'Believing that keeping players seated at the table improves tournament efficiency, the membership expanded some “player present” rules, the most controversial of which is likely to be a change to Rule No. 29, which now says players must be within reach of their chair before the first card, not the last card, is dealt or the hand is mucked. Rule No. 30 now mandates players to remain at their seat for the duration of the hand or face a possible penalty.'
These 2 will probably generate the most turmoil for TDs. Personally I like these changes as I think it will speed play restarting leading to a few more hands dealt per level and less disruption during play.
