how much money can u win in a chess tournament?
Unless you’re a pro or HIGHLY underrated (intentionally or otherwise), about the biggest prize you might win is $1000 or so.
Yes, there are individual prizes of over $10,000 (top prize at the HB tournament in Minnesota was $50,000, top prize at the World Open this coming weekend is $25,000) but those prizes are generally won by professionals, and usually shared between several people who tie for 1st place. And the top prizes in the class sections often go to players who would have been quite competitive one or two brackets higher.
