Do you think its still applicable today? Im talking about leading turn out of position. I think its a lot harder controling the river like that these days cause there are much more smart players and with much more different style of play than it was back then

It will depend on diferent factors buddy,how manny streets thouse your hand has? is a scary card good to keap blufing and the most important one,how much your oponent fold the continue turn

Certainly poker action patterns are already very well-groomed. I am aware of this and I see a lot today that it is so much harder to play poker than today because today I am more advanced and so are the other players.

Times change and so do the moves! A lot of experience has already been shared, think about it!
