to access the hand history, you need to click the hand number at the top right of the table. for some odd reason the partypoker replayer does not show the hole cards, however they ARE included in the hh. The ability to see someone's hole cards after a showdown: if you get to showdown and someone mucks their hand, you have the right and ability to see it. People seem to be confusing a few things here. There is an option in the stacking section called display cards when folded but not sure if this is correct option. I see it on my Hold em manager but it doesn't display on the table or in the replay.
On party poker is there a option for it to show the opponents hole cards when you go to showdown/all in.
