I didn't know until today that you can copy the hand history (in SharpStats) from Poker Nordica, paste them in the hand history convertor on FTR and it will convert them. After they have been converted they indicate that the hand was played on Cake Poker, which is not a problem. At least for those who want to have them reviewed by other players on forums such as here or GrinderSchool, we now have a way.
