reconiqze the patern vs can't be remember the pattern


I think tactics are supposed to help your calculation skills, not to get you to remember every single move of a particular problem

how do master play very fast in bullet,exp,I had study such a sicilian opening and a lot of theory,if it repertoire it hard to recognize ,and how do they play fast,

dragon is different pattern ,nadjorf is different patern,I mean that I had some problem to bring equal position if it repertoire,mostly I played nadjorf,shevningen,with 1500 to 1700 ,if they played close or adam then I can't remember the pattern,mostly high level play,how

Actually, that's how masters learn dozens of moves of theory in the sicillian. After a while, you learn that the Nadorf, dragon, sheveningen etc.) are all very similar and you learn how they can transpose. But not too similar! You learn the differences between each one and how to not get checkmated before move 20.
