Return to Chess 3--Using Chess.Com to Study Openings

Hey, everyone.  Today was day 3, and after a day of work, I finally got to sit down and play chess.  I warmed up with a new tactical set, where again I scored 6/10, attempting to solve each one thoroughly.  On one of them, I became impatient and jumped to try and hit the correct answer, but got it horribly wrong.  Here it is, if you'd like to give it a try.  Black to move:

Secondly, I went over two 15+10 training games that I played with my friend, Oliver.  Oliver, if you're reading, you definitely outplayed me, and thanks for the fun!  In the first game, I detailed my opening, since it was my main opening with white that I am still studying.  In the accompaniment for today, I cover the steps of using Chess.com's analysis tool to study openings, which is what I use.  As always, the video is below.

Thirdly, after working on more of the same opening, I will be playing and analyzing two more training games, hoping to get better.
