If you enjoy tough games, i encourage you to take a look into crazyhouse (https://en.wikipedia.org/wiki/Crazyhouse https://en.wikipedia.org/wiki/Crazyhouse). It is the analogue to shogi, captured pieces can be redeployed as a single move. You can play crazyhouse on lichess.org for free, just a email is required. GM Yasser Seirawan is the most prominent crazyhouse fan playing on crazyhouse(https://lichess.org/@/yasser-seirawan https://lichess.org/@/yasser-seirawan). As is internationally common, pieces _can_ be dropped with check, this makes the game extremely violent. Considering that your opponent can use captured pieces against you, a material loss feel twice as hard as in normal chess, in the long run. Nevertheless the game of crazyhouse is completely dominated by dynamic factors. E.g a queen is barely worth two pieces and (in high class games) often it is sacced for a single piece and a tempo. If you have black you will have a hard time to survive the opening against a good player, some even believe that the game is winning for white and i think this is not way off. If your oppononent is 200 Elo points stronger, expect to get mated until move 30 or even move 20. A single slip and you can get mated in move 15 or earlier. I hope i have wet your appetite :-)
