A quick review follows. Aside from tactics, I really think you are playing a lot of forcing moves where you are hoping that you opponent will not see the threat and will play elsewhere. But these are in places where I don't think that even at your level you can expect your opponent to misread. Janice Kim calls this out as one of her seven dangers, "irrationality." There is a flurry of such moves from 42 to 50, for example. (Actually, a couple of those moves would be total gote against an even stronger opponent, but since he responded, we'll call them sente. Your luck on your opponent answering everywhere will run out soon, though.
) The problem with this is that if your opponent answers correctly, the resulting exchange is bad for you. You can't expect your opponent, especially a stronger one, to misread things you can read easily. Please, leave these moves unplayed. You can use your dead stones as ko threats later, or get truly useful forcing moves as the game develops. If you settle a lost position too early, you lose all those options.

(;B[jc]BL[1790.2]C[White 1 is a 3rd-line stone if viewed from the top side, but a 4th-line stone if you look at it from the left side. So the left side is more developable.
An approach near D15 is what is called a 2nd-class move by Yilun Yang 7p in "Fundamental Principles of Go." (A first class move being a move in an empty corner.)
Black 2 he would classify as a third-class move, since it is a midpoint play on a side where only one side can develop.

Not only are the black stones in the corner surrounded, but they are also short of liberties. What's worse, black has a broken shape with the marked stones. You have to try not to allow this shape in your games (unless it's your opponent's stones being broken, then it's great.
