So I've been reading over on the Brainden site there
all about these logical puzzles, Alex said to no one in
particular last night. He'd been traveling - to broaden
his mind he claimed - and this was his first visit to
Morty's in more than a month.

Jamey laid down the darts he was throwing, while Davey
raised his mug in greeting and sauntered over to Alex's
table to hear more. Ian just leaned against the bar
and listened.

So there's these three blokes, see? One always lies.
Another always tells the truth. And the third one, well,
ya just never know what he's gonna say. Call them
A, B and C, in no particular order - just to keep it simple.
Now give a listen to what I heard them say:

A: O'Doul's is the drink I always choose.
B: C always tells the truth.
C: A hates O'Doul's.

Now I hope you took notes, continued Alex, [the slightest of
smiles becoming visible on his face] cuz I'm going to bet
10 quid that none of you geniuses can tell me which one of the
three was the guy who always tells the truth. What do you say?

Davey scratched his beard, and finally decided not to bet.
Jamey thought at first that he had it solved, but then he decided
there wasn't enough information. Ian finished his cold one,
and, with a wink to the others, wrote a single letter on his bar
bill, handed it to Alex and said, I'll bet this is the truthful bloke!

Assuming Ian was thinking clearly, which letter did he bet on,
and would you have made the bet?

I know who Ian bet on and why, and I'd make the same bet.

But don't you think Alex knew this already also and thus chose the 1/3 chance option in throwing off Ian? But then you get into the Princess Bride scenario :D

I think I wrote this correctly...

Spoiler for A subtlety that leads to the answer?

Your logic is illogical, I believe. TLR is possible.

A: O'Doul's is the drink I always choose.
B: C always tells the truth.
C: A hates O'Doul's.

A is telling the truth and always drinks O'Doul's. B is lying by saying that C ALWAYS tells the truth, but it does not mean that C doesn't SOMETIMES tell the truth. So C could be lying or telling the truth, which in this scenario he is lying.
