Hi, i am a casual player playing on partypoker 25NL

The hands i have the most problem with is when i limp in with couple players and i flopped top pair but with a very low kicker <9.

If i am holding Ax, Kx, Qx, i normally just test and bet half the pot. cause i know in partypoker people loves to play high face cards with any kicker, so i don't know if my hand is good or not at this pt. Is my bet right ? i would love to hear what would you guys do in this sitiuation.

and what happen if u get a call? do i keep leading or check turn or river?

thanks in advance!!
