Is it a strategy or fake game?????
Fake plays/games occurs in a lot of sports all the time.
One hundred percent of the players /athletes will not use 100% of their
effort in at least some portion of the game time.
Here is a partial list, as examples
1) Basketball (especially NBA)
2) Soccer
3) Swimming
4) Track and field: racing
You can say it is either a strategy ( if you want to be positive) or fake
games ( if you want to be negative)
