It is both.
You gotta be skillful enough to know some sites will scam you by giving u hands you should play hard, but they'll reward the fish who starts with a worse hand, to keep them playing. One site, let's call them "Cheat on Lies" will make sure you return any cash u win by figuring out the hands u like and using the information to rob you, imo. Not swell. GL!
Blend it altogether, plus luck!There are opportunities at a gaming table that by a good decision the chips can be increased quickly, however there are players who risk with any card and win.
So is it all about good decisions or just luck?
