For this turn I am mainly considering the open west side which looks like a valueable more or start an invasion in the southeast corner at moves such as c.
I am reluctantly playing a because it solidifies that side so well which looks very open to an invasion while there are still weak points in his moyo too invade later.

i actually talked about this move too, in a previous post on my thoughts; so this makes the 3rd move in a row that i got to play where i wanted based on that post
this is sente too, good sente not bad sente
bad sente is when you help your opponent more than you help yourself
so now its time to put pressure on this group, and think off good ways to keep what i got mapped out, because i dont have to invade (im not behind) or fight too hard (the board is not complicated for black)
i like the board for black, i like my shape and global presence

The three stones are two important to lose so this is an urgent move. I am not feeling confident with this position.
I feel like I need to keep the R12 group alive adn hopefully not contained too small, and also exploit the thinness in the bottom right.
I am going to have to fight well to make this work.
Below is one unlikely possibility but black has many options at this point.

@EdLee
I admit it may be overly agressive, but after the peep white has no eyes and there's a lot of black stones around, and at the same time black has guaranteed points on the side. Black's shape is somewhat broken, but with so much support I don't think it would matter. The wedge is very good too, perhaps even better. Either way I think the main point is that white shouldn't have left that shape
