First of all, I agree with Ashtar about the low "offense treshold" of many BM players - yes, Americans but Italians as well. Personally I use to insult my friends...expecially when they do stupid moves...

...well, stupid move..I don't agree with Ashtar on the fact that loop-is-not-your-friend. And I love stall as well! VERY often, the BEST move is the most predictable one, expecially when you are playing with high skilled players, who use to think "naaaa, it's impossible...he wouldn't stall this time, too bad!"
Simply, there's no rule. Play a lot of matches, try to know your frequent enemies, and MAYBE this will help you to "survive"...my most hatred fellows are just crazy ones - you simply CAN'T figure out WHERE they will be next turn..

and above all...who cares? have fun!
