Square Fuseki ▪ Square Opening

That’s my spin of the whole idea, but since it originated from this thread, I post the results of my ventures here, to give credit where credit is due. :slight_smile:

The concept is that since this is not immediately “squarish” the opponent doesn’t catch up early that a deliberate shape is being made and so far noone has interrupted the building of the parellelogram.

Also, I thought that since it is odd and not as clearly symmetric as a square, it will be more stable than a square or, at least, more intimidating. So far, noone yet has tried to invade it.

That game is also going well… I almost fumbled it, but at the moment it is heading for a very rare victory against a dan player. I am so excited, I cannot wait for the next moves in DGS, I kepp pressing f5 every ten minutes hehehe :smiley:

And the stones of the fuseki? Surprisingly ideally placed! :smiley:

The game is finished. I won (W+9) against a 1 dan player! :slight_smile:

If anyone would like to add comments or a review I uploaded the sgf file:

I also got “squared” in one of the other games, but I was already in place to hit the vital point:

Though I was very tempted to play at M6 instead of M5…

On a related note, I realized a way to make 4x4 square symmetrical:

If the opponent wants to invade it, for example at tengen, you can make good shape and turn the invading stones into a heavy weak group. The purpose of the square formation is to be strong in the area, you don’t need to fully enclose the territory inside of it:

Though AI is telling me Black has a better result after these moves, so maybe White should consider playing somewhere else instead of responding. All I know is I like the shape, and I would prefer to have this kind of center fighting instead of corner joseki and reading corner-based life-and-death.

2 is ok but 4 is really bad, forcing white to break your own shape. Better to tenuki, or at least play 6 directly if you want to connect your square without hurting the top left stone (but hane outside probably better).

You’re right, this looks much better for White:

but I can see White has a small weakness here too:

Black gets this peep in sente which can cause trouble if ignored.

So the best move is to tenuki after playing a sente move against Black’s invasion and sacrifice the remaining corner of the 4x4 square:

I mostly have comments for black. Above all it is to learn the double hane joseki.

I just noticed you took all 4 corners as White :thinking:… Great job squire!

Is this also considered a square fuseki?

I was black by the way.

IIRC I added that example to SL when I was studying that shape, it having come up in one of my OGS games. :slight_smile:

Examples from amateur play


Uberdude I once made 2 throwing star shapes in the same game next to each other! I’m not claiming they were the best moves, but I thought they were an elegant way to make shape for my group. (1+3+squares is one, squares+circles is other.) I uploaded the game to EGD: [ext] http://www.europeangodatabase.eu/EGD/See_Sgf.php?Sgf=1433714710286067G091228A7&Pin1=14337147&Pin2=10286067

In games against kyu you can just continue to build something.
There is always hope that they would just let you build it.

The challenges that I issued on DGS against higher ranked opponents with the express goal to play the variation of the square fuseki that I like, are winding down.

I won one of the games against a 1 dan (see previous post).

Resigned another one against a 3 dan:

Resigned another one against a 3 dan:

And I am currently about to resign another one against a 1 dan. This one was very close (it was so close it could have even be down to a couple of points), but I just did a life and death error and it is now futile. That was so close!

The only one that is ongoing is this game against a 5 dan, which is going ok, I guess, but I am increasingly worried that I’ll find a way to mess it up. :sweat_smile:

The GameGoSeries channel (which is imho the best Go YT channel that I currently know of) seems to have played against @shamisen who used the beginning of the parallelogram fuseki (minus one move) against GameGoSeries. It seems that the game was interesting and that led him to make it into a video:

Alas it is for subscribers only, so I do not have access to it. :confused:

But I did locate the game:

Shamisen won! Well done! :slight_smile:

I am seriously considering subscribing just to watch that review… :sweat_smile:

In my own correspondence game, things are progressing slowly and I think that I am messing things up slowly…

Yeah I was happy when I had the chance to play against my favorite Go content creator, win or lose! And it’s unfortunate you all can’t see the video for free – he basically uses my opening to explain that the game of Go is a very “free” game as in allowing a lot of freedom. I paid $2 and then immediately cancelled the membership just to see the video, it was personally worth supporting him considering I got great value out of 50+ of his videos in the past.

technically true since a square is a parallelogram, but it’s supposed to be a rotated square. it’s 3/4 of a mini black hole opening

You look fine to me if komi is 6.5, there’s still one or two big fights left to decide who wins. I’m not sure if I’m allowed to say any more than that since the game is still ongoing.

Unfortunately I won by timeout. :confused:

At least the score calculator says that I am still ahead at this point, so that’s some redeeming quality.
