Many players have questioned the tournament staff on who can call time if a player is taking too long in a hand. Almost every hand is a long, drawn out ordeal and it seems to be annoying some players that would like to see more hands to play. The tournament staff just made an announcement to inform the players that anyone at the table can call the clock during a hand that they believe has gone on for too long. The staff also mentioned that the players should play a little faster.
At any rate, we've gotten down to under 50 players. We are getting closer to the money, so this could very well be the reason why play is slowing so much.
