Thanks for the recommendation! I will use it after pandemic ones live poker is back

in the online world I believe it works fine. Isn’t it?
The thing about slowplaying is that sometimes you get your opponent a chance to beat you. This kind of slowplay also depends on position.
For example, if you are in small blind, it is technically the worst position, but since you are first to speak, if you check, and there are 3 people left to act after you, you are now in the "best" relative position, you'll get to see who raises, who calls, and who folds, etc.
If your opponents don't show strength, then you can go and bet, because you might have good enough fold
equity from them, and steal the pot right away.
Definitely mix aggression with slowplay, that way you are not predictable. As long as you have a read on your opponent, and this strategy is working out for you, I'd say you can keep going.
