Life In 19x19

I played this game in the ASR League today. I was proud of the way I was playing and had a decent lead for a while, but once I got into byo yomi, I made a couple bad decisions and ended up resigning. When I resigned I was thinking that my group on the right was dead, but in my review, I saw that this wasn't so.


doesn't look good. Maybe K8 instead?
is obviously a mistake (in hindsight). I should have reinforced my group on the right with O14 or something similar.
Then there is the mistake letting W live at the end. Other than that I think I need outside help to find errors. Thanks in advance.

A few ideas, no warranty.

Take a look at 17 and 19. You spend 2 moves to run out 2 lines (albeit making a pretty shape in doing so). White answers once below and once above to add a move to each of his weak groups. What would happen if you just jumped out with the one space jump? White would almost certainly still jump out below. Then it would be your move and you could play a checking extension against the group above, making territory from your shimari whilst preventing white making a base so forcing him to flee. You could even consider more advanced haengma such as n8 2-space jump backed up with the kosumi and peeps at p6 and n6 should white jump to m5. Maybe white would answer that with n6 instead to aim at the thinness of the 2-space jump, but that has little followup against the lower side.
