3-bet pre-flop or check-raise the flop?

[kiddo]

As I said earlier Im not an expert at hu. But today I tried playing like this, always call in BB and checkraise flop if I liked it. I played 3-4 hours at $5/10 and $10/20 and the guys I played against was poor but I noticed a few things:

1) Its much easier to play this way, u dont have to think until he does something on flop. U dont have to mix it up preflop and on flop.

2) Since u always play the same way its pretty easy to detect patterns in your opponents play (at least against the players I played), you always do the same and now its up to them to get a good mix of valuebetting/bluffs/slowplays on flop.

3) Bad players almost always call when u flopcheckraise them, no matter what hand they got, but if u 3bet preflop they will fold flop if they got nothing, so u often get 2 bets from them on flop when they got 3 outs or less. (This made me start to 3bet some of the weaker hands of my normal 3betting range, like KJ or small pocketp.)

4) When they see that u never raise preflop and never bet flop the once I played tried to counter that which made it easier to read them (cause they did it so clumsy) and made them play less then optimal (if they had seen my hands).

Im still not convinced its a good way to play against all type of players and against players very good at adapting. But I really dont know.
