I feel that B138 lost me the game, that if I had left F13 die and just played E15 or similar instead that I'd have been in better shape. I'm also wondering about the, I assume, loads of poor moves I made that I'm not able to see. Was I right to not mind him invading the upper left side and just seeking to contain him without making contact? (i.e. is B126 a bad move, should I have gone to B14 or E13 perhaps?) I feel I handled this invasion rather badly and that up to this point my play was ok for my level and would like some advice here.
My apologies if this game is of poorer quality than what should be posted here. I've only been playing for 2 weeks (played a little 9x9 7 years ago but less than 10 games) and this is my fifth game at 19x19 in total so I'm really in a place where I could use pointers.
