Online Sites For Earning Money Through Chess Does anyone know if there are any sites by which I could play chess professionally and earn money similar to gambling sites or online poker sites ??
I highly doubt that there exist one. If it would exist, it would be full of sandbaggers or engine players. There is no way to verify who exactly plays the game. You, or your Stockfish/Houdini/Rybka/.

So even if you are GM, you most probably will lose money.
