so, I was reading The way of the moving horse by Janice Kim and I found this, I always have problems with invasions, I can't "see" if they are going to success (any link /book dealing with that would be great! =) )

so I can't "see" why that invasion could be helpful (or in the triangle), to me W is only going to get stronger while B owuld struggle to live
any help with that?
Good question,
When you "invade", you usually want to do one of two things:
1-
Live inside, dealing a relatively large amount of damage
2-
Create forcing moves that reduce the territory faster.
Most cases, the aim is 1. Of course, the opponent will acquire some thickness on the outside, which means influence. You must invade at a time and place where the influence created by the adversary is:
1 Not very useful (stifled by your own *strong* stones)
2 Overconcentrated (in the diagram, white already had quite a bit pf influence and points in the area, and a reasonable amount of points, so invading at the san-san isn't as damaging as normal to black. The keima is sometimes used also, depending on the __WholE__ board position.
As for "seeing the future", you do want to be able to have some "awesome" reading skills up your sleeve, but by just doing many tsumego that you can solve in a minute, you'd naturally start finding possibilities in your games, by subconsciously recognising the shape. This is necessary, for even pros cannot always read everything that could possibly happen in some of the most hopelessely complicated positions, but make intutive jugdements of weather the invasion would work.

"Mediate" section has a very easy to follow invasion toturial.
ps: remeber that if the influence white gets is more valuable than the amount of territory you remove + the amount if territory you make, tgen the invasion was not succesful.
