apologise in advance for quiality

MP reg (tag)
BTN big rec; he is pretty splashy: a)capable from wide stackoffs 2)stationy 3)agressive enough and bluffing bunch of different hands by that I mean he can sertainly bet 56 there as a bluff

On the flop I decided to check for reasons that dont have too much value and dont want to increase pot OOP and face ugly situations
On the turn I dont like x/c w/o spade and with many river cards which make me hate my life
On the river I have decision to make, no good blockers whatsover but considering his image ..
