I have three games to share I played earlier today (and one from earlier this weekend).
Conditions were not optimal, meaning it's mostly between blitz and live, with moves never taking over 15 seconds. So actually fairly blitz.
That doesn't mean the games weren't serious attempts. I do feel that blitz is also a valid method of "training" Go, as long as you don't always do it.

Anyhow, what's most interesting for me is that, after slowing down my Go progress immensily, I feel I've really passed the DDK bar for good this time. If you win games against DDK while blitzing (opponent wasn't necessarily blitzing and used his time far wiser than me... Not the issue here), I think it's safe to say my Go instincts are of SDK quality.

I request game reviews in order to have stronger players point out moves that don't belong in the SDK range. Unfortunately, there is hardly anything to say about my reading in these games, as per the blitzing, but it's mostly about: eye for sente, large moves, direction of play...
The games I lost playing like this (against 7kyu, 4kyu...) I have already reviewed with Leela plenty myself and the message there is: non-sente move kills my pace and ruins the game. I post the games I won here, because mistakes are less likier to have been punished.

For practical reasons, I'll split up the games in 3 different threads.

(I am MeesterJonas - my profile for playing in the classroom with the Go club :lol: )

Game 3
This game was my first time every playing with such a large handicap (as white). So the victory for me was real important. 15 kyu is not weak, so winning with 4 stones (and 40 pts difference) is a big thing for me.
I thought a lot about dwyrin's basic series during the game. I feel it helps me focus my games.

If you want to secure your SDK standing, you'll have to start thinking in terms of efficiency and dual-purpose moves.

In the position below, any defensive move from 'a' through 'd' will work against the immediate threat. You played 'a'. That is an adequate move: it defends. But the upper part of the group is stronger than the lower part. In particular, the circled stone should attract your concern.

So 'c' is the best move. It defends against the threat, and covers a weakness against future threats.

Also, now you can play a white stone at 'e', and still walk away with sente:

These little improvements can be the difference between a 10K and a 5K.

Thank you very much, Joaz. That is actually a very good suggestion.
I think this kind of thing is mostly due to my "lack" of experience. Such an elegant way to defend against a white hane, yet I wouldn't consider it. I will try to remember it now, though.

I think my development to SDK has mostly been: diminishing quantity and quality of mistakes. The thing you say is another category, one I'm less familiar with. Good moves, good tesuji... these are things I'd like to learn in the coming months/years :)
