Umm...Spidey - If a player leads a Wizard, there is not considered to be a suit, right? So the fact that train played a diamond doesn't mean that everyone else must play a diamond, right? But with a Jester, the next non-Jester played does determine suit...
I'm I remembering this correctly?
It just seems odd to me that with the overbid situation, everyone is ditching trump....
Anyway, assuming the plays are all correct, I'm leading 10 of Diamonds
