Don’t worry about cheaters, play your game and think that they are always loosers! 😎
Daily chess seems to rely a bit on an honor system(not completely, but far more than other categories). Here are the rules if you didn’t know, and it’s possible your opponent learned about them and started using resources they had not been.
--The below are NOT ALLOWED--
Engines - You may not use any engines to analyse ongoing games! This includes Chessmaster, Fritz, Komodo, Houdini, Stockfish, Chessbase with any active UCI engine, etc.
Tablebases - Tablebases are chess databases that contain every possible move for endgames of up to 7 pieces. These sequences will always lead to a win when a win is possible, and are for that reason the same as asking an engine to analyse a position. Tablebases are not allowed!
Help from other people - You are not allowed to ask for help from another person! Do not ask anyone for advice on any of your ongoing games! Do not let anyone else play on your account!
Fixing game results - Arranging games, playing with multiple accounts or losing intentionally are also against the rules!
--The below are ALLOWED--
Books - You may consult chess books, lessons, or videos to search for a good move. These resources do not involve an engine that finds an answer for you, so are okay for Daily games!
Opening databases - You may look at opening databases, or game records to find a good move. You may NOT use any of these that also use an engine to evaluate the best moves!
The in-game self-analysis tool - You may use the self analysis tool to look at possible moves, and to set conditional moves. This is only available in Daily games!
This is why i dont play daily chess 🤷🏻
If you suspect another member of using disallowed resources, you should report them.

I played two Daily Chess games in a chess.com club tournament and got crushed. What surprised me was the low rating of my opponent. My daily rating hovers in the 1100-1200 range, and my opponent was in the 800s. Looking over his games, his games routinely average 50-60% accuracy, but in our Daily games, his accuracies were 91% and 96%.
I made some obvious mistakes in my games against this player, so maybe the right moves for my opponent were all obvious beyond that point. But I have to wonder - did I just find a cheater?
