posetcay: There are many missing correct variations here due to O14 timing, for example O14 could be played at Q10 on Q13-O12 pathway, I recommend starting with a black stone at O15 (O14-O15 exchange) to reduce the number of possible correct solutions, otherwise it could be difficult to cover all the correct variations.
d4rkm4tter: Getting rid of the other white branch helped and then I added variations.
