47...b4 wins the queen. It has nowhere to run.

It was a speed chess game that I watched live. White had plenty of time but he got impatient and missed it. I totally missed it too. The eval bar showed white with a huge advantage but I was mystified. I was looking in the wrong place - on the upper right side of the board. I forgot all about the b pawn. And they were playing so quickly I had brand-new other things to try to figure out.
The game was sharp. That's a chess term that I define as pretty damn complicated and tricky. Trying to understand the positions in real time made my head hurt.
The best move would be the white pawns finding common ground with the black pawns and overthrowing the remaining aristocrats & clergy. Then together they can stop the endless cycle of pawns being sacrificed for the whims of the upper classes
