His turn check raise didnt make any sense, so my plan was to float with my draw planning to bluff most rivers unimproved. I've been experimenting with smaller river bets sizes with decent success. Then I made a friend and encouraged him to call

nice moment you 2 shared there
you can make it 3x pre with all your range this deep
not a bad flop to cb
Q high fd might be ok to call turn c/r but I'd fold lower spades
his turn c/r does make sense for value, 55,44,AT,A5,A4 can all play this way, why would he lead turn?
would like to see a bigger river bet, not a huge polarizing one, but 2/3p-3/4p or so gets rid of more of his stuff and you look more like you're going for value than that 40% bet
