So while hardly anyone jumped at this problem the variant shows one important detail that creeps up from time to time that we should put in long term memory storage. The fact that the opponent has the ace point slotted in the original problem allows us to leave shots and play a lot purer than if the blot wasn't there even though he has the best five point board in both situations. I think we realize this in your average, every day position ... 'opponent has blotted inner board so I can play more freely' but when it comes to a crushing board like this example I think we almost ignore the blot thinking it doesn't matter when often it does. (esp. when there are no direct covers for it)
