Mtvdeuem is the nickname for Slovenian pro Matej (Matthew) Cepon. He is a heads up specialist, particularly specializing in turbo/hyper-turbo Sit N' Gos.
However, lately he has been moving over to cash games more. He started playing poker in 2004, and was hooked pretty quickly. He worked his way up through the ranks of the HU SNGs, starting at the $11s, and then reaching the $115s where he stayed for around a year to polish his game in preparation for the higher limits.
With the help of discussions with his friends, he rose to higher stakes, eventually reaching as high as the $5500's a couple of years later. During this time he also enjoyed working at Casino Ljubljana, but he had to quit as he didn't have any free time outside of the work. Nowadays he can regularly be found playing high stakes heads up SNGs or $25/50-50/100 heads up PLO or no limit.
