Well put, Nemesis. That was pretty much my line of thinking, but I was far less sophisticated.

Turns out the button had K9, for the rivered 2nd boat, and MP1 had, believe it or not, 88. Basically 2 hands in a row where he played an unimproved pocket pair super aggressively. I added him to my buddy list, so that I might follow him table to table forever.

Thanks to all who posted.
