Suit combo

SP divide the group in 2 lines of play.

 

A - Low to J against small,low to J against Mid (9 ot T). Playing the J after xQKx) against falsecard of QT,Q9.

 

B- low to K against small or Mid. Not Playing the J after xQKx. (therefore playing against AQ). This probably mean that defender should falsecard close to 50% with QT or Q9.

 

If you need 4 tricks A is better if you need 3 B is better and for average A is 4/1000 better (probably a rounding error IMO).

 

West will always play the Q from AQ but for the rest

 

-------1

If West never falsecard...

 

When a small appear declarer should play the K it will win against East stiff Q.

 

when a mid appear declarer play the J and return the K. Even if west is holding AT or A9 it change nothing.

 

This will gain vs Q9 or QT.

 

When the Q appear he will play the K, and return low since AQ is the only case.

 

--------2---------

 

If west always falsecard with Q9,QT but doesnt falsecard with ATx.

 

When a small appear he should play the K it will win against East stiff Q.

 

When a mid appear he should play the K and return the J it will win against AT,A9 and T9.

 

When the Q appear you cover (east should always duck) and return low against AQ by West.

 

 

 

 

------------------------------------------------------------------------

 

If west never falsecard with Q9,QT but always falsecard with ATx but not with Qmx.

 

when a small appear declarer should play the K since Qmx is now more likely than Amx

 

When a mid appear he should play the K since Amx is a lot more likely than Qmx or Qm.

 

This mean that west falsecard with Amx too much he should falscecard with some Qmx too :(

 

Im going to stop here before I bury myself deeper.
