NL50 87s

I was doubting to x/c turn OR bet turn and bluffbet blank river. I think x/c is more standard though.
I took some time and wondered if a tripple barrel bluff made sense here on a blank river to fold out hands that could call flop and turn like Q10s (3combos) J10s (3combos) KQ (12combos) 88 (3combos) JJ (6combos)
