easy suit combo I didn´t know

Dont you just cash the ace? pick up all 2-2 and half of 3-1?

 

Running the ten picks up all 2-2 except KQ offside, but loses to stiff honour onside. It gains against HHx onside. However, those two are exactly equal. Running the ten will pick up KQxx onside, but that is less than KQ offside I think.

There appear to be a number of reasonable lines in the suit, which I'll consider in turn. There are 2^4 = 16 possible layouts.

 

1) Cashing the ace wins on 10/16 layouts (all 2-2, stiff honour on your left or right)

 

2) Low to the jack (then cashing the A if it loses to an honour with LHO) wins on 10/16 layouts (all 2-2, stiff honour on right, KQx with RHO)

 

3) Running the 10 then playing low to the J (could cash A on 2nd round but this trades two 3-1 breaks for one 2-2 break so is not right) wins on 10/16 layouts (all 2-2 except KQ on right, 4-0 onside, KQx on right, Hxx on right)

 

4) Playing a low card off dummy and covering whatever LHO plays wins on 11/16 layouts (4-0 onside, KQ9 or Hxx onside, stiff H on your right, all 2-2 except HH on your left)

 

So you should play a low one off the dunny and cover RHO's card, repeating this on the second round (for the same reason that it's right to play low to J rather than cash A on the 2nd round in line 2)

A) - KQ92 (1 case)

B) 2 KQ9 (1 case)

C) 9 KQ2 (1 case)

D) KQ 92 (1 case)

E) H H92 (2 cases)

F) H92 H (2 cases)

 

And all other cases are irrelevant. You'll pick up all other 2-2 breaks by leading low from dummy twice or by cashing the A and nothing you can do about KQx(x) offside.

 

Cashing the ace loses to A, B, and C (3 cases)

Running the 10 planning to finesse again loses to D and F (3 cases)

Running the 10 planning to cash the A loses to E and F (4 cases)

Leading low to the J loses to A and E (3 cases)

Leading low to hand and covering whatever RHO plays loses to C and D (2 cases)

 

Last one is a winner? Unless case D being a 2-2 break makes cashing the A or low to the J better enough to account for the extra case given up. (Think those two are the same). I always forget how that works.

I am fairly sure that in a perfect world it is right to start by taking a deep finesse, but in the real world it matters whether or not you think your RHO is capable of playing the 9 from 9x or H9x.

A long time ago, I held 9x in a similar situation and played the nine. My clever false card put the contract down. Declarer complemented me and more or less apologized for thinking I wouldn't be able to find the falsecard.

 

Well, I wasn't. I had merely signaled a doubleton to partner. ;)

What Fred said is what I was thinking, you´ve got to play 9 from H9x and 9x to avoid being hooked off your KQ9 and protect partner´s stiff KQ

 

The best play of the suit depends on the info opponents know since playing the 9 from H9x is normally costly if we have 5 card suit.

Doesn´t count because you posted it on the wrong forum :P

But you responded anyway (reply #42). :P

 

Of course, the real gem of that thread is reply #26 - possibly the only time Frances has ever written a 3-letter post.
