Penguincw: This isn't Nakamura's tournament.
Okay, yet another uncommon opening. (US Championship: Weird First Moves)
Yesterday in the women's section, Jennifer Yu wasn't having a great tournament either so started with 1.b4 and won the game. (Jennifer Yu vs Maggie Feng, 2018) She won her game today too (R8) and at +1, is all of a sudden vying for the title.
Nakamura's at -1 right now, so could this be a spark? Deja vu? So Nakamura tried the same thing. (you know, chess ideas spread fast) And wow, what an attack Shankland was able to mount on Nakamura. Would've been a huge win for him.
Look at the position after 23.Nb1. Someone said it looks like Nakamura's playing bullet this tournament (especially after the flagging yesterday). Looks like Fischer random now with those white pieces arranged like that.
Nakamura still has black vs. Caruana and So, while Shankland has 2 whites against those lower rated than him, to try to secure the championship.
