Thoughts about a few tourney games and opening ideas

Hi all, despite my current decent (top 400) rating I consider myself still a rather weak and overrated ZH player, but I am trying to improve. This week in a tourney I played three games against the same opponent. After a painful loss in a game where I was happy because I thought I was winning and because I had seen a counter-trick, my brain froze. But before continuing in the tourney I briefly checked the game analysis not knowing I would play with the same color against the same opponent in the same tourney twice more. I posted a blog about this with game comments and analysis. I am curious about your comments and suggestions to improve. Thank you. https://lichess.org/@/achja/blog/small-steps-with-crazyhouse/Nbh2PonF
