White Openings

Start with e4, develop your knights and bishops, castle. The Italian (1.e4 e5 2.Nf3 Nc6 3.Bc4)is a good option since it allows you to follow these opening principles.

They said that it  depends on your playing style.... If you have the such one. )

It means that you should choose the openning where you will be feeling yourself comfortable during the beginning of a game.

Some like open positions... others like very closed ones.

Many recomend for novices in Chess... London System.

Colle system, simple yet can be very deadly

The entire point is that you're going to plop the knight on e5, and play moves like nbd2 -> ndf3 + f4 and go crazy on the kingside

There is no "best" opening.  And at your level openings are the last thing you should be studying.

))

And the first and crucial thing for you...  to not keep blundering in every game.

I don't understand how can he move his Knight onto e5 ?

Fianchetto supports the Knight jump

Thanks you guys!

Chess Openings Tier Lists by GM Hikaru Nakamura and IM Levy Rozman

Chess openings are rated in terms of their appropriateness vis-a-vis player skill level - i.e., beginner vs intermediate vs GM’s, etc. They frequently refer to some openings as "garbage" or "bad" (an unfortunate choice of terms).  However, these qualifiers are meant to convey how appropriate the specific opening is for the level of player being discussed, in terms of, for example, how much so-called "theory" (i.e., documented variations) the opening encompasses, or how much emphasis the opening places on positional versus tactical skills in order to play it well.

So, an opening they refer to as "garbage" for a beginner may in fact be appropriate for higher rated players who typically know more of the theory for particular openings and have a more highly developed understanding of positional concepts. For each of the openings discussed be sure, also, to pay attention to whether the evaluation is from White’s or Black’s perspective...

Queen's Gambit

Thanks

Bishops opening its fundamental and catches many by surprise 

Don't worry too much about openings just try to develop your pieces and castle as soon as possible. I would suggest though to start the game with e4 as white because you can generally develop an attack much faster.

play whatever you think is the best opening

Their is no "best" opening.  You find openings that give you comfortable/playable middle games.

I like the London System, really easy to learn, solid
