I'm trying to work on my middle game. I've been reading Tesuji and doing all sorts of things to help my middle game.
I played this game against a stronger opponent and I feel I completely lose my grip on the game again during the middle game. Invasions, reductions... I always end up on the wrong side, whether I get invaded or invade myself.
So especially technical pointers on how to improve my middle game are highly appreciated!

Re: Middle Game pointers?
At your level, you will improve more rapidly by improving tactics than by improving strategy. But since you asked about middle game ...
through 
aim at creating a large moyo along the right side. This is a fine middle game plan. Your subsequent play needs to consistently support this plan. You should be happy to see the W invasion at R17, since this allows you to further advance the plan by blocking on the right side, which you did (good).
invasion at Q12 is your first test. This move is probably a W overplay. At least it is very risky. You need to either capture this stone or make substantial profit from an attack. 
is an excellent move to start the attack.
By the way, do you know the status of the W upper right corner group? (B can start a ko to kill.) Keep this in mind during the fight. If W manages to escape, you are likely to have lots of ko threats, and losing the ko becomes small if B no longer has territory below to defend.
is weak, letting W off the hook. You must block and N13 and continue to confine W. The right strategy is to drive W toward your strong position above, using it to attack. The wrong strategy is to use that group to make territory, which is what 
looks like. (If you intended as an indirect attack on W, preparing to play N13 soon, then I withdraw this criticism.)
chickened out for no good reason. Cut at M15, continuing the attack on the large W group. W has no time to save the M16 stone, so you get some immediate profit. After 
, W appears to have weathered the attack with little damage, and the B position above has been pressed low and small.
OK, I can't resist pointing out some tactics. For
, pretend this is a tesuji problem: B to play and capture. (The first move is obvious; it requires a bit of reading to verify that W cannot escape.)

Re: Middle Game pointers?
Thanks, I'll read this carefully but first let me react: I am also looking for tactics, of course. So this can be tesuji for attack, defense, cutting, connecting... Actually I'm looking for "technical" help in the first place. Mostly I have a good idea, but how I do it is usually not the best way to do it.mitsun wrote:At your level, you will improve more rapidly by improving tactics than by improving strategy.

But just focused on the middle game (which was perhaps a silly question, because there was no endgame and in the opening there is only strategy
EDIT:
Useful advice, thank you.
Yes I chickened out a few times, which cost me the game. That's exactly the reason I want to improve my middle game / fighting.
was a move unworthy of any go-player 
I'll look into the top right corner position, because I think it'll come up again!
once again there is no excuse for this lame move. My fighting spirit had deserted me by then and that's fatal in a go game against a strong player.The Tesuji problem: It all starts with D12. As far as I can read, I catch these two stones.
So once again I chickened out without good reason
Thanks for the good pointers! I need to increase my technique for dealing with invasions and attacking and then I think my game will benefit a lot from that

Re: Middle Game pointers?
Hi, Ian,
From my KGS 5 kyu level (with Leela's assistance) :
You did a very good job attacking White's invasion at move 32.
It seems to me that you let complex situations develop, while reading complex situations is not your best strength.
For example, after White 54 in B4, I think you should block at B5, in order to keep the left side safe. This way, the situation is much easier to read.
After White C6, I think that following with Black D6 is easier : white in on the 3rd line and Black on the 4th one. So it is balanced.
According to Leela, you were doing well until move 117, where you ataried from the wrong side. The right move was 117 Q15, with a winning probability of 50 %.

More tactics: at 
you have a better move than s12 that keeps your enclosed stones and the attack on the white group alive (at least as far as I can tell...)

Re: Middle Game pointers?
If you want to get better at the middle game, you have to stop playing moves like 17 ( below) in the opening. You have to be able to imagine White's response at 
and ask yourself, "What next?" After 
(19 in the game), White should have immediately captured at 
. White makes a huge profit in what was originally Black's corner. In addition, it is now inevitable that will turn out to be over-concentrated since "a" and "b" are miai. There are various alternatives for Black in this corner but learning joseki is not the theme of this analysis. The point here is that 17 in the game damages Black's position. Black does know enough to realize that connecting against the atari would be slack (17 becomes a wasted move) but probably there was nothing better.
Later on in the play against the invaders in the upper right, Black can consider driving White in the direction of the lower right. Imagine that Black plays the hane at below and prevents White from pushing through at the top. Black 7 and 9 channel White along the side and Black is going to be able to justify some additional moves that make use of the lower right stones in attacking White.
One more point. On the left side, look at what happens when you answer 
with below. The stone at 2 means that if you capture at 7 (as you did in the game), you have an inefficient shape. You have used five stone to capture 1 when you only need 4. If you are going to capture at 7, you want to do so instead of playing 2. In this case, the ko (if White plays 2) may be hard to fight. Black has a lot at risk along the left side. So playing 2 makes some sense. Then however, we cannot capture at 7. We have to play 4 instead. Imagine that White can successfully connect at 5 (which wouldn't happen in the game). Even then, Black would be better off to cut. It takes some reading but not a lot. The White stones cannot escape. Black becomes strong so White becomes weak. This is the essence of fighting in the middle game.
Okay, ONE MORE "one more point". If White answers below (instead of 117), 
kills.

Re: Middle Game pointers?
Thanks for the helpful comments.
ez4u, those are some very interesting diagrams. Yes I had realized the error of 17 all too soon
Diagrams 2 and 3, I should've been able to see. It was not my best game. On another day I might've played them.
The last diagram is tougher. A difficult L&D situation for me.

Re: Middle Game pointers?
You don't even need to do that. All you need do is note that you have sente, and that you got to make the first hane. There is blood in the water.ez4u wrote:If you want to get better at the middle game, you have to stop playing moves like 17 (
So just based on that, you keep the pressure on him. You make a double hane.
Footnote: Okay, technically you didn't hane. But you two arrived a the same shape as if you had haned at the head of two stones.
Consider it like this:
Try to develop a feel for the flow of the game. When you see moves 1 through 6, move 7 will seem natural.
Listen to your stones. Your stone at R4 is screaming for backup.
You may have to swap moves around a bit - especially with the haphazard disregard for temperature that one sees in kyu games.

, does anyone have access to Leela's evals, and its next move ?
(a) gets you "hane head of 2; hane foot of 2" -- perhaps not an unreasonable candidate to consider.
is very strange indeed -- some misunderstanding of something. You need to fix it. -

Re: Middle Game pointers?
Hi Ed,
This is a fairly recent version of Leela Zero, right before ELF. This is not at super high playouts, but LZ seems to think that the pro move is the best by a safe margin. It also seems to think that (a) is a terrible move, dropping the winrate down to ~25%.
More playouts could change these percentages of course.

Re: Middle Game pointers?
Two suggestions to think about:
1) Make multipurpose moves. That is to say make moves with two or more threats or with more than one follow-up. Splitting moves and leaning attacks fit this description.
2) Consider playing useful forcing moves before taking gote. In particular, when in a situation of having to make life, play forcing moves before the final, gote, life-making moves.
