E4 - course by Ori

6 main moves to reply by black

E4 - e5 - Topic #1

black takes an approach of controling the center

* e5 can lead to 2 main openings - Italian game or ruy lopez

f7 square is a major weakness (Italian game)

Ruy lopez - best reply is a6 (main variation - Nf6 ((berlin wall)) is very complicated

+++watch for poison pawns+++

e5 and c5 are not playable (too late)
