I play black. The game went well for me until the middle where I let my group get cut.
Comments and questions are in sgf

For I can't think of a world where I don't play your alternative move on that board or some kind of capping move to try and make white live on the side without giving up my 3-4 stone. Touching your opponent's stone, as in game, is just helping them here. Just instinct, too tired to read it out very far.

7: I like this move, and the reasoning behind it.

15: As you observed, you have some weaknesses.
A good rule of thumb: most attacks do not succeed in killing. Most ofthe time you will get your profit in something other than killing your opponent's group. Many times - and this is one of them - just making your opponent protect himself with a small gote move is your profit.
I would play P10 here.

17: P10 is better. If he tries to cut, you have the ladder.

19: If you were at P10, you could hane here.

23: Good shape move.

25: Nooooooo! You can't quit here. You have a weakness at R16.
You can play R16, or O16, or maybe O15, but you cannot tenuki.

26: You should love this invasion. It is an overplay. He is way too close to your wall. Your wall is overly strong because you played Q9 instead of P10. But now he lets you use that wall. You should be overjoyed to see this move.

27: Push him against the wall.

Let's take a break from individual moves and talk about opening theory for a second. The idea behind the Chinese is to enclose a large area, so that you opponent feels compelled to invade ( If he doesn't invade, sooner or later you may turn it into a big moyo ). When he invades, you attack, and when he runs, you make territory while chasing.

Look at your game with that idea in mind.

It is working in the upper right ( if you don't quit too soon )

You can make it work in the lower right too. Playing R4 at move 27 is great. It is the hammer that pounds him into the anvil at R9/Q9/S9.

45: This is aji keshi. Leave it.

57: Probably too close to his wall. Haneing on the other side looks better.

63: If you are going to play this line, it can only work if you play H3.

A second time you leave a corner unfinished. This is a bad habit. ( It is not clear to me if you die if he were to play B1. )

87: Good shape move.

It is late here. That is all for now.

I think that move 101 was quite bad, but White had failed to punish it.
This is one of the most easy way.

Thanks, very helpful comments

Mr. Heisenberg, I rapidly played through three of your games. Nice software and display.

You seem to make a lot of forcing moves that could be saved for ko fights, e.g., nozuki. You play too close or on the inside of your opponents influence, then you add to the group before sacrificing it to gain outside influence. This seems to be your M.O. Play moves that serve your strategy, to reach your goal. You seem to change strategies too often because you failed to read and were foiled.

Read two books on direction of play. Play at the widest place. Play the urgent move before the big move. Don't get into fighting so early. Don't be jealous of your opponent's territory. Instead, play a big point.
