"terryhsu" is an unidentified player whose account is registered in Taiwan.
"terryhsu" first appeared on HighstakesDB's radar in September 2011 and he has been playing both the mixed and PLO cash games online since then. He didn't start too well in 2011, losing over $100k by the end of the year before taking a three month hiatus at the beginning of 2012. The break seemed to work wonders for him as he returned with a bang.
He plays the mixed games as high as $400/$800 and judging by the few players who are willing to play him, he seems to be feared in that format. He likes to play PLO heads-up and from what we have seen, very deep as well, often playing just a couple of tables at a time but sitting with over 500BBs on each.
"terryhsu" appeared to play the biggest games out of nowhere so one could assume he has previously played high stakes online games in the past and could possibly be a player who plays the live cash games in Macau and has registered their account in Taiwan.
