Chess 2 player - Chess Puzzles

This is the worst chess app I’ve ever seen for one it has black moving first instead of white and if that wasn’t irritating enough when u check someone it doesn’t register the person being in check and the game will let that person who’s in check move other pieces even if it’s not to get themselves out of check and let’s say your next move is to take there king cause you’re opponent didn’t move out of said check well guess what it says u win I hate how they don’t honor basic chess etiquette *hmpf* 😠😡🤬

Fix this when I do easy it’s hard FIX IT I hate this it’s annoyingly HORRIBLE don’t make games anymore whoever made this bye FIX
