So, I had an opportunity to try to play a more "enterprising" fuseki, and I think my moves were sharper this time around. I then chose to make an early cut and the early middle game went badly. I think my opponent and I then traded mistakes -- my poor shape and direction of play versus his slow moves -- and I managed to squeeze out a 3 point victory.

The good news is that I seem to be playing even with the sandbaggers at my current level. This guy should have given me a several stones based on his rank history. Ah, IGS...

I'd also be very interested to know about moves 47-49 in the following diagram. Cutting the white stones seems like a good strategic move, but was it too early?

Hi BG,

:b11: Maybe consider kicking first, then Q11...
Direct pincer allows W R16 attach options.

:b13: Consider R9.

:b15: R17 big. ( You missed the extension on :b13:. )

Instead of ( :b11: :b13: :b15: :b17: ) 4 boxy stones near Q10, I prefer:
- :b11: kicks, then :b13: Q11 pincer ( 1 stone ~Q10; other 2 elsewhere ) ;
-- or, after missing the kick --
- ( :b11:, and :b13: @ R9 ), ( 2 stones ~Q10; other 2 elsewhere ) ;

( Notice the inefficiency of :b11: :b13: :b15: :b17:. )

(I renumbered and added :w50:.)
My concern with the push and cut is that White might atari at :w50: and throw away the four stones to build a wall.

But after :w46: White is very unlikely to do that, since it pretty much amounts to giving up one play. So psychologically this seem like the perfect time to push and cut. ;)

Edit: Objectively, Black has a bigger worry than the sacrifice, I guess.

White can play :w50:, threatening to cut the Black corner off from the left side, for instance with the clamp at "a". Then after Black responds, :w52: captures :b49: in a net.

This illustrates one reason that "b" was better than :bc:.

There are things to like in this game - double approaches and such. It's good to experiment with stuff like this to see how it works out.

:b17: feels like too much investment in that formation. One of the 3-3 points to take away White's base would be the natural attacking move.

At :b33: :

You could consider the :b1: - :w2: combination here, after which White is narrow. You still have the aji of :b3: later, threatening to connect to either side.

:b57: may be the wrong time to tenuki.

At :b63: the answer isn't to move more slowly. Just play a one-space jump at H11.

:b67: is self-destructive. C19 comes to mind. :b69: is a clear mistake even locally, much too inefficient a connection. Consider E8 or G9 if you are worried about cuts.

At :b79:, you're building a fairly narrow area. What are you expecting from this wall you want to build? I suspect the 3-3 point is bigger than the center moves. Once you sacrifice three stones it's not even clear the whole operation gained you anything.

:b99: makes that shape again. Together with 101 you've gained maybe six to eight points from two moves? Connecting in the bottom right is larger because it involves life & death.
