Dragon Punch From Ryu
In response, I point to the back of Alioto's hoody which reads 'Dario 'Ryu' Alioto' (always a giveaway), so I guess he gets asked that question on a frequent basis.
I have no idea where the moniker arrives from, but Ryu just threw a fireball at Jon Persson, raising to 11k pre-flop before check-raising Persson's 14k bet to 115k on a flop.
Persson was initially lacking in emotion, but then began to huff and puff in that manner players tend do just before they make a reluctant fold. And that's exactly what he did.
