Hello! This might be an odd game to have reviewed - I resigned while I was “ahead.” (link to game) My opponent started with the center point and I took all the corners while they took the remaining star points. I knew I was sticking to the basics but didn’t feel confident because my opponent’s style was so different from what I was used to.
I know I need to take the time to count the score and make sure I solidify those existing territories. Any other advice on how to manage this situation?
You mostly did fine. But don’t play moves like 37: you don’t need to stop your opponent from doing what they want to do (build the centre) if what they want to do will make them lose the game. Don’t be jealous of them making territory somewhere if you make as much or more elsewhere. There’s a proverb “don’t interrupt your opponent when they are making a mistake”. So keep on doing what you were doing before of safely growing your corners and sides whilst safely keeping centre access. Also well done for cutting your loses and sacrificing n7. At 73 defend the d13 gap, even if he could gobble up h12 (he can’t) it’s bigger to keep the side and corner safe, him splitting there in sente was a big loss. 81 was a similar forcing him to split you, the ripped keima bad shape, if instead you back off a bit and played c8 then when he plays e7 it doesn’t hurt both sides at the same time. And obviously don’t resign at a local setback if you are still globally good.
You played very well until move 23. Which I find to be too near white strength. Too agressive. White want to fight, to use his strength so don’t offer any opportunity. Play away from the strength is a fondamental. But very nice all the moves before. Simply enclosing would be enough here.
Sorry can’t watch more. I hope I come back later.
A teacher once exhorted me to never resign before move 150 (in 19x19).
Not only because it’s too easy to mis-read a winning position as losing, but also because there are plenty of lessons in most games till at least that point.
Thank you! The proverb is really helpful, as are the tips on avoiding getting split. I’ll keep it in mind for the future 
Your words are very validating. I appreciate you pointing out those particular moves.
Thanks! As soon as I played that I worried it was too close. “Play away from strength” is something I’m working on remembering. In the past, I’ve been told that I play too timidly and need to be more aggressive. So now I’m starting to swing too far the other way and need to find a balance.
Thanks for sharing! Will keep that in mind.
I think it wasn’t so much that I mis-read a winning position. I was pretty certain that I was at least even (should have taken time to count) because I had all the corners and significant part of the sides. Getting split twice in a row threw me and my opponent was playing very quickly. So there was definitely a mental/emotional aspect to it when I needed to stay calm and play carefully.
