White made a mistake by blocking at R17 directly.  I think you could have extended farther.  The cut doesn't work for white right now even without the black stone there, so you could even tenuki, though it might open you to being bullied.]

If black tenukis, black could also play something that has a dual purpose of making the cut more favourable.  That means white would need to fix, and black can take two moves in a row somewhere.  For white to come back and fix even if black doesn't threaten it as mentioned, black still gets two free moves, and it's early in the game yet.]

What is black worried about?  White has little territory on the right, and is only extended out half the board.  If you look at white has in serious potential, it's really not that much and it's full of weaknesses where you can reduce.  Black, meanwhile, has maybe 30 points on the right, and a fine position on the left that I'm sure is less than 30 points worse than white's position.

Black could easily just play from the left to reduce while growing the left and fixing weak points.  H16 or so would be big, or E11, or other moves too.  Even J11 might be reasonable, though it's at the limit of reason.]

Tenuki.  Maybe pincer from the left hoping to get it in sente.  There's no real tactics to be had other than 'don't throw good stones after bad.'

It's the same with the position around move 100.  The correct move is not to play (locally). 

It's not as obvious, but if you were looking at a game from, say, a 25k player, and they have a surrounded group with one big eye and a stone already at the vital point.  They might ask at that point, 'how do I make it live?' or 'what tactics can I use with this?' but there's nothing to be said because it's already dead.

In this case, maybe there's something you could do to live, but it would be worse than leaving the stone to die.  Black would get a couple points and ruin some white potential, but white would consolidate the grip on the three center stones and probably ruin the upper left corner and a good bit of the side as well in exchange.]

Last comment:  Despite the horrible result with the invasion, black's still not that badly off.  It's way too early to resign.])
(;B[hd]C[I'd still go for something like this, but it's a little less favourable than a move earlier.]))
(;B[hd]C[Makes something invasiony easier, and builds the left.  Especially if white tries to protect the top right, which I don't think he should.

I like this best, because it also forestalls white extending from his stone.])
(;B[ei]C[Very simple.  Black says he'll make a bunch of points on the side.  Also reduces white's potential.])
(;B[ii]C[Looks to use the aji of N11.  Maybe too direct, as white could choose to start a huge fight with G11 or so.])
(;B[hc]C[Also possible, though it lets white lean for strength and a better center.])
(;B[ho]C[(or one to the left)

Wow white!  Your bottom territory is looking pretty small, but maybe you'd like to defend it anyways?]))
(;B[ro]C[You could also consider something like this.]))
