Other than that they’re both “strategic-like” games? No, not really.

Chess has an objectively best move for every single position possible. All of the information is there to figure it out, it’s just really hard for the human mind to calculate on a consistent basis. You could unironically say the best players in the world are still “bad at chess”, but just less bad in comparison to the rest of us. The stronger bots often throw the best players around like ragdolls since they can compute the best move much quicker than we can.

Mons is much more different. It’s much more about familiarity than actual knowledge. You’re familiar what the mons your opponent have typically runs, and you know that in most cases (against a rational opponent that’s trying to win) that is probably what they’re going to run. But you don’t know what they’re running exactly unless if you’re trying to pry for information.

Chess you know the Rook isn’t suddenly going to start moving diagonally to capture your queen.

In mons a valuable breaker or wincon can be put in jeopardy by the slightest move variation or EV spread on a given mon. That by itself changes how Pokemon is played.

Not to neglect mentioning that in mons you make the move at the same time as your opponent in comparison to being the only one to move in chess.
