Here's the game: lichess.org/KIEynDoV/black#20
The computer says that `10...Qxc6 was an inaccuracy, and that I should have played 10...bxc6 instead. I thought that bxc6 would result in a worse pawn structure (the a6 pawn is isolated), which would become even worse if I play e5 later (the c6 pawn also becomes isolated). Sure, Qxc6 possibly loses a tempo or two against a later Bf3, but it's worth it, right? What did I misjudge?
