example 1:

for ... do
  if c1 then do
    ...
    if c2 then do
      ...
      if c3 then do
        ...
        if c4 then do
          ...
          if c5 then do
            ...
            if c6 then do
              ...
            end
          end
        end
      end
    end
  end
end

example 2:

for ... do
  if not c1 then do continue end
  ...
  if not c2 then do continue end
  ...
  if not c3 then do continue end
  ...
  if not c4 then do continue end
  ...
  if not c5 then do continue end
  ...
  if not c6 then do continue end
end

which example is more clean and more elegant looking? yep, the second 
one is.
