Black resigned early so I would appreciate some advice on where I could go from the state of the board.
In addition early on in the bottom left corner I played B3 instead of D4 and would appreciate some insight into the difference between those two moves.
Thank you in advance for helping me grow as a player!
I guess I was worried about black playing at B3. Thank you for the insight. In the moment it looked like a decent place to invade so I thought I needed to stop it and D4 seemed too slow.
