Practise, study, review your games... So much, so obvious.
But I also recommended a book as a good
Ray Cheng, Practical Chess Exercises
It offers you 600 positions (in sets of 8) for 'solving', so one of them will be a snap mate in 2... but among the others we might find something that looks like a mate in 2 but will fail because of some horrible smelly trap, or a delicate endgame finesse, or a promising attacking position where the best move is actually to win a pawn, or a position where the 'solution' is to avoid a haymaker coming your way, or a deeper tactic that takes a deal of head-scratching, or a positional coup... The exercises are graded in difficulty from one to four, and most sets include one at each level. I guess this as close to practical play as a book can get: you are faced with a variety of challenges, some straightforward, but some rather less so; sometimes you enjoy the chance to attack, at other times you have to defend, and you'll never know what's coming.
Nunn's Chess Puzzle Book also gives 250 mixed positions (which I
can guess are tougher) but it seems to be out of print at the moment.
