Hmmm. That would be an interesting informal interpretation. However, I imagine that the formal rules of dejarik would say the "task/aim" is to win. But maybe it doesn't. However CRB says a task check is "performing the task well" like "performing the task in the spirit/aim of winning ... dejarik (or whatever the task.)"
If there is a hidden agenda to subvert (or deliberately fumble) that from happening, that is another sub-task. But you couldn't achieve that without initiating a game of dejarik first. Unless you fake absence through injury, I suppose. But "absence" implies missing from "the right thing to do" - doesn't it?
