kenrexford Posted October 1, 2011 Report Share Posted October 1, 2011 Suppose that you are in a spade contract, trumps having been pulled with one trump remaining in Dummy. Suppose also that control and transportation are not a problem. Suppose, further, that in diamonds no one can have a stiff or void. With A-10 in Dummy, you have in hand either: Q-J-x-x-x orQ-J-9-x-x What is the significance of the 9? I have a reason. I just thought this might be a fun bridge problem. Curious to see if anyone spots what I think significant here. Quote Link to comment Share on other sites More sharing options...

Curious to see if anyone spots what I think significant here. The significance is that I can lead the Q from the QJ9xx suit even when I need 4 diamond tricks, trying to make lefty guess whether I'm trying a Chinese finesse, whereas (all things being equal), I cannot try that with the other suit combination unless I can afford to ruff a diamond with dummy's last trump to set up the suit if they are 4-2.

kenrexford Posted October 1, 2011 Author Report Share Posted October 1, 2011 Here's what I was thinking: If an assumption play means that RHO needs the diamond King, for example, you have the alternative line of small to the Ace and back the 10. If RHO plays you for Q9xx(x), he will assume that his duck will induce a duck from you as well, you catering to Kx left or KJxx left (and a ruffing finesse). Without the 9, RHO might have K9x and thus not be as likely to duck smoothly, as he will not as easily expect you with Q8xxx to run a line catering to Kx left or KJxx-9x as the split. Technically, the duck still might be right with K9x, but it is a lot harder to spot. So, having the 9 seems to be a good thing if you need that line coming in.
