Araon is a decent player, tricky, likes to check-raise top pair or better post-flop. He has taken two recent (within last seven hands) hits to his stack, one a suckout - may be steaming a bit. But he has shown that he can re-raise and then fold a hand, both pre- and post-flop. No read on the short stack.
