Yo has anyone realized how obscure methods are OP?

Firstly, pinning. If you pin a queen, it will take two moves for the queen to escape.

Another crazy method is double checking. Most common way is to do a discovered check, for example, (you are white) you have a bishop on E1, and a rook on D2. The black king is on A5, while the black queen is on E5. You can move the rook to D5, checking the king with discovered check and another check from the rook and making it so that the king must move. Then, you can take the queen.

P.S. knights are also overpowered as they cannot be blocked and is also the best way to do a fork as no other piece can capture it if those pieces are on the knight attack squares.

These are good tactics everyone knows it I guess but in long run pp on the pp is best tactic

Double checks are so powerful as the king can only run (you can’t block a check from 2 pieces or capture 2 pieces), sometimes it’s worth sacrificing a queen just to setup the battery for a double check. This is well covered in the chess steps curriculum I do with my students.
