lichess.org/analysis Why on the first move 1.c4???
It does not matter. The initial position with 32 men has too many possibilities so the engine cannot evaluate properly because of the horizon effect.
@MUMAnshul130105 it shows d4 for me.
Also: Turn on 5 suggestions then it suggests all three moves (c4, d4 and Nf3)
The five best moves that Stockfish 11 suggests are mainly
(1) 1. e4 - King’s Pawn Game
(2) 1. d4 - Queen’s Pawn Game
(3) 1. e3 - Van’t Krujis Opening
(4) 1. Nf3 - Reti Opening
(5) 1. c4 - English Opening
There are 20 different moves that White can play on their first move.
