Blunder on purpose

Move ...16 ...17. I hanged the knight for 2 moves... if you look at the beginning of the game you will se the opponent never traded. if https://www.chess.com/analysis/game/live/41619668763

I used to do this, and it worked! But after a certain level, it stops working, and your opponent will know when to and when not to do something.

My advice is to not play hope chess, and just play normally, because taking advantage of this now may net you a few wins, but it’ll be bad for your long term chess when you get to that level where it stops working, and you do it anyways.

This is a major difference between chess and Poker: in chess, you see exactly what your opponent’s “cards” are, so gambles like deliberate blunders almost always fail. In poker, your strategy is viable in certain scenarios.

Hope chess is rarely a good idea. Blundering on purpose is not smart however you can set traps with say, slightly sub-optimal moves, that if they fall it's good for you, but if they don't your position is still solid.
But yes you can come up with a plan based on the way your opponent plays. If they never trade, you can try putting them in positions where not trading would be bad for them and good for you.
During my last game I got a question in my head.
If you recognize pattern in your opponent's game, would you make inferior moves to take advantage of it? I got this question due to noticing my opponent never trades.
