25PLO
sorry no HH, just memory
hero dealt Kd6d4x4x

Several limpers, I'm MP3.

flop Qd4d8d

I bet Pot, got 1 call, and turn was a non-pairing Diamond.

Should I be firing? Getting as much money in as possible, or taking it a little slow.

Effective stacks were villain with ~15, and me with ~25

The hand is junk - fold it pre-flop.
Since opponent just called, maybe he has low flush or set. Fire again.

Also position of opponent to you is fairly important. Remember things accurately, and better advice can be given...
