You can do it (says me who is heading down the 1300's at present)
Advantage = Virus activation

I agree w/you 100% !!! I never have a connection issue when I'm hanging pieces left and right. But let me trap a queen or have a mate in 3 and the app starts crashing or I lose connection (just to the game mind you, Internet is still working just fine). It's very suspect to say the least.

Here's the thread I posted on this same issue last week ...

Absolutely!!! I'm glad I'm not the only who notices this phenomena. Really cost me a lot of games and points.
Yup once again I lose connection the minute I gain an advantage by winning a piece. No issues when the match was equal for 1st 15 moves. It always seems when a major advantage is attained the connection craps out. It's as if a magic button is pressed to activate a loss by abandonment. A nice 18 point swing. 9 I should have gained but lost 9. It's happened many times before once an advantage is gained. I guess 1400 is a pipe dream for me under these conditions.
