Бот в крестиках-ноликах не учитывает вариации

Написал крестики-нолики с помощью модуля pygame. Решил добавить игру с ботом(ходит за нолики). Для ходов бота написал функцию, которая учитывает различные вариации. Например если в 1й строке первые две клетки заняты крестиками или ноликами, то бот записывает нолик в 3ю клетку. Если ни одна вариация не подходит, то бот ходит рандомно(в самом начале, например). В случае со строками бот учитывает вариации при ходах, но абсолютно игнорирует связанные со столбцами. Заранее благодарю за помощь в решении проблемы.

В соответствии с данными строками, бот должен был бы записать нолик в 3 клетку 1го столбца, но он этого не делает.
