Play “the right way” each and every time?
The ends justify the means?
Unless everyone knows exactly what the right way is we won’t achieve that, and no-holds-barred, win at all costs isn’t ok either.
Like most things on a spectrum, reasonable performance and appropriate behavior is somewhere in the middle.
When it’s clear that it’s cheating, however, the answer is obvious.
Even if the people don’t know you’re skirting the rules–official or unofficial–the game will know (Rule #98).
True prosperity comes with honest success.
