How to unlock the Back-rank Mate achievement in Chess Ultra - Definitive Guide

If you are able to earn any of the mating technique achievements against the computer, it would be this one, however it would still be very difficult setting it up and much faster just playing it against a second account on the same console.

If you do not know of this method that uses two accounts, it is explained better in many of the other mating technique solutions, but it consists of playing a game between two accounts on the same console, and going back to the main menu to switch the account you're on every time you want to make a move. It is a little time consuming, but faster than attempting to earn this achievement against the computer.

To start a game, make sure both accounts are on the same Xbox and are friends with each other, and that the dummy account has played at least one game against the computer (I couldn't get my dummy account to show up in the friends list if I didn't do this first). Then on the main account from the main menu, Single Game--->New Game--->Continue--->Opponent (Friend) (Dummy Account)--->Start Game

Here is a back-rank mate I found that can be done in 5 moves. I've left the algebraic notation and the expanded notation below. Since color is random, I've made versions for both colors:

W=White
B=Black

If your main account is White:


If your main account is Black:

Set up a Single game against an alternate account (see how-to in Roadmap) and follow the steps in the video. Make sure to play as white.

You could also find a boosting partner to help you with these moves to make it faster for you. Find a boosting partner here.

Additional conditions: You need to move the pawn to the 8th rank, turn it into a rook or queen and checkmate. In this case, in order for the black king to move to the 7th rank, his own pawns must interfere.
