Kevin Song (who runs WH's poker room), mentioned last night that the casino where Koreans and foreigners can play - Kangwonland, does have a variant of a limit Texas holdem, where you can only raise once. He said he was working on trying to get normal NLHE approved.
Also, the monopoly that the Kangwonland contract benefits from, ends this year, which may open the door for other casino's to open throughout SK for locals to frequent. My local Korean friends who enjoy poker may still have hope.
