I have been playing with these guys for only past 3 days and as per my brief understanding i find them to be terrible players and huge fishes. None of these guys have a basic understanding of the game and mostly they play to get lucky.(Its good money though)

I have 2 questions.

1)Is my preflop call correct?

2) what should be my play on the flop.

The table has a minimum buy-in of 20BB.
