Smart HUD - What will I see when I open another player's Smart HUD display?

The view will change depending on which game you select. The main differences are as follows.

Cash Games - 
In cash games, the Smart HUD Box shows a particular player’s recent VPIP, PFR, ATS, 3BET stats and the number of hands played, along with their personal history. Stats are based on all hands played during the session.
You will also see a record of your best and worst hands vs this player.

All in or fold -
The Smart HUD in AoF will show three additional items: player's total jackpot winnings, their latest jackpot hands, and their playing hand distribution.

Spin & Gold -
Spin & Gold Smart HUD will show total winnings, average finishing place, biggest multiplier, biggest prize, and the current Spin & Gold Challenge (if applicable)

Tournaments (including satellites) - 
Tournament Smart HUD contains a player's total tournament earnings and their last 5 tournament results.
