I was on 40 seconds and I panicked, pushing the h pawn to h3!!!! when my brother checked me with his rook I thought I was fine and just moved to h2, allowing mate in 2.... I was still dead but I could've delayed my doom by blocking with the queen. I've done many puzzles on this kind of checkmate but all of that training is eliminated when I'm under time pressure and I'm cocky. My advice: don't spend to much time or get cocky! If you have any big blunders that you would like to share (you or one of your opponents), post them here!
