Thank you everybody, i really appreciated your help. Cardschat is really a nice place as some of you said in my presentation.
So i decided i will read, after professional no limit holdem, gaine's poker maths that matters, and i will check how is for me and expecially if i can actually apply what i learned when sitted at the table. If i decide to go further, i will for sure read chen's book, but as i saw in the reviews is about limits and derivatives and really complicated stuff, no doubt it is complete, but i dont think i can apply, at least by now. I will keep in consideration anyway, i think is a really good next step to go on, even if quoting punctual, i think math has importance, but secondary to the gameplay learning since big part of the hands doesnt even get to showdown.
Is anyway a book i didnt know the existence and now i consider a really good choice for an advanced players.
Thank you again everyone
