is there currently a way to see how many times an ace has fallen on the river to the winner of the hand? Or any particular card on any street for that matter. It would be interesting to see the percentages of each street, not helpful perhaps, but will statisfy one of my curiosities at Pokerstars.

Yes, you would want to do this with a custom report and you would want to filter on id_river ; see the custom reports guide for general basics.

Specifically you want id_river % 13 = 0 .

This returns 0, 13, 26, and 39, the id numbers for the 4 different aces. (I think they're clubs, diamonds, hearts, and spades in that order, but I'm not 100% on that).
