Best opening?

KIA

Well we all know engine says e4 , however one time I was playing one guy for money OTB FM with a rating of 2300+ ( I didn't know his rating or title before game started ,other ways I wouldn't even think about it playing lol) and he played his first move as white , which was D4.

Some other time I was playing another guy OTB also for money GM with a rating of 2600+ ( same thing here didn't know who I was playing other ways I would run away lmao) and he played his first move as white D4 !

The bottom of the line is, I'm not saying it's a best opening, but two random high rated players with a title played that opening especially playing for $ says alot.

king pawn opening, like too by Robert James Fischer

queens gambit. and at your rating you'll win a lot because >1000 won't know about it and 9/10 times they'll take on c4 and attempt to cling on to the pawn in which case you'll win.

 Italian opening giuoco piano is a good opening and it is always less slow of how much black player thinks.It has a bit of poison.

www.365chess.com Opening Explorer.

The February 2017 issue of Chess lists the top twenty openings compiled from a list of 4561 December games where both players were rated over 2400 Elo. One can not take position on this list too seriously because it is greatly influenced by how the openings are grouped. For example, all the Retis are grouped together, while English is separated into 1...c5, 1...e5, etc. Nevertheless, for what it is worth, some of the list entries are: 336 Retis, 198 King's Indians, 186 Caro-Kanns, 159 declined Queen's Gambits, 158 Nimzo-Indians, 148 Najdorf Sicilians, 135 Slavs, 128 1...c5 Englishes, 114 Kan Sicilians, 102 Italians, 98 1...Nf6 Englishes, 97 Queen's Indians, 88 1...e5 Englishes, and 78 Berlin Ruy Lopezes
"... anyone who is just starting out should not dive into the vast ocean of theory that is the Najdorf. For beginners, the time invested in studying even minor lines can be more productively used solving tactical puzzles and basic endgame technique.
For someone seeking help with choosing openings, I usually bring up Openings for Amateurs by Pete Tamburro (2014).

I believe that it is possible to see a fair portion of the beginning of Tamburro's book by going to the Mongoose Press site.

Perhaps AlvinDaniel would also want to look at Discovering Chess Openings by GM John Emms (2006).

"Each player should choose an opening that attracts him. Some players are looking for a gambit as White, others for Black gambits. Many players that are starting out (or have bad memories) want to avoid mainstream systems, others want dynamic openings, and others want calm positional pathways. It’s all about personal taste and personal need.
For example, if you feel you’re poor at tactics you can choose a quiet positional opening (trying to hide from your weakness and just play chess), or seek more dynamic openings that engender lots of tactics and sacrifices (this might lead to more losses but, over time, will improve your tactical skills and make you stronger)." - IM Jeremy Silman (January 28, 2016)

I've recently liked the scotch. It has a nice taste to it as well.

If its not from Scotland it cant be called scotch. Whisky fact.
