Why this move is weak ?

Hi, could someone explain me why e6 is considered much stronger that e5 ? After taking the bishop with pawn I would have never considered it.

Well, a lot of openings forsee two pawns on 5th rank, what's the difference here ? Better, why e6 is good, what is the plan behind that move ?

Thus, it could be ok if I captured the bishop with knight since castling king-side is safe ?

EDIT: for instance, the following seems ok ..

So, the "problem" should be the pawn structure on the king-side.

I don't know much either ..

I forgot to mention the last one was one mainline proposed by almost all engines. Nice fortress, but a bit blocked, that's why I preferred to take more risk.

The opening is known as Levitsky attack (1. d4 d5 2. Bg5).

AFAIK is quite unusual but I reckon white can play well. I found Anthony Miles played this attack.

But, as a reference game .. I would propose THIS one.

Thats a funny looking bishop unless its attacking something its not doing much of a purpose by just losing tempo if it gets shoed away

Top players would not have exchanged bishops ..

I don't know exactly the purpose of the attack .. but here is the idea of Wikipedia :-)

.. exerts an annoying influence where it pins Black's e-pawn and is ready to meet 2...Nf6 with 3.Bxf6, giving up the bishop pair in exchange for saddling Black with double pawns ..

That is exactly where I felt, explained in the 1st diagram why.

The f5 square is weak imagine white someday having a piece on f5.

Outpost for a Knight .. sounds good, for white.

How would you develop after this mistake ?

Well you forgot about this solid line 2...h6 3.Bh4 c6, where Black will play 4...Qb6 on the next move, attacking the b2-pawn and thus taking advantage of a drawback in White's system, namely its absence from defending the queenside.

what engine were you using?

I mainly use Hiarcs and Komodo

I don't say where the best lines, but playable at least.

hmm i would choose e5 over e6 in that position, engines are not everything, though of course neither am I.!!

Maybe I did it just because it's more easy on eye than e6.

By the way .. Tarrasch Toy, a lot weeker than the others, evalutes as good the move.
