rhm Posted February 17, 2014 Report Share Posted February 17, 2014 Against best defense you probably need LHO to have the diamond ace doubleton or singleton.Does this mean you should play on diamonds?No you lack the hand entries to establish diamonds. Even if you overtake the spade in hand at trick one and shoot back a diamond LHO can go in and shoot back a heart. So diamonds can not be established against best defense. Play on clubs instead. Let dummy win the first spade and continue spades.If this holds, play clubs from the top and hope they are good for four tricks, in which case I do not see how the defense can deprive you from 2 spades, 4 clubs, a diamond and two heart tricks. The defense could establish two diamond tricks if LHO has more than 2 diamonds because in this case the hand gets squeezed on the run of the clubs Playing on hearts early is dangerous, since the defense could come to 3 aces, a heart and a club trick.

bluecalm Posted February 17, 2014 Report Share Posted February 17, 2014 I am tempted to try another spade hoping they duck and then play club to the T.If they take it I have 4clubs + 2 spades and only need 3 tricks in red suits which I will get as I have two stoppers in hearts.If they take a spade and switch to heart then I take in hand and play T of clubs.I have 3spades, 2hearts so they can't really afford to take it and if they duck I am trying D to the Q.It seems to me that this line works very often. I run a double dummy simulation with assumptions that W has 12+hcp, 4spades, 3-4 hearts and As. Here are the results at trick two: Cards, winning, best:Qs 603 997Kh 7 37h 408 6176h 408 6172h 407 614Qd 342 6195d 333 446Ac 531 803Kc 528 802Jc 16 4049c 16 4047c 19 407 Even double dummy playing one top club isn't the best and I think my line is the reason.

Zelandakh Posted February 17, 2014 Report Share Posted February 17, 2014 My line would have been ♠T, ♥Q (losing), ♠Q, ♥J, ♣J. I am not claiming this is better than Rainer's (obviously), just interested how it does (since I am too lazy to enter in a DD solver) and how much worse it is.

I am not claiming this is better than Rainer's (obviously), just interested how it does (since I am too lazy to enter in a DD solver) and how much worse it is. W/o commenting on the overall approach what is the purpose behind leading the club J ratherthan starting clubs from the top. Playing clubs from the top will get you 4 clubs anytime theQ or 8 drop singleton or doubleton and gasp 5 clubs when the Q8 are doubleton. Leading the Jfirst appears to be a pessimistic approach to the game with no practical benefits. Quote Link to comment Share on other sites More sharing options...

Leading the Jfirst appears to be a pessimistic approach to the game with no practical benefits. Leading the J does nothing that cashing AK doesn't and loses to Q and Qx, small to the 10 is better in that it establishes 4 tricks against a 5-2 if the 10 is taken.

Zelandakh Posted February 18, 2014 Report Share Posted February 18, 2014 It loses against Q or Qx with East and gains against Qxx with West, no? My feeling (no maths) was that the latter would be more common. Oh I see the confusion - the lead was in hand so ♣T led and overtaken by the jack.

I am not claiming this is better than Rainer's (obviously), just interested how it does (since I am too lazy to enter in a DD solver) and how much worse it is.This line looses when East has ♣Qxxx. Once you start on hearts the defense will continue hearts, establishing a heart trick in addition to a club trick and 3 aces. I mentioned this danger previously. It loses against Q or Qx with East and gains against Qxx with West, no? My feeling (no maths) was that the latter would be more common. Oh I see it, the lead was in hand so ♣T led and overtaken by the jack.No! You can afford to lose a club trick if West has Qxx, as long as you lose only 3 aces in addition. This is possible if West has no more than 2 diamonds. Assuming from the bidding and opening lead that West has all the aces and 4-4 in the majors, the hand can essentially be made if either 1) West holds no more than 2 diamonds, where you can afford to lose a club trick or2) West has 3 or more diamonds but the club queen drops and you do not lose a club trick unnecessarily.

Zelandakh Posted February 18, 2014 Report Share Posted February 18, 2014 OK, I see the issue. Luckily I do not play against any Easts who would find this heart switch from their (now singleton) ten into the suit we led twice raher than play back their partner's suit (also led twice). If this is the only problem then I am happy enough. :unsure: Usually I have missed something much more serious on these problems, since I always struggled in this format (even more so than f2f).

lamford Posted February 18, 2014 Report Share Posted February 18, 2014 (edited) I have not read any of the other posts (I will do so after, of course), so apologies if I repeat any points made. I don't think it can be made if West is Axxx ATxx none Qxxxx, so I will play him to be Axxx ATxx x Qxxx, and play a heart to the jack at trick two. If West ducks, I will play a club to the jack, cash just one more high club, and now play a low diamond from the Qx to the king, followed by reverting to a major. I must not play the low spade, however, as West can fly ace, cash the ace of hearts, and exit with a spade. I need the low spade as a stepping stone to dummy. So, play king of spades, which West wins, cashes the ace of hearts, and exits with a spade. Now I cash the other high spade and throw West in with a spade. If West wins the first heart and exits with a heart, I win in hand, finesse the jack of clubs, cash one high club (again necessary), and play a diamond to the king (it does not help East to rise) and play a high spade from South as before. It would not matter in these lines if West were Axxx ATxx A Qxxx, as I would still make. I don't think I can make it when West is Axxx ATxx A xxxx unless I duck a diamond completely early on, which would be a big view. I see on the actual layout West is 4-4-3-2. Playing a heart to the queen at trick two still works fine. If it holds, I will finesse the jack of clubs, cash the ace, and then it is easy as the queen drops. And if East has [cl Qxxxx there was no winning line anyway. If West wins the heart and exits with a heart, a club to the jack and cash a high club works as before.

HighLow21 Posted February 20, 2014 Report Share Posted February 20, 2014 Win the spade in dummy, heart to the Q♥, and if it wins, lead the 10♣ and overtake with J♣. If this fails, wonderful. If not, I establish clubs and simultaneously unblock and establish my majors. I could go down on a diamond lead from lefty, but this line makes it more likely that if diamonds are going to be broached early, it will be by righty.
