1eyedjack Posted December 12, 2012 Report Share Posted December 12, 2012 Are we permitted to know the trick target? Or perhaps you think it irrelevant? Quote Link to comment Share on other sites More sharing options...
PhilKing Posted December 12, 2012 Report Share Posted December 12, 2012 I've no idea what the problem is, but I guess the answer is "run the jack". If West covers with the queen, consider ducking, but at that stage I would probably ask what contract I was in, what my hand is, and what the bidding was.

benlessard Posted December 12, 2012 Author Report Share Posted December 12, 2012 Aim for the best average of tricks. Side question does having the 876 change anything ? Quote Link to comment Share on other sites More sharing options...

SteveMoe Posted December 12, 2012 Report Share Posted December 12, 2012 Suit Play says the following (unadjusted for open spaces): Line A: Small to K (follow-ups depend on what falls)Line B: Small to 8 (follow ups depend on what falls)..........A...........B4.......3.39%.......3.39%3......62.17%......58.78%2......95.22%.....100.00%E.......2.6078......2.6217 Tricks MP best is B. If we don't have the 876 then we must have the 765 - K72 - J6543.Line A low from both hands E=2.4978Line B low to K E= 2.4696 so A is BestThere is a Line C that is worse - you can check it out. Yes the spots have a bigger impact on the expected yield (E) than the choice between the best lines for each card set! Suggest you go to Suit Play and get yourself a copy. Best analytics program I've seen. Quote Link to comment Share on other sites More sharing options...
PhilKing Posted December 13, 2012 Report Share Posted December 13, 2012 There is a Line C that is worse - you can check it out. Lead the jack? I wasn't serious lol, but if East is likely to be short we pin stiff T or 9 and West may cover erroneously (in a vacuum it loses to stiff A,Q,T or 9 in West). And as for line B, we are only playing the 8 if the 5 appears. And that is only because, on simulation world, the suit could be 5-0. Context is everything.

SteveMoe Posted December 13, 2012 Report Share Posted December 13, 2012 None of the 3 lines involves running the J. Line A leads low toward dummy and ducking round 1 when LHO plays low. Then low toward the K.Line C leads low similarly, but repeats the low/duck play at trick 2 (ostensibly playing for Ax with RHO). Quote Link to comment Share on other sites More sharing options...
benlessard Posted December 13, 2012 Author Report Share Posted December 13, 2012 I agree with suitplay :) In short Ducking and low to K is slightly better at mp than low to K and low to J because QT9x--A+Qx--AT9 are slightly more frequent than xx-AQx However if you hold 8+7 you can cover a LHO 9 or 10 at trick 1 because you can finesse against the other 9 or 10 on the way back. Looking at the numbers i see the difference is a lot smaller than I would have tought. Also if you need 3 tricks low to K and low to J is best.
