Guide to learning professional Chess!

Learning Chess on a professional level:​

Hello everybody!
Today I'll teach you how to play, learn chess (No, not on a hobby level).​

Requirements to practice:
~ An experienced player to practice against
~ A chess program
~ Time
~ Internet to learn moves and combinations
​

Step 1):
Opening books:
What is an opening book?
Opening book means the first 5-10 steps of a chess game, depending on how your opponent reacts, there are some plays where people do "strange" moves to bring you out of your playbook quick.
Opening book means that if e.g. someone opens e4 as a beggining, you should either react with a e5,e6 or c5 move.
When you've played around 100-300 serious chess games, your opening book may even involve the first 10 STEPS! (this means you will know what to answer without thinking!)
Step 2):
Combination:

This is a very complicated step series. This means that it's black turn and he will move his Rook to the spot shown with the cirle. After that The black mark shows that the white knight can NOT move anywhere, so he SHOULD indeed move his king to the spot shown. After that the black knight will take the white knight out and the game can go on without recieveng a checkmate. IF he wasn't to move the king it would make it A LOT easier for black to give white a checkmate. To be honest the best way to learn serious check is practice on the internet, read famous games and download programs to practice with. I started playing chess seriously about a year ago and I've already had good finishes in real chess tournaments.
Hope I helped anything at all.​
