I often see a lot of the same faces every time I visit the casino and the same names day after day at multiple tables online. What makes someone a pro as opposed to a reg as opposed to a recreational player?
These words are not slang words... you can use vocabulary or wiki or logic to understand the meaning.
1) Pro = Professional is the one who earns money for living from his profession. So in poker world "pro" is the one who has stable profit in a period of time. For example 90% of finalists of biggest live poker tournaments are professionals.
2) Reg = Regular is the one who plays often, but doesn't necessarily means that he has profit in the long run, Reg plays a lot and is well recognized by other regs and pros at the tables. Majority of Regs are also Pros.
3) Recreational players are those who play poker well, but it's not their main source of living, it might be a wealthy businessman who earns additional profit playing poker while his factories generate stable income without his participation.
so Recreational Reg is't always a player who has profit from poker. Pro isn't always a reg. Reg isn't always a pro. Recreational Pro is a smart and wealthy guy you know
4) 50 shades of the fish located below and I'm not going to describe all of them.
p.s. these values are very subjective, there is no objective opinion, some people in poker world can think that player who earned $1000 during a year of playing poker is a pro, while some other people might say that $1000 per year is nothing, cause they pay much more for the broadband internet during this year.
