2,4 lil deep: turned broadway-->river pairs board

[rand]

...so villain is an idiot and hes running at
44/22/.75

i gave him a huge range for calling my 3bet, this may be the most 3betting ive ever done pf...plus hes a station

anyway im not so sure about my turn bet size, i was planing to milk him i thought he could have just about anything

then, once we get to the river he pretty much insta pots this...now im thinking he may have gotten tricky with a set, or had 2p2-->boat or ak maybe 89, or air

im leaning towards this being a value bet though based on timing/flow
