My raise comment addresses the "everyone limps" aspect of the hand, which I think devalues his 88 with 5 other players in the pot. Also, a raise PF lowering the number of opponents in the hand in question increases his chance of winning it, and might give him a better idea of where he stands.

Montimus, you didn't mention the stakes, stacks, MTT tourney vs SNG vs Ring game, these are all factors as well. Oh, and the outcome of the hand?
