Little backround: This is right near the end of the first hour. I'd been running over the table playing a laggy style and hadn't shown a premium hand down yet (hadn't even had one, but not the point). I'd been in a few pots with the original minraiser and thought he was remotely decent for a $4.40 but the other three hadn't shown any skill yet. Original minraiser has raised my BB quite a few times and we've played a lot of hands together.

Looking for discussion on this move.
