It isn't joseki, so I can't look it up as such.

I generally push up.

I think black is in an inferior position after these, but the fighting is messy, any suggestions?

Pushing up once is most common.

When White has has developed some stones around either mark areas, then if :b2:

a push & cut from White will give him a tough fight for one or both of his groups:

Therefore, when White pushes Black usually makes a light & loose jump. Then White takes sente to play elsewhere.

When White continues to push Black can play this way:

There are a lot of continuations for White here (e.g. A-F). You should choose the one that fits into your gameplan.

White can also aim at the shape weakpoint, if the placement stone will work in conjunction with some other global plan White is pursuing.

logan gave a nice description. daily joseki is also a useful site.

Keep in mind that the territory of a stone on the second line is only one point per stone, but the influence of a third line stone is worth at least two points. So your first priority is to not continue such 2ndrank/3rdrank exchanges unless life requires it.

One of the severe variations I have seen is the black connection, I suppose,

If I push then if black, fixes his connection, I just take an extra something like.

Why play sansan if You don't want to be pressed low? The idea is to grab moderate amount of territory with one move, not to build influence or really anything more interesting.

This question maybe beyond the scope of the thread, but san-san has some nice strategic properties, like being free from invasion.

SmoothOper You didn't understand my question, I am fully aware about the advantages of sansan, but it seems You aren't aware that it has its disadvantages which should be taken into account and "accepted" the moment a player plays this move.

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".
