This is my second hand at the table and I have no real reads, however the first hand I did see mp2 over bet the pot on the river during the last hand on a total bluff.. no busted draw or anything, no idea what they were doing in the pot at all.

So, should I be considering folding this flop? I re-raise on the flop because I want to push out KQ or a flush draw, AJ can also go broke here too.........
so anyway, by the time it comes back to me I have to call $6 to win $40 pot..... so how is my play here?

Should I call this flop bet? Should I have just checked preflop? No reads, but he is probably a donk, they all are. AJ is possible, guess KQ is too? I'm getting 3-1 to call with 2 cards to come but at best I am 3.14 -1 to catch and I could be drawing even worse than that.
