Opera has unveiled custom versions of its desktop and Android browser that fans of one of the world's most enduring games might appreciate. It has teamed up with Chess.com to integrate chess directly into the browser.A chess-themed version of the desktop browser includes a Chess.com icon in the sidebar. So, rather than having a dedicated tab for the website open, you can pin the panel and plot your next moves as you browse the web. You'll have swift access to puzzles, streamers and ongoing games. On Android, there's a whole new version of the browser available, Opera says.
