What if they lost the bet because they missed a goal because they slipped on the ice? What if they missed the goal because they blocked it? Taking a strategic penalty isn't _cheating_, it's acting within the rules of the game. The rules are _if_ you take such an action, _then_ the following consequence occurs.
It's sort of dependent on the game and the penalty, though, what the norms are. In soccer, basketball, hockey and football, strategic fouls/penalties happen all the time to prevent scoring opportunities -- holding, etc. That's not considered cheating, it's just part of the game, you trade a sure goal for a penalty.
There _are_ some actions that are considered cheating though -- think inflategate in the NFL, or stealing signs with cameras in baseball. Stuff that isn't generally caught and penalized in the game -- that's the kind of thing that most players won't do, even at the top level.
