you should not use them here, just do

if line == 'w s'
   puts 'yes'
else
   puts 'no'
end

If that does not solve your problem, place

p line

just before your if expression in order to see what 'line'
actually contains. There could be a newline character at the end,
if so, you can use 'chomp' (line.chomp) to get rid of it.

("w b\n" and "w b" are different.)

No problem at all. Just ask.
