Не е добра идея да пазиш този None като стринг. В крайна сметка по-логично е да е просто None, а и това е стойността, която се очаква по условие.

Струва ми се, че на тези флагове не им е тук мястото. Подготвяш за следващата част с позицията на царете, и това го разбирам, но ми се струва неуместно. Усложнява логиката. Бих разделил двете валидации в две отделни функции, за да е ясно каква е отговорността на всяка от тях.

Опитай да намериш позицията на двата царя, след което да изчислш разстоянието между тях. Така ще спестиш доста дълъг, труден за поддръжка и лесен за оплескване код.

Ако обхождаш оригиналния fen, няма да е нужно да дефинираш колоните експлицитно. Просто обхождаш ред 1 и ред 8.
То и тук можеш да си го спестиш, ако обходиш всички values() за дадения речник.
