1. Chess -if you want to last more moves against a grandmaster
This assumes you know the rules and you are playing white.
Most books recommend you play "1.e4" (moving the pawn in front of the king two space) if you are a beginner.
But if you want to last as many moves as possible against a stronger player (you won't win if they are much better but they can get frustrated if you give them no opportunities to win) , do this.
The London System:
Your first moves (almost no matter what black does), should be:
1. d4 ... 2. Bf4....3.e3 ... 4. c3.... 5.h3.... 6.Nf3.... 7.Be2.... 8. O-O ... 9. c3... 10. Nbd2.... 11. Re1....

Ideas:
- Your dark squared bishop is not stuck behind the dark pawns
- you do h3 to retreat your bishop to h2 if they ever do Nh5.
- if they do Bd6 (offering a trade of bishops) then take the bishop . Now you got rid of your bad bishop.
- c3-d4-e3 makes a solid triangle that is hard to break with ...c5 or ...e5 (let them trade if they do one of those two moves)
- after Re1, if you can do it without losing a pawn, do 12. e4. Your entire goal this opening is to do e4.
- your king is super safe.
Watch a video about the London system to get more ideas.
And, of course, these moves above are guidelines depending on what they do but often they will let you do these exact moves.
This is considered passive opening but every great player occasionally plays it so it can't be that bad. It's considered super solid.
the problem with 1.e4 is that things can go crazy really fast if you don't know what you are doing.
