Post subject:  Playing larger moves

Hello,

In my playing, I mainly play small moves like theses :

or

I'm award that playing too many of these small moves is inefficent... but I have difficulties playing larger move, by fear of being cut...
So I play some kind of "too strong structures" which "often" lives but without making enough points for me to win the game.

I don't know where to start to improve this... are there topics that may help me ? thx

Hi oca, it is very difficult to talk about this in the abstract or in general.

For example, you can start by studying this basic 2-space jump, on the 3rd line.
Homework 1: Can W cut this jump ?

Homework 2: study this joseki. Notice the shapes you asked about:
the keima [ :w1: - :w3: ], the keima [ :b2: - :b4: ], the 2-space jump [ :b2: - :b6: ] --

I went through a phase where I played small connected moves. The problem is that larger moves aren't necessarily connected, furthermore there are more tesuji involved with larger moves, since there are more ways to cut, so it becomes difficult to pick the appropriate move, since there are so many possible outcomes.

Post subject:  Re: Playing larger moves

There's the classic advice of doing go problems. That can teach you tesuji involved in cutting or connecting your stones when they're farther apart. If you can read that your stones are safe for the moment, you can be more confident playing the larger jumps.

Go Teaching Ladder is a great resource for seeing amateur games with comments by stronger players. See how players above your rank use small and large jumps, when it works and when it fails.

Finally, it might be helpful to think about it this way: If you play very safely, your opponent gets ahead just playing normal moves. If you play moderately aggressively, you've created opportunities for your opponent to cut and kill your groups. But, you're making him find strong moves to pull off the attack. You're giving him the opportunity to overplay and fall behind. It's better for your opponent to kill your stones, but really have to work for the kills, then for him to stroll easily to a small win.

Thanks EdLee, here is my second try...
for :b6: I will set a ladder...
and for :b8:, force white to crawl to get a big wall in return.
is that correct ?

No.

Every move you make must have a purpose. (If it has more than one purpose, even better.)

What are you trying to do here ? What is the original question ?
( What does the ladder have to do with the original question ? )

If B plays :b6: as you did above, what is W's correct :w7: ?

Yes I agree, wrong direction... back to assuming a larger move and connecting the two stones to get a base.

I think :w3: and :w5: just died this way, but I was first a bit worried about :w7: at "a"
that's why I play :b6: there in my first try.

but now I think I can handle it. may be something like that (small moves again but ok in that situation I suppose...)

Correct. By "weak" you mean "dead" in this case, because :w9: kills :bc: -- this is why :b6: above is wrong.
:b6: has nothing to do with the original question: can W cut the 2-space jump ?

The :w7: atari above is the only move for W, not the second-line turn in your original variation:

If you are worried about :w7: at (a), then the correct thing to do is READ it out.

Not OK. What is the purpose of :w3: ?

( The :w3: - :b4: exchange is good for B, bad for W. It makes a bad shape for W. )

After you've seen the above variations so far, you can now see that
your original :w3: wedge is a bad move -- bad instinct on your part -- W would not play there.

:w3: and :w5: was the only moves I found to save both the marked stone and :w1: menaced by a ladder at (a).
I suppose both white stones are now saved as I think black is forced to play (b)

[edit]full wrong, can't save both groupes after black at (b)...[edit]

But maybe I'm just too focused on saving stones...

Post subject:  Re: Playing larger moves

The key thing you should do is count liberties. With the correct block for 6 white's two cutting stones only have 2 liberties and all of yours have more. So if your stones get in danger you can capture the white cutting stones to connect all your stones together. So for 4 above it might be even better to laugh in white's face and tenuki, though your 4 is a nice thick move which reduces opportunities for white to get some useful forcing moves in exchange for his dead stones.

Thanks for the lesson, I think I've got it, I will now try the same on the 4th just to see the difference
I suppose I should try to build a kind of vocabulary of moves (I mean not just find their name on internet but really experience them) and start walking before running

I really understand better :b6: and I'm now confident with it, it can't be cut.
For white, is :w3: at (a) a valid option too ? oh... but then black would enter at 3-3 and play the 3-3 invasion joseki instead right ?

Black can play the same joseki if white played :w3: at A. The difference is that at some point white will have to do something about the open skirt by making an extension or otherwise fixing it, making it somewhat gote, though it can be tenukied. In exchange, white has more strength in the center.

So close! You were doing great until the final move for B. In this problem, B is trying to connect some stones. Those stones count as being connected if B captures any potential W cutting stones. Other stones are irrelevant and do not need to be saved. Focus your attention on the main problem ....
