I'm beginning to lean towards the idea that this game gets upset if we're logged in too long.
My reasoning comes from experiences over the last couple days. While at work, I like to play a quick game vs AI5 while waiting for various work activities to complete (IT professional and alot of my time is taken by "hurry up and wait" items). I usually run 99% win vs AI5 unless I just get a horrible draw. However, over the last couple days, I've noticed a trend that as the day goes on and I've played more games. My draws get increasingly bad. I've lost 4 times in a row to AI5 2 days in a row now, later in the day after having been logged in for a while and having easily won many more than these losses. Of course the losses come from completely screwed draws...
Any thoughts? Is it perhaps developed to get people to leave after a bit and re-log back in? Maybe an attempt to represent a banner ad or something?
Thanks,
