Advice for blunder rook move against Devon-Bot

Sort:
IChessBeginner
Hi guys, may I ask for an advice. This is the game I practice with bot and wanted to ask why move 11(Rab8) is considered a blunder supposedly the opponent could easily move pawn d6 and get ready to capture my rook while forcing me to capture with my queen. Any input would be greatly appreciated. Many thanks for taking time to read this post.

Re1 pins queen

Any move that does not prevent Re1 pinning your queen is a blunder here. As you saw in your game, you were forced to give up a whole piece (your bishop) in order to keep your queen.

Thanks for the explanation.

For the future: when you are in the engine analysis page(the little magnifying glass icon in the bottom left corner), you should check the "Show lines" box. That way you can see the engine's top 3 choices and you can also experiement. (If you don''t understand why a move is good or bad, play that move and see what happens).
