Anyone notice this "teaming phenomena"?

[salloch]

I only play BM 3 or 4 times a year, but each time it seems like the 1 2 3 4 seats and the 10 9 8 7 naturally "team" up, and you get an "us" vs "them" vibe going against the other side of the table. It seems like the "teams" will play each other softer, and help each other when one of them is against a player on the other "team".

Is this a well recognized phenomena that the regular BM players see? Or is this all in my head?

Since I don't play enough to know, I'm curious to hear from regular BM players...

Thanks!
