Blind vs. Blind semibluff checkraise

[Lmn55d]

Ok, this guy is unknown. My first question is about the flop checkraise/turn bet. Do you guys think a typical player folds the turn enough to make this combo profitible? I figured there was a good chance I had some pair outs in addition to the flush outs, so it wouldn't need to work that often. The river bet is second question. Pointless? I thought there was a good chance he had a bigger ace and might dump.
