While these plays are going to be close to me it's a much larger theoretical error. First, it's an error that is likely to repeat over the course of a game/your career and is easily fixed. Secondly, when the bot plays this out it knows in the future to not do it again/correct things. If you miss this then you don't and the actual error is larger.
When I used to give lessons holding games were some of my favorite, not only cubes but checker play. There are surprisingly a lot of intricate plays that arise when playing what we think of as a simple holding game. I always taught people in positions such as this one that when significantly up in the race your 6pt should look like a stop sign. No checker should go beyond this point unless necessary. You aren't trying to build a board. You aren't ever going to get or hit a shot. The opponent is too far behind to think of leaving with anything but a large double therefore you keep your spares high for future flexibility.
