blunders!

I thought nearly every move my opponent made here was a blunder but in the post game analysis it says she didn’t make any? Some of the moves were really silly. How can this be?

Not sure how to share the game 😂

From what I can tell, a blunder is when you move a piece undefended into the path of another piece, and you don’t get anything in return

Um will you stop now 😩

To the OP, sharing games is a lot easier on the website than in the app.
