On GTA 5 Online, Beach AW is a type pvp in which players use "All Weapons" to kill each other. The purpose of that is to kek (spawn-trap) your opponent.
Most Beach AW players are tryhards so you can chose the easy way out as much as you want during a fair 1vs1.
The other rules are : you can use every weapons except the special rounds on the heavy sniper mk2, no vehicles, no ceo, no off radar, no BST, no RC Bandito, no lamar, no friend helping you, no Orbital canon, and you can spam explosives.
Giving up in a 1vs1 Beach AW will automatically make you lose, whatever the score.
