Not sure about this version of live blackjack, just introduced by Playtech. The majority (player) vote dictates the play. If there are less than 3 players at the seat, basic strategy is employed by the dealer (probably the better outcome). Either way, the decision to Hit, Stand, Split or DoubleDown is never in your hands alone. More at https://www.livedealer.org/blog/2020/06/majority-vote-or-best-strategy-blackjack/
