Stop Being a Dick Rule
Any agreement made between two parties is expected to be upheld by both parties even if not explicitly approved by the host. Examples: agreeing to no timer, agreeing to playing Little Cup instead of BW OU, etc. Violators of this rule are subject to a sportsmanship infraction at the very least, possibly more. Exceptions will only be granted through direct appeals to one of the hosts.
Andrew's Amendment
A player has the right to violate any previous agreement pertaining to the state of the timer should his/her opponent take more than five minutes on a single move or should the match's duration have exceeded thirty minutes. This would mean activating the timer on PS, or waiting another five minutes and then claiming the win on PO. The timer should be activated on the same turn.
Please just don't agree to any bullshit timer rules and play with the timer OR don't abuse no timer clause so you can avoid this stupidly complicated rule.
Snunch's Proposition
Any player found to be lying about availability will be subject to a suspension of a week or more, with additional punishment at the hosts' discretion.
