Colombian Poker Strategy

[jck8]

game in Barranquilla played exactly like 10 handed no-limit holdem expect everyone antes $10 per hand (no blinds), and the person who bet first the previous round bets first next round.

the buy in is $400 and the game plays wild. 50% of the time everyone will see the flop for free, the other 50% someone will bet $75-$150 and 2-4 people will call. on virtually everyhand one or two players are all in before the river card, then they rebuy and the game goes on.

the small buy in (relative to the antes), and the players affinity for gambling makes the game pretty wild.

my primary question is:

how should i play this game preflop?
