How to beat strong computer

I made draw with 1800 rated computer ( today I play aganist computer some days ( I played very very fast , I made one mistake xD winning position ... )

2000 elo computers don't use books ( normally )
( some chess websites (not lichess or 2700chess) ) 2000 rated computers made wrong moves in opening ( not middlegame or endgame generally )

ıf your elo ( online ) U1800 you need study a lot (learn some tactics after read books) to beat 2000 elo computer ( I think chess27000 elo overrated and U2000 elo computer is very weak ( play on chess.com or lichess )
my second account : sajdragon0 ( I don't play chess games on this account )

The only way to beat/draw a strong engine is to use another engine.
Give it more juice, and see what it plays, note the move.
Play the game again, try to follow the same lines.

After enough games, you no longer need the cheating engine as you will know the replies.

Now play the game, post in the forum and claim hey 'I' drew/defeated this very strong engine!

@BlackSalt you can beat engine ( time out etc. ) example Leela chess

What exactly are you claiming?
Is it that you can hold out without directly or indirectly using another engine, and you can do it at such a speed that you can time out a strong engine?
