is this angle shoot inappropriate?

im in a small stakes MTT home game. i only know the host who was not at my table.

3 to the flop. im in the SB:
checked to the LP who makes a stab. i think he's weak and i have 4 to the str8 and want to see another card or 2. im worried about the player in between b/c though he never raises, he calls with any piece or draw if there is no one acting strongly. anyway, i hold my call in one hand and a stack of chips in the other, i say "call and raise $2k". they inform me that i can only call since i announce call. this is what im hoping for.
the turn doesnt help me so i check, hoping they think i intend to check raise. it checks around. the river doesnt help me so i make a bet that looks like i want a call. they fold.

is this immoral, unethical or just plain uncool in anyway?

seems ok to me.

i dont think i really want a discussion of whether i could have raised or just called instead of this angle play. i'm leaving out alot for the sake of brevity.

thanks.
