Lead J toward length, intending to finesse. Win if covered, then small to 7/8. 5 tricks 79.1% of time. Win 6 some 3.4% of the time. Gives up 2 to to K109xx on side and 3 to 0 - 5 offside. Gives up 2 to all x - xxxx.

The jack is right because it picks up KT9x and KTxx/K9xx onside, losing to stiff king in either hand.

I assume the mistake is that it is recommended to cash the ace, which would be correct if it was AQ5432 opp J6

An interesting combination I had never thought about before. Messing around with Suitplay confirms that this suit is handled differently with the 8 and 7, with only the 8, and without the 8.

I routinely think of 8s as "x"es and expect them to make no difference to how I play a suit, except for sometimes giving me a bonus trick when a singleton 9 or T falls. But there seem to be a lot of combinations where it matters. Anything that gets me out of that complacency is a good thing. Just tonight on BBO I saw Qxx opposite T97xx, where the right play is different from Qxx opposite T9xxx.

For 1 loser, the 6 is significant here.

I do not get it.
I have the second edition of Reese on Play (1978) and it gives

AQ8xx opposite Jxxx (low to the queen for 5 tricks, lead the jack for 4 tricks)
AQxxxx opposite Jx (ace first)
A9xxxx opposite Jx (low to the jack)

I can not find your combination at all.
Where is the mistake?

By the way, I am aware of many mistakes in Reese books. It is still one of my favorite authors.

I have found a first edition called "Master Play In Contract Bridge" from 1960 in my library.
This mistake has been corrected by Terence himself in the second edition.

Is this the one where you lead the T to pick up stiff 9 on either side (overtaking if 9 appears on your right) as well as stiff Q or J on your right? And RHO grosvenors you by playing the 9 from QJ9x under the T then laughs at you?

The book I have is Reese on Play, Better Bridge Now.

Chess & Bridge edition 2001 reprinted in 2006

Like Justin said he suggest bagging the A to pick up stiff K on both side.

Like most people found the correct answer is running the J first followed by low to 9/8 (if JKA on round 1).

If you believe that LHO is 2 times more likely to be stiff than East leading low to Q & planning to run the J (if the Q win and a stiff 9/T fall) also make sense, it win against

Ktxx---9
K9xx---T
K------xxxx

but lose against

KT9x----x

since
K---xxxx is one case and
KT9x--x is 2 cases

14 must have twice the odds of a 41 break for playing low to Q to make sense.

If he breaks tempo by a fraction I'm going to be the one laughing, but yes it is.
