capture one of them 4 sure.
If you loose the 8 to the RHO's T, he had 2 cards, so LHO holds 3 cards und you will catch the K for sure.

If the J is taken, you hold AQ to draw from the top, and win 4 tricks if the distribution is 3-2.

lead low to the jack. If this holds, run the 9 next. If it loses to the king cash the ace next.

The only time you will ever not get 4 tricks with this line is if its stiff king offside.

You pickup KTxx on your left, and KTxx on your right (even if they duck with KTxx offside when you lead to the jack, when you are about to run the 9 lho will showout so now you'll play the ace and lead up towards your hand).

9 towards the J. Let's hope somebody plays the 10 or even trick them in to covering with an honor. If the 9 wins, well, you have to cash the ace now, if it's Kx or K10 doubleton, you are winner, if not, you will still get 4 tricks eventually.

Perhaps I was not clear.

Suitplay tells to play the 9 "just in case" LHO covers, but if LHO does not cover, play the J anyways.

It does NOT tell to run the 9.
