cab someone explain why was this a blunder?

I wone the match in the end but this was a blunder in analysis but I can't get my head around why

Why is this an inaccuracy?

So my idea with this game is take with the knight, and if he retakes, take with the bishop, ending up a pawn. But apparently the best move is c5, then white puts their bishop on e3, despite being attacked by two pieces. So what is the actual logic here? A Queen trade means the other takes with their rook

Mate in 3 for black?

Are there more than 1 options to mate?

How is this brilliant?

Got my first brilliant move as a 930 rated

Just wanted to share. I just remember being 700 and thought 2000 was impossible. Onwards!

Gotta love the chaos of bullet

Cables

How can i hide these cables on the ground? I thought of buying a dresser, but the problem is if a dart lands on it, it will make a hole. Now, the plan is to buy a longer extension cord, and put it towards the middle of the wall and then try to hide it somehow. It’s currently being renovated, so holes in the wall will not be there of course, plus the wall will be in a light grey color. The chair is gone. Do you have any suggestions? Thanks!

What is the style of bed here called?
