Poker Face: Flotsam is a quest from Chapter 1 in The Witcher 2: Assassins of Kings.
When Geralt was staying in Vizima, he was less known among the gamblers as a witcher and more as a consummate dice poker player. His fame spread across all of Temeria and there were bound to be people in Flotsam who would recognize him as a gaming partner. Geralt was immediately invited for a game with two local players. He also learned about a third - the local champion, a man who wouldn't play with just anyone.
After defeating first three local players, Geralt was told to play dice with Einar Gausel. The first three local players are Casmir, Bendeck and Zindrab. Casmir, Bendeck, and Zindrab can be found at a table located at the inn in Flotsam. Zindrab can only be challenged by Geralt when he defeats Casmir and Bendeck. Then you will be directed to challenge Einar Gausel.
- Completing this quest before beginning Troll Trouble will remove a possible option in the plot. The reason being is that eventually you will have to roll dice against Sendler, who will offer you the head of the she-troll if you beat him in a game of dice; only if you have begun the troll trouble while having defeated some dice players before him.
