I would check it on the river. You aren't getting any value by betting middle pair here, he will call you with hands that have you beat like any K or AT (his calling in the BB usually means his kicker with T is higher than 7, but you'll split the pot with 2 pair K kicker ), and fold hands that you have beat, busted flush draws, and I can't see him calling a river bet with something like 55-88, you've played this hand exactly like you have a K: You know he can check raise you if you make a continuation bet, so you check with 2 over cards (he thinks this since you raised preflop)then when a K pops up you fire on the turn and river? Looks to me like you hit one of your overcards. I wouldn't call here with 55-88.
