Ok fair enough, you go with the 2+2 standard defens, cheackraise to charge the mximum when you are ahead.

But then my first question comes up again. Why does HFAP recomend that you must bet out alot to "preserv this higly profitable play".

There are 2 ways this could have an explination. Either Sklansky and Malmuth was wrong or the play works alot better against the players they are used to. The later is the case in the loose section of the book.
So against what type of player is it correct to bet out and
witch typ is correct to cheackraise?
