I believe all players at the table, must ante up a pre-determined amount (be it $1,$2,$5 or even $10 per person), before the cards are dealt.
Then I think there is no action until after the flop. So all players get to see a flop, with the hands they are dealt. The pot starts off with a nice “bomb” and can certainly grow pretty dam big after just one round of betting. I have had losing nights turn to gold because of just one “bomb pot” victory.
