If it's free, why credit card?

Standard business practice.  Capitalism sucks but it seems to suck less than the alternatives.

I have credit card, but this is simply... suspicious.

I ever trusted of Chess.com but this...

           I agree with good dog, but we can't give free chess lessons to every drug addict in town. They'll go broke in 48 hrs. The're coming to the market place by saying; look at our offer; when you come to the market place, you have to prove your worthy. (have real money). Its the opposite of a court of law. (your INNOCENT until proven guilty). In the market place, your guilty, until you prove you have good money. Its free, until you buy it.

You're right, i admit when i'm wrong.

Free means free, full stop.

           FREE  is an allusion in the market place. You are free to brosze. The word is an enticement to get you to look more. If you purchase 1 month at this fair lovely site, you will actually GET 6 weeks of access. College is free. It only cost you 4 yrs of your life, and sometimes your soul.
