What your favorite chess openings?

My favorite is probably the Italian Four Knights Game as Black due to a really cool temporary knight sacrifice that leads to Black gaining control of the center:
1. e4 e5
2. Nf3 Nc6
3. Nc3 Nf6
4. Bc4 Nxe4
5. Nxe4 d5

the ruy lopez opening for white

the pertov defense for black

Grob

lets not forget the best gambit on earth, the one that will 100% beat magnus.
the intercontinental Ballistic Missile gambit.

I don't like any opening but I'm more comfortable with Spanish and Scotch (with white) and French and Russian (with black).

It depends on personal style more than anything else I think. Personally I like the move 1. Nf3 for white purely due to its flexibility. You can play systems like the Nimzo-Larsen attack in blitz, and in classical games you can transpose into strong openings like the Catalan, the English or even some of the mainline d4 lines

Personally, I really like the Petrov from white's perspective. Not sure why exactly.

Italian game (specifically the fried liver) as white

Caro and KID/Pirc as black

I truelly have a deep apritiation for the London system when playing as white
As black it will mostly depend on my apponenr i play the Carocan against e4 and the slave against d4
These opening might seem extremely passive but I belive as a more aggressive player that they are great for all levels players
Kindly note that openings do not matter as much as other game phases such as the middle and endgame

There is no favorite opening for me. My favorite is a triple layout formation. The aim is to create it while developing my pieces and before I castle. In other words the 3 golden rules is my favorite. The triple layout approach creates an opening family repertoire. My chess insight shows the King's pawn games are working in my favor. Has the highest percentage of wins. People can call their games what they want. I prefer trying to remember a pawn layout. If it has a name, so be it. Take a close look at the 2 or 3 pawn layouts and you might find a new approach to openings.

An opening needs 2 to 3 pawns to complete an opening. Before you call it your favorite opening, make sure both bishops can be move. I truly believe an opening is not complete before you can mobilize you pieces, like both bishops must be able to get out of bed.

Since the beginning of 2023 my present triple layout has been c3, d3 & e4. The order of the moves and the development of the pieces depends on the opponents responses to my moves. Some times it works and some times it doesn't. I like to put two knights on the same sector of the chessboard. When I was younger my favorite triple layout formation was a V with 3 pawns. Some call it the stonewall, others the Botvinnik system. and sometimes it's the fianchetto where the V is turned over like a roof top. The name changes because the V is not placed on the same squares of the chessboard. There are many triple layouts that don't have names. A triple layout pattern is probably a better term.

Each pawn has a role to play, so support them well. They are the reserve force that can become useful when you need more pieces to win. A player remains in their comfort zone when they succeed in always building their planned pattern. @cloak455

There are patterns in the opening, patterns in the middle game and obviously end game patterns too.
