interesting + complicated 20/40 hand, and is this collusion ?

"if all 3 players were normally rational tag/passive, 100% i'll check the turn."

When they check to me on a board of A- [img]/images/graemlins/club.gif[/img] [img]/images/graemlins/club.gif[/img] [img]/images/graemlins/club.gif[/img] and I have A [img]/images/graemlins/club.gif[/img] with a kicker above all the board cards, I'll bet here roughly 100% of the time.

Who exactly do you think were colluding? SB and BB? Why wouldn't BB put in a raise at any time during the hand?
