More simply stated: Never peep.

The shoulder hit press at 4-4 must indeed be accepted, even often welcomed as locally speaking it is good for white (the shoulder-hit should be considered a special purpose approach against the 3-3 only for situations where moyos are important, I'm sure this has been mentioned by me and others on other threads before). But there is no reason you must accept being pressed down to the 2nd line by that move 5, which (unless there is a large amount of support nearby) looks like a pretty bad overplay and should be punished by pushing and cutting. If your mindset when faced with that move is on "defending" then you have already lost: it should be on "attacking".

I intentionally edited out the word punish, to give it a more calm sense, but yeah.

I'll try to remember to think more often about my stones as free targets.

My idea was to peep both cuts and cut where b doesn't defend. Now I see that my stone just gives a free move for b to fix one of the sides.

This looks like the best response since if black gets a chance to fix weaknesses he black becomes dangerous. Black then has the option to threaten 3 with a, b or c, and white can run out with either b or c and gets a group in the middle.

I am not sure whether a or b is better for white. I guess vengeance is messy.

I think black is in an inferior position after these, but the fighting is messy, any suggestions?
I am starting to see that getting a live group in a corner and and a relatively secure group in the center vs. two groups on the side with no base really is a superior position, and just running out makes the two groups heavier. I can stop complaining about it now :lol:

This might be a slight over-generalization. Remember, the two side groups have a better chance of eyes in the future than your cutting stones in the middle. It is possible to find yourself in the middlegame with your opponent's two groups alive on the side, your corner group alive but isolated in the corner, and your cutting stones purposeless and vulnerable in the center.

Its been my experience that that attack is too early, and whites group ends up drifting aimlessly in the center as black becomes thicker. If white simply extends at nine, black still has to make several moves to get anything resembling eye space or territory on either side a-f, furthermore the white group in the center has huge influence on the remain sides such as the red circles, as well as plenty of room to run and make eyes.
