I have an issue with continuation bets, both making and playing against them. So I've been reading the poker blueprint chapter on the issue and I came across and interesting situation. Whilst the book uses exact cards for ease of explanation I think this could apply to many situations.
THIS SITUATION APPLIES 6MAX GAMES AND TO OPPONENTS WITH TAG LIKE CHARACTERISTICS: NOT MICRO-DONKEYS!!!!
Hero is CO and raises 3xbb with 7 
5 :heart:.
BU and SB fold
BB flat calls
Flop is J 
5 
2 
BB checks, Hero bets 2/3pot, BB raises to 3 times Hero's raise.
In this situation the book recommends either calling or 3betting. Explaining that in most games at the levels it has been written for the BB is unlikely to hold anything very dangerous. 22, 55 and JJ are likely to just call and hands such as AJ+ or QQ+ would usually have 3bet pre flop (bearing in mind this is against players that fall into something like a TAG category). I'm happy to trust this line, it seems logical (other opinions are available) and this is a situation that I have had trouble with prior to reading this.
However whilst this information has been useful to me what I also struggle with is a situation in which a fairly TAGish opponent playing OOP vs me leads with a bet. E.g.
Hero is CO and raises 3xbb with 7 5 :heart:.
BU and SB fold
BB flat calls
Flop is J 5 2
BB bets 2/3 pot, Hero????
How does leading rather than check raising give us different information about his hand?
Thanks
Hopey
