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.
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.
