Preflop: Hero is UTG1 with K:c, K:s.
Hero raises to $0.40, UTG2 calls $0.40, 2 folds, MP3 calls $0.40, CO folds, BU calls $0.40, 2 folds.

Flop: ($1.75) A:s, J:c, 6:h (4 players)
Hero checks, UTG2 checks, MP3 bets $1.75, BU folds, Hero folds, UTG2 folds, MP3 gets uncalled bet back.

Final Pot: $1.75.

The first caller is an unknown (17 hands), MP3 seems to be on the looser side , 3rd caller is also an unknown.

With that flop and 3 callers should i be pushing or is my check/fold correct?
