“Fish” is not said in a despising way, we’ve all been fishes and we’re all someone’s fish (except maybe Phil Ivey). I’ve just ended a high stake MTT at the 4th spot and had the chance to play top players. It was very interesting and humbling so I’m obviously someone’s fish
On that note if you could list all the terms/concepts you don’t get I’ll gladly explain it to you to the best of my knowledge.
