uh-oh. I start to wonder what did I type on the command line at the same time...

| Feb 17, 2017 at 10:06 | comment | added | elias | @bitcell, indeed I did not clearly state that the old man's task is not to identify the truth-tellers and liars, but to identify the door to heaven. I will clarify that, thanks for the input. However, even identifying the truth-tellers with your question would not work, because he is allowed to ask only two guys. If the two guards answer differently for that question, he has no idea if the third guard is a truth-teller or a liar. | |
| Feb 17, 2017 at 9:51 | comment | added | bitcell | Please correct me if I'm wrong, but if one always tells the truth, another one always lies, and the last one is either lying or tells the truth, wouldn't it be easier to just ask something like "Is my beard white?" (or something that is true ie. is 1+1=2) and see what each of them respond. That way the truth tellers would say yes, and the liars would say no. Maybe I didn't understand the puzzle, but this would be much easier. | |

| Feb 16, 2017 at 23:02 | comment | added | elias | My English is still broken, sorry. And this is my first self-made puzzle here. I'm happy to hear any feedback in both subjects. | |
