The problem with those other games is that there's so many decisions they have to make its easy for them to be dumb. Chess is such a simple game from the standpoint of a computer that it can play out thousands of move sets in a few seconds. I hate it (and I know, I ruined the joke, sorry).
I just really want badly to be good at chess, and the computers always ruin my moral
I've been pretty into chess lately, and it's such a deep and wonderful game. Even if computers are better than us, there's still a huge ladder to climb between learning how the horsey moves and becoming Magnus Carlsen.
My friends and I are decent at chess and we have been enjoying playing bullet games of Bughouse - would definitely recommend you check it out if you aren't aware of it! The luck and randomness of it I find easier than classical chess all the time
A bot can be very easily made to be effectively unstoppable in an fps, just look at hacking players.
Just as a chess bot can be made dumb as a box of rocks.
They just serve different purposes, for example in counter strike, bots are nerfed in purpose in order to discourage kicking other players to replace them with a bot that would do better.
Chess bots are also the target of computer science researchers, very few if any, serious academics are focusing their time developing a bot for a game that is either a flash in the pan as far as popularity, or actively discouraged by the arbiters of the game.
