;W[ed]C[billywoods: protect the corner/side. That's where black wants to make a base.
(I was looking at gaining territory on the top, as well as influence towards the middle. I beleive that my error at move 18 in response to Black's pincer effectively ruined this intention.)]

;W[hc]LB[cc:A]C[billywoods: and again.
(Yes, I can see how blocking here at "A" is good. I can extend later.)]

(;W[me]C[skydyr: This black pincer stone is ill advised, and should be attacked, but when white plays the keima against it, it asks it to strengthen itself. If white continues this way, then white's goal needs to be to use the strength gained by leaning on the pincer stone to attack the corner, but after move 37 at Q14, white has a weak group and no strong attack. Consider something more balanced, like the one space jump, instead.]

(;W[po]C[skydyr: No comment on the ladder, really. Black was very kind and should have just responded to white's move normally, because it doesn't threaten to make the ladder work.
(Here I realize my mistake in reading the ladder. The move I made looks small and lacking in potential due to the failed ladder above. Perhaps I would have better played a ladder-breaker first, then disrupt the territory on the side.)]

;B[kg]LB[ih:1][on:3][fq:2]C[skydyr: Black's move is gote, to try and keep white from causing problems with the dead stones. White can play at F3 or so to neutralize black's bottomside wall some and close the corner, or at P6 to take it from the other direction and enlarge the bottom right.

;B[hr]C[skydyr: White is building a wall in exchange for giving up territory, but black has lots of outside strength already, due to the ladder and the bottom right wall and extension. This means that white can't expect to get a lot of points out of the wall, and with this sequence, white ends up terribly overconcentrated in the bottom left. White has played 8 or so stones to secure 4 points.
