KurtGodel Posted May 3, 2015 Report Share Posted May 3, 2015 After a questionable, auction you wind up in 6♥. The 9♣ is led, you try the queen from dummy and this fetches the king and your ace.

rhm Posted May 3, 2015 Report Share Posted May 3, 2015 Your only losers are in trumps. So you intend to play 3 rounds of trumps to the king and if LHO follows low on the first heart, back to the ten, winning when hearts are 3-3 or LHO ♥9x. If LHO plays the ♥9, ♥J or ♥Q you finesse the 8 on the way back and can also make if LHO has ♥QJ, Q9 or J9 or singleton trump and RHO a suitable distribution. But the play diverges depending on whether East has two or more clubs.Best to assume East has three or more clubs. If LHO shows out on the second trump play 2 further rounds of clubs. If both follow, ruff a spade and then play East for 2♠=5♥=3♦=3♣ or 3♠=5♥=2♦=3clubs, by trying to cash the king of spades first.If LHO shows out on the third club, ruff a spade cash you fourth club, play diamond to dummy and then the king of spades to discard a diamond or overruff if RHO ruffs, then further diamonds. If LHO played the ♥J or ♥Q from ♥J9 or ♥Q9 you will have to decide whether LHO has done so from a tripleton or doubleton trump. The latter case is more probable, in which case you need to try a trump reduction play by trumping a spade and then playing side winners ending in dummy. You win the return again play two further rounds of clubs first to find out whether RHO has a fourth club. If yes, ruff a spade, cash your club, two diamonds and the king of spades. If no, discard your fourth club on the king of spades, ruff a spade and 3 rounds of diamonds ending in dummy. Rainer Herrmann Quote Link to comment Share on other sites More sharing options...

A trump-coup seems to depend on LHO holding at most 5 cards in the round suits. Quote Link to comment Share on other sites More sharing options...

It costs if LHO can give RHO a ruff (e.g. LHO has 5♣s). if you intend to play a 3rd round of ♥ anyway, then it costs if LHO has ♥Q9, or ♥J9, when you can no longer take advantage of the trump-coup recovery.

gnasher Posted May 4, 2015 Report Share Posted May 4, 2015 What we would actually do. I think part of the element is deciding when someone falsecards from J9 et cetera...The main thing to do is assume that they haven't falsecarded and play accordingly. If LHO plays an honour, play him for HH or H by finessing the 8. If LHO plays the 9, play him for H9 by playing the ace.If you go down against some normal layout like LHO having Qxxx Q9 xxx 98xx or Qxxx QJ xxx 98xx when you could have made it by doing the obvious, are you really going to tell your teammates that you were playing for LHO to have falsecarded? 1 Quote Link to comment Share on other sites More sharing options...
PhantomSac Posted May 4, 2015 Report Share Posted May 4, 2015 What we would actually do. I think part of the element is deciding when someone falsecards from J9 et cetera... Well, no one plays the Q from Q9 doubleton imo. J9 is a more plausbile falsecard but to date no one has done that vs me. So as you might guess vs the 9 I cater to H9 but vs an honor play I don't.

So as you might guess vs the 9 I cater to H9 but vs an honor play I don't.Yeah, to some extent that's why I posted this (and why I said in the OP - does it matter which honour?). I can't imagine anyone dropping the Q from Q9, that would be ridiculous. I thought it would be interesting how people thought about this situation. The rest of the hand was if no high card falls you should finesse the 8 and play for a trump coup with H9xx onside. On the actual hand it did not matter, as trumps were 3-3 and my drunken bidding (and the fact I thought P would have 3 hearts) paid off.

Nevertheless if LHO plays the 9 it could be singleton and your chances are not that bad making the contract even then, but not if you play the ace on the next round.If you finesse and it losses you are not down yet either.So I am not sure that the ace (the simple line) is best.

Aardv Posted May 5, 2015 Report Share Posted May 5, 2015 Against anyone who knows and remembers Rosenberg's rule - always play the nine unless you must - 9 from 9x is an automatic false card here, so you should finesse on the second round. However, that's a small subset of the bridge-playing population. Quote Link to comment Share on other sites More sharing options...
nige1 Posted May 5, 2015 Report Share Posted May 5, 2015 The main thing to do is assume that they haven't falsecarded and play accordingly.If LHO plays an honour, play him for HH or H by finessing the 8. If LHO plays the 9, play him for H9 by playing the ace. A simple alternative is to play ♥KAT. Gnasher's line: Gains when LHO has a singleton ♥quack and you can accomplish an unlikely trump-coup. Loses when LHO has made a strange false-card from ♥Q9 or ♥J9 (As phantomsac points out) orRHO has a singleton ♣ and LHO was dealt doubleton ♥QJ or tripleton ♥QJx (and has made a more routine false-card). Admittedly, in the second losing case, LHO's ♣9 would be an unusual lead from a 5-card suit (reinforcing Gnasher's argument). But, if RHO holds 5 ♥s, it's obvious that dummy is short of entries for a trump coup. Unless RHO is short in ♣, would he masochistically sacrifice ♣K at trick 1? Is either line demonstrably superior? Or should you just follow your instincts? Quote Link to comment Share on other sites More sharing options...
