Thanks Arend, I am convinced now that I need to remake how things look like, a friend made a suggestion with mostly green as background and I will do it if I ever feel like it. Do you have any other suggestion?

I am stilll thinking about board 17, that was the only hand I made, I included it yesterday when I found my father's math was wrong (see kgr's explanation)

Board 25:

Alternative line: Play for Kx onside.

I think this is _extremely_ close. Kx and Kxx are almost equally likely (depends a bit on whether we are supposed to infer s.t.h about the heart length), so it roughly depends on whether playing for the (squeeze or ♣T dropping) is over 50%.

Below is an output from Pavlicek's Dual suit break analyzer. I excluded voids (partly to save some work, partly because no lightner double), and didn't specify vacant spaces for simplicity (should do that once for Kx and once for Kxx obviously). In the "Plan A" column, I entered the number of combinations for which the squeeze would work for the given distribution.

According to this calculation (which is obviously a bit imprecise), the squeeze works 48% of the time.

So I should add ♦10 to the equation to make the squeeze better

was really easy too.

First one I actually got wrong was #35, played for the wrong squeeze. Then #36 stumped me, a lot harder than I thought.

A double squeeze that i have played like hibryde retaining comucating in clubs too instead of twin entry lonely in diamonds (ruffing a club)(Lovera)
