This certainly doesn't happen every day:
1.c4 c5 2.Nf3 Nc6 3.Nc3 Nf6 4.d4 cxd4 5.Nxd4 e6 6.a3 Be7 7.g3 Qb6 8.Nb3 Ne5 9.e4? Nfg4 10.c5 Qxb3 and White resigned in the game Qun Ma-Danny Raznikov, Groningen 2014.
What's especially odd about the game is that even the pedestrian 10...Bxc5 is very good for Black. So what happened to White in the game? If anyone knows the back story of the game, please pass it along! Meanwhile, you can replay the game here (as well as above), but with my brief analytical comments.
