What relative position is your tag opponent? Tag limped in late-middle, thus wont have a 88 unless all the other limpers limped in before him/her. Against one or two limpers, tag would have likely isloated with the 88 or would have bet a K on the flop (or even isolated PF). What is your table image? As played, I cannot see the tag as beleiving you have a K, and is often bluffing or hoping to win with an 8 and/or 9.

I don't fold this river, in fact, I think I raise.


About playing in BM. Realize that even bad players can pick up on tells; they often have a lot of experience. Read Caro's book on tells.
