Narrow double wing  

A 3-3 point invasion is natural and good

Double wing  

This one depends a lot on the surroundings. If you can get an answer like 2, then 3 is still reasonable.

Also think about a shoulder hit on the 3rd line stone, and then a knights move approach to the 4-4 from the other side.

Reinforced double wing  

A 3-3 invasion is about all white can get.

Wide double wing  

Invade the wide extension. A 3-3 invasion would be too generous. Also expect a pincer and jump into 3-3.

1 point jump low double wing  

Get the 1,2 exchange in first, then the 3,5 invasion is ok. 6 is one way to get a ko, but black can't really reasonably fight it without more reinforcement.

1 point jump high double wing  

When the wing is high, it may very well be more interesting to separate it and leave an attackable group. 7 doesn't have to be played immediately, but it might replace 5

If black tries a pincer, it just leaves the 4th line stone worse off, and the 3-3 invasion still possible.

If the marked stone isn't so interesting to attack, try the point 1 below 7.

Knight's move  

1 is the magic point. It gives access both into the corner and the side, so white will get one or the other. Lots of variations though.

3-3 point gives only a ko.

Large Knight's move  

When its reasonable to get pushed towards the marked black stone, 1 gives some nice results.

Large Knight's move, reinforced extension  

Better go into the 3-3 point here. Perhaps you can get the 1,2 exchange in first.

Watch out for the sequences where black hanes on the second line!

High moyo  

A 3-3 invasion is natural. black can play 4 to reduce its size, but white can still tenuki after 8.

White can also try 2, but expect to take gote.
