Life In 19x19

I thought about move 35 to be played on M14 or Q14 but I thought G13 would be better to build a big mojo.
I thought Q14 isn't a big benefit for me or for white and M14 I wasn't sure if white can life and if I still can build the mojo with G13.

65 Why I should generaly avoid empty triangles?

For move 35: your move is certainly big but

1) You shouldn't think that your moyo is entirely your territory. White could probably live inside your moyo with moves like C16.

2) If your opponent has a weak group, it is almost always better to harass it in order to get "free moves". Only when your opponent is not in danger anymore, you can tenuki and take a big point elsewhere.

For move 65: in this situation, the empty triangle is slow (like nobi vs. tobi), jumping helps you advance faster inside your opponent's moyo.


Concerning your last three games: the computer is still too passive at this level, the games lack invasions and close-range fighting, so you are not yet practicing all go skills. A couple of remarks on game 6, though:

1) At move 37, you can play at T4 directly, this is almost sente. But if you throw-in with T7, then move 39 at T4 is not sente anymore (if you take the two stones, White can take back one stone).

2) is gote, White doesn't need to connect after the atari. There are probably bigger moves elsewhere.

3) at H14 looks better.

4) Move 117 is small, and not sente.

5) Move 119: what is that move good for?

6) Move 121: same remark.

@jlt

Yes that's all correct.
Thx for teaching me.

What are my biggest mistakes and what should I improve?

Game 7



Game 8



Game 9

You are going to save yourself a great deal of time if you stop pussyfooting around when increasing the strength of the bot.

EVEN if you were trying to find out at what level it could play you evenly (and we have explained why that not such a good idea) you would find that point a LOT faster by trying to bracket that level.

For example, if the bot still way too weak, set it up 8k. If that's too strong, down 4k. if that too weak, up 2k (or if still too strong, down 4k, etc.

PS -- I strongly question the supposed strengths of that bot. If THAT is what you are going by, ignore it.

For game 9, between moves 96 and 130, both players forgot to count liberties.

White must play at A5 or B5 to capture Black, otherwise Black can atari at A3.

Yes, indeed. The 7 kyu bot in game 9 is way too weak for you. Try the 3 kyu bot next time.

If you are going to play bots even, do what humans do. Play against a bot that can beat you at least half the time. Maybe it would be good if it beats you ⅔ of the time. Then play it until you beat it twice in a row, once as Black, once as White, and then up it one rank.

Good luck!

I haven't played since a very long time, so this is something like a warm up from 15k to the top .
These games were a big fun and it's easier for me to analyse a game and fix some mistakes instead of playing a very hard game and have ten times more mistakes to fix in the same time.

Another game to analyse
The opening was bad and I also blundered in the middlegame.

Game 10

Game 11
What should I improve?

In the last game, was a good sente move to furhter strengthen your double wall and give Black a cramped position, which he got for not playing the atari in the joseki.

But then 16 and 18 are just confirming Black's life while adding no extra points. In effect, these are wasted kothreats.
20 is worse: Black' doesn't even have to respond. It's close to a pass move.
22 is again like 16 and 18: after that, Black is not just alive, the group is impossible to capture even if Black passes.

I haven't checked the rest of the game as there's enough learning material here:

1) don't play moves that don't accomplish anything else than that the opponent must answer
2) don't play moves that don't accomplush anything and the opponent doesn't have to answer at all

Cheers!

Isn't White the bot? White 12 should just cut with atari and capture the Black corner, no? black has misplayed here but is playing against too weak an opponent to learn better.

My advice, stop playing this silly bot and play people. The silliness is contagious.

Or play a less silly bot. As near as I can tell you are trying to use bots in a way that we tell you they should not be used.

Until it is a mmtter of the high level neural net bots or perhaps high level MCTS bots you should NOT try to use bots supposedly at your own level to play even games against. Use bots set about 3 stones higher than you are and take a three stone handicap. Now they will not do the silliness typical of your level, so you will be able to learn from them.

At your level, there are no bots suitable for you to play even games against.

OK. Then my first advice is: tell us who you are

I was black as you can see under the board.
White was CrazyStone DeepLearning (level 5 = 5 Kyu) running on iPad Pro 12.9-inch.
