My First Victory vs. Computer on Expert (2000+) mode
So on chess.com, there are four ways to play a game (from the "Play" drop-down menu)
- Turn-based chess (including tournaments)
- Live chess
- Vs. a computer
- Vote Chess
Today I was playing the third. Link: http://www.chess.com/play/computer
I've beat the computer before, but never the Expert mode. 
I've had winning positions before, but I didn't have the benefit of blunder check when I needed it most. Other games have turned to draws.
But not this one!! See below:
