In game 4 at move 100 you wrote, "Black is a bit behind, I think. White has a lot of points." But I think Black would still be in the game if you had played down at L3.

Could very well be. I feel in this game, my endgame was very bad in that white got most of the big points (including L3 area).
I think I made mistakes earlier, but I agree black probably had a chance at this point.
I really should figure out how to play endgame one of these days. It seems like "low hanging fruit", but when I sit down to study, I can't help but do life and death problems, so I never really learn endgame.

Based on the game I just played, I wondered what the biggest point is at this point in the game:
11 - looking up the joseki was interesting. The first joseki given in Takao's is just the stylish H6, black E3. Later, white has d3 d4 d2 to get a ko for the corner or other follow ups.
26 - Seemed a bit eager to me.
34 - I was tempted to wrap around the outside instead, though that seems weak territorially. What do you think?
36 & 40 - both surely better at q10
I'll look more tomorrow.

1.) There are cutting points around the marked areas.
2.) The approach at R6 is great for black's development.
3.) The thick wall at G3 is powerful and makes it difficult for white to develop.
SoDesuNe: I do like this because:
1.) The approach at R6 can easily be pincered while taking the corner and neglecting a Black framework on the right (e.g. 1-3).
2.) Black's wall around G3 has no potential because White got Sente to defend the corner at O3 while simultanously neglecting Black's thickness.
3.) The cutting points in the marked area are for now irrelevant, in my opinion. The shape itself has potential to make something out of the left side, though.]))

In the lower left, let's look at what happened. Below is one standard continuation when White extends at . IMHO this is what White should have done in the game.
I would probably have played above at below to make the best of a bad situation. Black gets in and before returning to but White shuts off the side in better shape.
In the actual game, White answered Black's cut at E12 with F11, allowing Black to cleanly capture the D12 stone. So in effect, Black 35 ( in the diagram) was a threat to connect two living groups along the second line. White definitely should not have answered it. The alternative of Q10 on the right instead of B7 on the left is an excellent move.
One alternative that strikes my eye would be the hanging connection at E13. It would expand White's wall and loosely link it to the top left corner. If we imagine that Black plays on the right and White responds on the top as in the game, the play at the top would be much more powerful with the back door on the left side shut by a White stone on E13.
answer to your above question on Q10........ it is big but doesnt have any purpose. fuseki is more than throwing a stone in an open space. your move have to have purpose to it. I would have played J4. it is big and build your influence and take away opponent's growth. If black take that side then you have top side that is open... miai. sorry for being so cold on comment. i feel that you have reached the level where you should think about such. for weaker players playing that move is fine but for you i expect higher standard.

If white plays j4 isn't black happy to occupy the right?

I thought the right looked a lot bigger than the bottom too...
