Thesis A deliberate foul that accepts its penalty is still a move within the game
Where it stands
Here is a thesis from someone who builds rule systems for a living: a tactical foul, committed openly and paid for with the stated penalty, is part of playing the game, not a break from it.
The strict formalist reading of Suits says that any rule broken means you are no longer playing. But look at how real rulebooks are written. Basketball doesn't just say ‘do not foul’. It says what happens when you do: free throws, possession, fouls counted toward disqualification. The penalty is itself a rule. A team that fouls deliberately in the last minute to stop the clock is choosing among options the rulebook has priced.
In my own games I write constraints two ways. Some are walls: you literally cannot walk through them, and if you hack the code to do so you've left the game. Others are tolls: you can cross, but it costs you. Players who pay tolls are playing. Players who hack walls are not.
So I think the formalist conflates two kinds of rule. Constitutive rules (what counts as a goal, what the pieces are) cannot be broken without leaving the game. Penalty-bearing rules are designed to be broken at a price, and strategy around them is part of the skill.
What I'm less sure of: is there still something wrong with the professional foul even if it is ‘in the game’? Push back.
