Opponent was kind of a weird aggro reg like out of the last 5 situations he check/raised twice.

This board is a board that is good to bluff against weak straightforward regs so when I got checkraised here, his valuerange being so limited I called and played a turn.

Turn is a Q which I can credibly rep but he bets again. The standard line would be to fold but I went out of line and called.
I thought he was out of line too.

Unfortunately he bets again on the river. I don't have great blockers for bluffraising and I'm not sure anymore if he is bluffing or valuebetting so I simply folded... but I believe this riverbet could still be a bluff. The thing is that since I called turn he has to think that I my range consists of a lot of Qx (which it does) and I'm never folding a Qx so it's more likely to be a valuebet OTR no?
