I only have HoH volumes that I've read long time ago and got out tons of useful info, those series are pretty incredible.

I haven't played MTT lately and I want to start playing 5 - 20 (or higher, depends on action) dollar buy in MTT online. Should I go back to Harrington's books and call it a day or there is a better book that will cover modern tourney play? There's gotta be one right? I know "Easy Game" blew my mind for online cash games, so I'd love to find something like this for MTT.

Moorman's Book of Poker is pretty good I think.

Kill Everyone and the Raiser's Edge are quite good imho, even if 100% of them is not strictly applicable there's still a myriad of valuable information in there

Winning poker tournaments one hand at a time.

Reading it currently, 1st book of the series. Been learning stack size considerations at advanced level. Even the play of the hands is advanced level.

The bluff range preflop isnt there as it should possibly these days be and the gto way isnt there for the same reason but hands are generally well reasoned.

I skipped rizens hands for now because i wasnt exactly happy to his 1st 10 hands analyzed as far as i view and play the game but been overall happy, learning stack size stuffs and read good reasonings, even if i dont think or even play exactly that way. But been taking my time with most hands and the analyses are good.

I dont think there are any modern ranges in any tourney book yet even if the book is new. And adding cash ranges in, it isnt that simple mostly but not only because of stack size considerations.

Pot control ideas are here also many times, but not sure if thats correct but when expecting the other to be more passive or when one would pot control in cash games also, or there are weaker players. But i dont yet see what mtt are compared to cash games additionally to stack size and bubble and final table and weak players vs marginal hands i suppose.

If you read Harrington's original series already, those two are a very nice (and important) complement!
Adjust reshove stacks etc. to curent min-raising tendencies and there you go.

NB: Remember though, in today's game, reading 4 or 5 books is a very good thing already, especially if you're good at applying the concepts and adapting, but unless you're really good, it's not going to be enough to crush the tables as you could have, like 6-7 years ago.

As above - Harringtons books, Kill Everyone, Raisers Edge and watch some of the modern players on youtube - assisanato has a few free vids on youtube which are amazing and give you an insight into a great poker mind.

Should also add - watch Tonkaaaa when he is live on twitch. He explains his thought processes whilst playing and plays a wide range of buy ins from medium to high stakes.
