;W[pq]C[Xai [18k]: hello]
;B[cc]
;W[fq]
;B[dm]LB[iq:1]C[For a reason I can't explain, I wanted to play at 1 but then decided to play what I did
Both moves are fine. ]
;W[cn]
;B[dn]C[For the next sequence of moves, I wanted to try to keep the corner for myself but I ended up making a wall... I was afraid of white crawling along the 3rd line towards C3 but wasn't sure what to do]

;B[cq]C[Hane at the head of the three stones. It takes away liberties and pressures them strongly. ]
;W[dl]
;B[eq]LB[jc:2][jq:3][qj:1]C[I'm not sure why I played this move. I probably thought I was turning D3 into eye space. I thought about playing 1 ,2, 3 but did not
Yes, one of those moves would have been better. As would R16. Your stones have access to the center. White can't attack you right now. ]
;W[el]
;B[qj]

;B[jo]LB[hq:1]C[Again, I wanted to play 1 but then played K5 thinking that I would try to contain white to the side of the board?
On 9x9 boards, you can contain the opponent to one side of the board. In 19x19, that is extremely rare. ]
;W[kp]
;B[jp]C[This is a terrible move. It lose liberties for your stones and encourages white to connect his making them stronger. ]
;W[iq]
;B[gq]C[I wanted to try to prevent the F3 stone from connecting to his friends
Connecting and keeping the opponent from connecting is not a bad way of thinking. For your level, tha'ts a good goal, but he doesn't gain much by connecting that stone. ]
;W[fp]
;B[fr]
;W[gp]
;B[hp]C[Setting myself up for a double atari. Oops.]
;W[gr]
;B[er]
;W[hq]
;B[ip]C[Again, you don't gain much by saving this stone. This is a lesson in learning the difference between important and unimportant stones. ]
(
;W[kn]C[White shouldn't give you cutting points like that though. ]
;B[jn]C[This type of move is very slow. And now your group is more of a burden than something that helps you. At this point, you might be better off pretending that you never played any of those stones. ]
;W[jm]
;B[ko]
;W[lo]C[With all these cutting points I could not resist just playing a cut atari move... but I could not find a good followup after the atari
Cut one one side threaten something on the other. ]
(
;B[km]
;W[ln]C[The one that you played helped strengthen your opponent's stones. ]
;B[im]
;W[jl]
;B[kl]C[You are helping white capture your other group. You really won't be able to have it both ways. Some of your stones should die here. Both sets are very weak now. ]

;W[di]C[This helps black. It encourages him to strengthen his stone and loses the chance to attack it. ]

;W[kk]
;B[ll]C[I stubbornly thought I could save these stones...
The question isn't whether you can save them, but is it worth it to save them. Quick answer: It isn't. They don't surround territory nor are they cutting stones. If white captures them, he gets four points of territory. Most moves you can make at this point are worth more than two points per move.
Truthfully, it's a mistake for white to try to capture them. Black should shrug his shoulders and ignonore white's move. ]
