Sooo in speed games or, casual games for that matter, a players moves can effect your game. Good or bad they can effect you both ways. When a player makes a terrible move and you tell them they did. This is grounds for a negative if they so choose. I have seen players tell me "I play for fun and do not take it serious." While that is all great, and it is what most of us do does not mean you should point out bad moves? Oh you become the bad guy for "whining" or "abusive in chat" if you get mad when a player suicides into you or makes a bad play. I am sorry, but I am going to tell a player if they have made a bad move or not. Speed or casual games, makes no difference. I thought all players played to win? Maybe I am wrong and some just do not give a rats ass if they win or lose. Anyhow debate away and flame me if you must.
End of Rant.
