[Trivial]

if i did check this river it would be due to some gut interpretation of the timing detail mentioned which i find is often significant with these types (it typically suggests that he has improved but may be still concerned about your hand), however against a 80/5 i feel that shoving has to be correct in general since there are just so many atrocious hands in his range. sure, QK is there, but so are K6-KJ. we just can't worry about one specific hand when there is this much value to be obtained from the vast majority of his holdings.
