I do not like my opponent disconnect

It is not the first time I play with an opponent, who disconnects and I have to leave the game. Why? Did he cheat? I am disapointed...
I have to play with leks-adler and I had to leave after connecting and disconnect and end up killing me my lady

I don't get it. Why did you have to leave the game?

I was angry. Each movement was connected and disconnected. I think something that is not normal. If you are playing you are playing. In the end my lady ate me and I left.

Maybe I'm wrong, but I think I was looking for alternatives off the game board to my plays. I can not prove it. But it is not the first time that happens to me. I know it can be cheating. And then I got angry and I left.

I'm sorry but I'm suspicious already

I am afraid, you are far more a victim of the cheating paranoiacs, than of the cheaters.

I do not sure...

Stay calm
and
Eat ladies.

When an opponent's connection indicator dims it may be because he has switched to another window or application. That may be because he's up to no good, or it may be because while he's waiting for your move he's simply chatting with someone, checking twitter, checking his email, etc. If his moves are not suspiciously strong then you're just hurting yourself by worrying about it.
