gszes Posted May 30, 2012 Report Share Posted May 30, 2012 Ususal opponents or not low from dummy (intending to play the 9) allows usto pick up 15 of 16 potential trump positions thoughtwo of those 15 (rho K8 or K5) will require us to guess well when we continue the suit. We for sure lose out only to stiff J with lho and we will probably lose out toJx with lho because it's tough to give rho credit for being able to duck with Kx. The net yield of thisplay is at worst 13 of 16. As shown below the worstthis LOP can yield >= the best of the other choices. playing the A and toward the Q loses to lhoKJ8KJ5KJ85 net yield at beat 13 of 16 starting with Q intending to take double finesseloses to rhoKJ8KJ5KJ85net yield at best 13 of 16 leading low towards the T intending to double finesseloses to tho KJKJ8KJ5voidnet yield at best 12 of 16.

Benoit35 Posted May 30, 2012 Author Report Share Posted May 30, 2012 How about starting with the 9 from hand, intending to cover with the ace to read LHO's mind a bit? Strictly speaking, this is inferior - only 12 for 16, losing against Lefty's KJ8, KJ5, KJ85 or void. However, with KJx(x) LHO needs to smoothly play low under the 9... any hesitation on his part would mark him with something, and we could change our mind and let the 9 slide. Not against the rules AFAIK, but is it ethical? Quote Link to comment Share on other sites More sharing options...
Phil Posted May 30, 2012 Report Share Posted May 30, 2012 However, with KJx(x) LHO needs to smoothly play low under the 9... any hesitation on his part would mark him with something, and we could change our mind and let the 9 slide. LHO splitting with KJx would be a blunder (imagine stiff Q in pard's). OTOH, when RHO has Kx, in practice its very tough for him to duck in tempo unless youre playing against robots.

But yes, dummy to the 9 and counting milliseconds before RHO's card falls seems like the way to go. Quote Link to comment Share on other sites More sharing options...
phil_20686 Posted May 30, 2012 Report Share Posted May 30, 2012 A)low to the ten, then run the Q picks up all except KJ KJx off side = 13/16 holdings. B)low to the 9 then low to the ten loses only to J-Kxx Jx Kx = 13/16 holdings. But its technically worse since 2-2 breaks are more likely. C)Ace and low to the Q loses only to KJxx Kjx with lho = 13/16 holdings. Generally, B is preferred as its not so easy to duck from Kx. Against genius card playing robots A and C are better. If there is any inkling on the bidding about who has three hearts, you should choose between A and C though. Quote Link to comment Share on other sites More sharing options...

C > A by apprx %2 A loses %19.21, KJ offside( % 6.78) + KJx offside, happens 2 times with total of (%12.43) = % 19.21 ---> A wins %80.79C loses %17.21 ,KJxx offside (% 4.78) +KJx offside, happens 2 times with total of (% 12.43) = %17.21 ----> C wins %82.79 Quote Link to comment Share on other sites More sharing options...
Zelandakh Posted May 31, 2012 Report Share Posted May 31, 2012 Bridgehands suit combos says running the Q then low to the ace is the optimal way for 4 tricks. It seems logical that it be included in the comparison. Quote Link to comment Share on other sites More sharing options...
Statto Posted May 31, 2012 Report Share Posted May 31, 2012 Cash ♥A. This is a book position as they say in chess. Small to ♥A is psychologically better, but you might not be bothered to do that if you don't have an entry without risking a ruff. Fails when KJx(x) is offside, but you need a suspicion of that to play for it. Quote Link to comment Share on other sites More sharing options...

It seems logical that it be included in the comparison. They are wrong. Running the Q is the optimal way for 5 tricks, not 4. Starting with A is the max % to make 4 tricks Running the Q loses to ( i am assuming you will go with double finesse) KJ offside OR K stiff offside if you are planning to cash A in 2nd roundKJx offsideKJxx offside Starting A loses to KJx offsideKJxx offside Quote Link to comment Share on other sites More sharing options...
