Motiffs that makes tactical shots or Ways to decide if there’s tactics in the position.Look for:

Under defended pieces/pawns

Weak pieces or weak squares

Airy/unsafe king

Control of open files or diagonals

Queen, rook, king[any order] on same file,rank, or diagonal

Opportunities for knight forks or pins

Checks[even if they look silly]

Batteries[combinations of Q,R.B ON files,ranks, or diagonals]

Back rank weaknesses

Passed pawns on 6^th, 7^th, ranks

Positional advantages such contol of file or diagonal

Sacrificial possibilities around f2,g2,h2 or symmetical square
