OGS game lost to Herman Hiddema. I think I can be proud that I lost only by komi against 4dan. As Herman pointed after a game - better yose could even get a win for black because his better center position after middlegame. However I think there was still higher probability for white to get the edge.
Thanks Herman for the game!
#127 probably a losing move.

After 24 or so, doesn't fighting spirit insist that you take advantage of white's omitted move in the bottom left? This was ignored for some time before white fixed, but to my eyes it seems like free sente moves for black before the fighting started on the top side.

Sure, but at what moment exactly? That is a question
I had no clear vision of what I could get with playing there because I was not so sure if it would be a sente. I thought he could ignore any move I play there and just enlarge a moyo on the upper side. I thought it was a bad idea to give him great central potential so I played a reduction there first, then attacked right side with impetus I got.
It was big and I was looking at it all the time, I just didn't get a chance because all other places were still hot.

Changed title once again.
Ok, today I played almost 3 hours game. One hour of basic time for each player and one minute byo. And we both almost lost on time...
It was no komi game and black managed to survive by 5 points (New Zealand rules). White had a chance to turn a game a few time but he made few simple mistakes.
There are a few comments in this game but they are in... Polish

So if you want to see some strange looking words or you are brave enough you can try to read/translate them.

I guess I'm thinking immediately, before responding in the top left. Either white responds and black builds some potential on the bottom in sente, or white tenukis and there's a trade. I think if white doesn't respond immediately, white outright dies in the corner, which is a fine trade for the two stones at the top left, from black's perspective.
Alternatively, maybe after move 26 black can play on the top side and treat attaching and C10 or so as miai?

Thank you for drilling this, it forced me to look over some pro games.

Next White played 'a' and black 'b'.
Of course there are a lot more than these two games.
I was not too familiar with this opening but now when it took my attention I will be more confident dealing with it. Thanks!
Time for study.

I've never actually seen games like that before, but I think everyone has seen games where black and white complete the normal joseki on both sides. It stands to reason that if white deviates, black has to deviate too, so it's just a question of where and how. The examples you provided certainly look quite playable (as you would expect, being pro games).

I play this opening, with facing 3-4 point (mukai komoku), quite often as white.
Usually, I would just reply on the bottom left, and then black would play the same again in the top left and finish with a move halfway, i.e:

However, in the game the right side has already been played a lot, and is mostly finished. Given the low position black has in the lower right, I figured it would be better to focus on the top left first, as I don't mind much if black builds influence along the bottom.
I think, therefore, that black should play the corners in the other order. If you connect in the top left first, I would respond there, and then you could have played the lower left next to get the same result as in the above diagram, but with the order

Thanks Herman, I found it quite strange that I was only thinking about bottom corner and never even thought about reversing order

. It's interesting that I haven't thought about priority of corners in this situation and I can only hope to avoid mistakes like that in my future games.
I think I need to challenge you again to learn something more. Beware

Next game played with 1 hour time for each player. This time I was white and lost by 7.
During a game we discussed how much time we should have to play with no significant pressure at yose, and to feel satisfaction about quality of our play. Turned out that 3 hours would be optimal for each of us.
Pro players from the past were saying that quick games are important.... while playing 20 hours matches by themself. So what is a quick but in the same time a good game? 1 hour per player? 3 hours? If all is about a subjective quality of game then how much time is needed to feel that you are not playing some kind of ancient shooter or other arcade game but the beautiful game of go?

It looks like my go development will stop for some time because I finally got a job after a long time of unemployment. I will spend more than hour in train everyday, so maybe then could be a good time to do some tsumego or study pro game.
Oh well, back to OGS, need to complete my 15 games there as soon as possible.
Merry Christmas!
