As we seem not to have noticed which small diamond LHO led, the only distibutional information we have at that this point is that RHO has ♦K, so he has one fewer vacant place than LHO. The chance that RHO has ♦J and ♥K is 12/25 * 11/24 = 0.22. The chance that LHO has ♥K but not ♦J is 12/25 * 13/24 = 0.26. Hence the finesse currently has a 4% edge.
That's quite a bit smaller than Frances made it seem, but indeed not Very small. If we had to guess now, clearly we would finesse.
I am relieved that Frances strategy is also to cash a safe number of clubs first. The not so very small edge of 4% could disppear as soon as we see how the clubs split.
