Even if they have 88/1010 its still 42/57 so you have really good odds especially if they have any lesser holdings.
were not 42/57 after the turn which is where the question arises, your odds are reflecting the flop not the turn. were about 70/30 underdogs after the turn if he has a set. but in MOST cases you could expect a 3bet of my check raise on the flop if he had had a set.
