Mate in 10

What about it?

I had mate in 10 from here but took a draw because I couldn’t see it :/

I played a brilliant move today. Happy International Chess Day everyone!

First brilliant!

What about it?

Felt so sick playing this had a 82% accuracy on the game. I’m 850 elo

Got my first brilliant move today!

I am so close to achieving greatness (nice)

I’m actually shaking

What would you do in this position? White to move. White cannot castle.

What about it?

This came up in a real game I played.

Promoting pawn to rook better than Queen

What about it?

You see the score for promoting to to is better than when, how is this possible??

Is this normal?

What about it?

I am sure there was quicker way to mate but I was trying to make Queens

I need help
