Eh.. if you're seriously learning a game like that, then I think you're definitely learning wrong.. When I'm talking about "mixing and matching between games", I don't mean that they have their strategies mixed up.. I mean, they literally think the board is some strange amalgamation of both games where the king might be on multiple different tiles at the same time, so they start making moves as though the king is on a tile that it isn't actually on (because it was like that in one game where "most of the moves were similar" but not in the game that it's actually playing), or it might think that it's capturing a piece on a tile that actually has nothing on it because "I saw a game where a piece was captured on that tile and some of the moves in each of these games were the same so I guess I can capture something on that tile".

The AI also has absolutely no understanding of what the rules of the game are - I mean, if you ask it about the rules of chess it can copy/paste an answer that it's read about it, and if you ask it to make a move it can look at what moves people have made in chess before and try its best to find a pattern in it, but it doesn't understand whatsoever that the rules of the game are related to the moves that are made in the game, it just treats those 2 things as unrelated questions and tries to answer them individually without seeing any connection between them.

It's an incredibly warped way of seeing the game.
