Ok, I spent a while trying to read the game to the end:

Final Result: W+2.5. Black didn't make that sente push, and I think it gave me the little edge I needed. It's a bit complicated, but I think all my next 10 moves are sente. Black can't deviate from the sequence above without losing points. It's a very close game, but I think I can protect those 2.5 points to the end.

The whole thing is a bit complex, but here's why my first two moves are sente:

Well, I may as well put this out here. I don't expect you'll agree with this whole sequence, but just choose the point where I made a mistake and we'll continue from there

. If you do agree, the final result is W+2.5.

I can think of a couple of alternative sequences, but I don't think I find any that would lead to me winning, so I guess I may as well agree.

Thank you for an interesting game, and congratulations on the win.

The game has ended, so there is no need to hide comments any more. I looked, and it seems that you are right, but OTOH white won anyway.

for the beginners who often miss easy endgames:

below sequence is 1.5 point better than what he had in mind.
it is simple but often missed by sdk players.

I think the above move was a mistake for white. In retrospect I wish I had played something like a or b (as susggested by Dusk Eagle) or maybe c. I think this was a bad strategy and put me behind.

This move is pretty obviously a mistake for black, letting me off too easily. Daniel the Smith made a good suggestion for a better sequence:

I think this was also a big mistake for W. I should have just protected my stone with a. In my comments I say "I can't stand the idea of passively defending", but really I think black is helping white to make points, so I should just accept. I was close to evening out before, but now I fall behind again.

This was a big mistake for b. compare to Harleqin's sequence:

After this white gets a huge side and it's enough to be competitive again. I think black followed white around a bit too much in the endgame. Consider this sequence I predicted:

In the actual game black just blocked at 5, but the top is sente. I can't trade that stone on the bottom for the top: I have to block I think. that's quite a few points difference given the sente pushes I get there later. But then, I missed the endgame moves suggested by Magicwand and explo, so probably my endgame also needs work!

Thanks again tj86430 for the fun game, and thanks to everyone who commented.

Likewise, both to you and for comments.

My teacher (Antti Törmänen, EGF 6 dan) will go through the game on our next session (some time next week), and has promised to give some comments in english I can post here.

Magicwand, can't white play like this instead?

I think the correct way is to draw back first, then throw in later. Black's mistake in the game was not to throw in before blocking later.

thanks for getting it reviewed! It seems like we found most of the big things he mentioned, but there were a few good points there I hadn't seen, especially handling the shape on the upper left in the beginning.
