I kind of knew that I should trade the bishop, but I didn’t know how to continue after that, so I thought about the line Qxd5. It turned out that Qxd5 should come after Bxe7 because after Qxd5, e6 cannot take the queen and I would have gotten two bishops.


I thought about Qg3, but I didn’t want to sacrifice my bishop, so I gave up the thought.
The best line is …Qg3, Nxb7, …Ng4, Qxg4, …Qxg4.

This is a example of threatening.
“Checkmate, capture, threaten.”
Because there is no checkmates, no captures, so it’s best to threaten.
