ncohen Posted January 21, 2019 Report Share Posted January 21, 2019 10874 QJ2104 Kq73K32 A1084K976 Q3 MP lead: club 5. auctionN E S WP 1D 1H xP 1N (all pass) On this hand, I was proud of using reasoning about GIB's defense to overcome my lack of concentration. N won the club A and returned a heart -- low J low. Then, ht A and another club. I attacked spades. At a critical part of the hand, after S took his 2nd spade trick (with me not noticing the fall of the S9 from N), he exited with the S5. I won the 10 in W this position: 8-- KqK32 A108xK9 --- I hadn't notice the fall of the 9, but figured that GIB probably wouldn't have returned a spade to make a finesse easy. Also, there was nothing to lose by playing the S 8, since the other suits were under control. So, I played it, discarding a diamond, and it captured W's 6 for an overtrick.

smerriman Posted January 22, 2019 Report Share Posted January 22, 2019 I can't quite follow the story. If you lead the Q of spades at trick 5, lose the K and A of spades and get a spade exit by South, you still have the jack and ten left to win the next two tricks.

ahydra Posted January 22, 2019 Report Share Posted January 22, 2019 Please use the hand diagram tool (spade icon on right of editor toolbar). GiB doesn't take into account human-type inferences like this - it uses double-dummy simulations and as such will often do silly things because it "knows" that the declarer will always get a guess right. ahydra 2 Quote Link to comment Share on other sites More sharing options...

But, if there's a chance GIB doesn't know I have a 3rd spade, then the spade return can give up a trick, since I'd be unable to finesse. So, there's a slight inference that the S 8 is good.

zenbiddist Posted January 23, 2019 Report Share Posted January 23, 2019 It takes extra mental effort to try and work out what's going on without a diagram, so I made one for you: [hv=pc=n&w=st874ht4dk32ck976&e=sqj2hkq73dat84cq3&d=n&v=0&b=1&a=p1d1hdp1nppp]266|200[/hv] I'm still trying to piece together what happened. Trick 1: Club to North's ace2: Heart ducked to South's jack3: ♥A4: Club won in East5: Declarer knocks out a top spade6: Sounds like North won and exited the ♠9, and you played high from Hx in your hand? Or South cashed two top spades, and you unblocked?7: South exits a third round of spades, dummy's ♠T winning Perhaps you could find the hand for us here, and post the handviewer link: https://www.bridgebase.com/myhands/index.php?&from_login=1 Quote Link to comment Share on other sites More sharing options...
GrahamJson Posted January 23, 2019 Report Share Posted January 23, 2019 Hmm. If you fail to notice the fall of the nine of spades, which is after all a critical card, I’m not sure that you can call any subsequent reasoning “expert”. Quote Link to comment Share on other sites More sharing options...
