Good move? Bad move? Am I mental?

[PokerBarney]

A hand which caused a lot of action in the chatbox at the time. I figured i had 15 outs (spades, kings and fours), and that villain may be betting on draws or TPNK and would fold.

Re: Good move? Bad move? Am I mental? Too over aggressive for me, as despite your outs in essence you are all in on a (semi-?)bluff, but as short stack and with an M of less than 10 (after paying your ante) then I can understand your play if your intention was to take the pot there. I'm guessing small blind had trips or a straight, and you caught a spade on the river?
