Removing a single tile (in the top corner of wall)?

[Stoobloo]

First time tiling, lots of mistakes, but most of them have been resolved in a timely fashion so far. However... I fitted a single tile to the top right hand corner, went away for the weekend and have now realised it's got a cut edge facing outward, not the end of the world, but the edge has a slight taper so if I continue installing tiles around it, the grout line is going to get wider as it gets to the top.

How can I remove this tile carefully?

It's in the corner next to a fully tiled wall on the right, but the left hand edge is still exposed. I used an S1 Mapei adhesive and it's set hard, stuck to a 30mm cement backer board!! Obviously don't want to chip tiles around it, or anywhere from flying debris trying to remove it. Also the bath is directly below it!

What's the best way?

Hi there the only way too remove a tile is too hit it with a hammer unfortunately, scrape any grout out around the tile you want too take out then hit directly in the middle till it cracks and carefully take pieces out. Make sure you cover the bath so random pieces don’t fall and chip the bath.

The hammer worked brilliantly! Thanks. I hammered away and some pieces broke off (over thick cardboard covering the bath and surrounding tiles). I chipped away the adhesive left with a chisel. The backer board is partially covered, partially showing the threads that the cement layer was bonded too. Can I just put some adhesive over it (like a skim) to restore it before finally retiling over?

Yep
