Bad call?

[gjpure]

Was playing 200 max NL live in the casino this past Tuesday. A new table just started, so we all sat down at the same time with the same amount of chips. Right away it became obvious that there was this super agressive bully type who was cleary controlling the table and not afraid to reload if he lost. Anyway, I was folding mostly for the first hour, trying to stay the heck out of the way of this maniac, but at the same time observing and trying to get a feel for him and everyone else. Well a hand comes where he raises in EP and I call in the blind with AJ off. The flop comes with a K and all spades. I hold the A of spades and am first to act. The pot is about $50 and I am first to act and I bet $30, hoping to take it right there, which I was able to do to him once before. Well, he moves AI for $180 total, which he had been doing several times to people. I know he could have anything, but likely only has a K. I am confident that a spade or an A will win me the pot. Now, I am terrible at calculating my odds in a spot like this, but this is a common scenario. Now, if this was anyone else I probally would have just checked, or bet and folded to his AI. But since it was him, I called and said "I am only calling cause it it you." Turned out he had something like K9 and won the pot. Later, I rebought and walked away with over $500, but that one particular pot was one of my few bad decisions of the session and I justified it because of the type of player he was. What were my odds to win the pot assuming that I was "pretty confident" that a spade or A would win? Also, with all things considered was is a good call? In other words, might it send the message to not go AI on me again, or would that only send that signal if I won the pot? I wasnt afraid to play with him, but at the same time he was an agressive player who knew how to play. IF I would have just checked and he bet, I would have just folded. Obviously my pot odds were also terrible, but when I put it all together I "felt" a call was appropriate at that point. Thoughts?
