The orange and blue sections of the Amazon room are completely full of casino staff, and the sound of chips rattling on the felt brings on memories of World Series past. We have just crept into Level 2, where the blinds are 50/100. The number on the board shows that 865 players have turned up for this opening day so far, with registration still open for another half hour. Each player began the day with 3,000 tournament chips, and the field has been whittled down to 783 players remaining, as the "Seat Open!" calls are coming fast all over the room.
