Here is a chart of euchre probabilities

[Dlan]

I was looking through some old euchre files from years back and came across this chart. I' did not create it nor do I know who did. (If it is yours and you want it removed, just ask)

I think that came from me. But easily produced, for 2 trumps but for all the various holdings, 1, 2, 3, 4 etc. Same for Aces or Just the Right.
