Representing Simultaneous Moves
To represent a simultaneous game in extensive form, we use an information set containing two nodes for Player 2, neither of which P2 can distinguish (because P1's move hasn't been observed).
Perfect Recall
A game satisfies perfect recall if every player remembers their own previous moves and what they knew. Games without perfect recall can have counterintuitive equilibria.
