What happens when Chess.com's best takes on a world top 15 player? Well, it's a little predictable, but if at first you don't succeed, try a half-dozen times! IM Danny Rensch faces off in a live session against GM Wesley So, the new American number two who is also encroaching on the world top ten. The two play six wildly different openings, and So shows why he is so tough to beat. That doesn't mean Rensch doesn't go down fighting. Watch and see him try to convert several advantages!
