Rachid Ben "SkaiWalkurrr" Cherif is a young Dutch poker professional.
On PokerStars you have been able to find him fighting the high stakes regulars at both the NLHE and PLO tables. But until just recently (February 2012) he stuck to the former discipline. Maybe it's something temporary, but it looks like Cherif and a whole bunch of other professionals out there switched from NLHE to PLO. As I'm sure you all know by now, PLO equals massive swings, but one must say that "SkaiWalkurrr" started out strongly.
Apart from the cash games, Cherif has spent a lot of time playing Sit n Go's, and apparently he is good at the NLHE heads up format. In WCOOP 2010's $25K NLHE HU event he ended of battling "RaiseOnce" for first place, lost that battle, but got $194K for it.
The following year he almost made the final table again at the WCOOP $10K NLHE HU event, but was eliminated in the semifinal.
