Can you think like a Grandmaster ? (updated)
I am playing this against Fritz to help understand what moves need to be made and when. I give the move order below so you can toy around with it as well.
This is a classic case where a side has a material advantage but can't use it. Given this exact position in the game, I hope I would make that Queen sac as black could force a draw if the game appear to be a loss.
