jardaholy Posted February 19, 2021 Report Share Posted February 19, 2021 There are daylong boards, you really asked yourselves “Does it make sense to play bridge like that?”. [hv=pc=n&s=s63h6432dat5cq732&e=sk2hak97d742cakj4&d=s&v=0&b=11&a=ppp1cp1sp2np3sp4sppp]266|200[/hv] The bidding was fairly normal and so was also the first lead, HQ. The declarer took it with the ace and played small spade to the ten, holding the trick,continuing with small club from the hand and finessing the queen. How would you continue? Since I was the lucky possessor of the queen, I had to decide, whether to cash ace of diamond immediately or to play small diamond making the robot to carry out its thousands of simulations and guess the position in diamonds, if necessary. However, there may be no need of guess and even if it is, the robots are, in my experience, very successful in that (may be more, one would expect looking at the odds). So, I finally cashed diamond ace and played ten, which took the trick, the declarer following the diamond suit with 3 and 8, my partner with 6 and 9. What now? There was no clear indication of the distribution of the diamonds around the table, but I was sure, that the only continuation making sense are diamonds. So, I played the last diamond and the board was over. [hv=pc=n&s=s63h6432dat5cq732&w=saqjt54hjt85d83c8&n=s987hqdkqj96ct965&e=sk2hak97d742cakj4&d=s&v=0&b=11&a=ppp1cp1sp2np3sp4sppp]399|300[/hv] There was small flesh of idea inmy mind that the very first lead could be singleton, but I could not imagine how the declarer with complete six tricks in spades, four tricks in hearts and two tricks in clubs, i.e. enough tricks for small slam, could risk being limited to nine tricks, if the finesse did not work. It could be nice story about cruel punishment of a real beginner just understanding the principle of finesse and finessing everything everywhere, but it is absolute mystery for me, how advanced computer program can play such a way. At least, there is no problem to run the trumps before the finesse, if the robot finds some justification for making it. So, I missed giving ruff to my partner, finishing the board with nice 50% result. Quote Link to comment Share on other sites More sharing options...
nullve Posted February 20, 2021 Report Share Posted February 20, 2021 What kind of daylong tournament was this? Zenith Daylong Reward (MP) maybe? Quote Link to comment Share on other sites More sharing options...
pescetom Posted February 20, 2021 Report Share Posted February 20, 2021 It was already clear from the initial pass that West was having a bad day. Quote Link to comment Share on other sites More sharing options...
Douglas43 Posted February 20, 2021 Report Share Posted February 20, 2021 It was already clear from the initial pass that West was having a bad day. I think the robots do not open a weak two with 4 cards in the other major? Quote Link to comment Share on other sites More sharing options...

nullve Posted February 20, 2021 Report Share Posted February 20, 2021 Yes, it was Zenith MP.Then West was an advanced robot. Can you post the Handviewer link here? I want to replay the hand against basic robots, but then i need to know exactly how the play went at your table. Quote Link to comment Share on other sites More sharing options...
jardaholy Posted February 20, 2021 Author Report Share Posted February 20, 2021 Fair enough, if that is so. Well, that reminds me one real board from my colletion "One hundred boards with robots", played in IMP daylong 26.10.2020.My hand was: [hv=pc=n&s=s97hkjt5d9843cak7&d=w&v=0&b=8&a=ppp]133|200[/hv] I am a conservative bidder so that I decided to pass for several reasons. The first one was that I do did have spade suit so that my opponents could find spade partscore contract leading to good result for them and bad for me. The second reason was that I had opened several 11 HPC boards recently and my partner had pushed me to 2NT contract, or, in one case, even 3NT contract with bad result for me. The true was, I had had bad experience with passing 11HPC daylong MP hands, because it had usually led to 30% result, which is pretty bad, if you need at least 60% to score some reasonable number of BBO points (more than 0,01 point or something like that), but this was IMP board so that I did not expect big loss and would have been surprised with a loss bigger than, let us say, 2 IMPs. So, I passed and could see that my decision was badly wrong, because the complete board was: [hv=pc=n&s=s97hkjt5d9843cak7&w=sq8hq987632dajc85&n=sakjt653hd65cj963&e=s42ha4dkqt72cqt42&d=w&v=0&b=8&a=pppp]399|300[/hv] All players, who opened the bidding, bid and made 4 spades. It should be pointed out that not only my partner, but also west passed the hand, which would definitely qualify for preventive opening.
