Not unless you are assured to have high enough participation going in. Otherwise, keep out. Nick :-)

I don't know anything about that club league. I suggest you message the league's SA, @iSpaceChess, to let you know about expected team strength (e.g., the expected number of players to join each match). Or if you joined that club, you could copy and paste the information from that club's forum/news here.
