X ray vision

Sometimes, I feel like I have X ray vision at the poker table. Sometimes I can "see" what cards my opponents have by the way they're betting. You'd think that would be helpful, right? As it turns out, it's only as helpful as your knowledge of poker odds is good :-) In the second tournament I entered last night, I got to heads up, but only lasted a single heads up hand. My X ray vision correctly told me what my opponent had, but my gut feel for the odds of the situation was way off. Here's what went down:

Table '632163287 1' 6-max Seat #5 is the button
Seat 4: neostreet (1185 in chips)
Seat 5: (4815 in chips)
Seat 5: posts small blind 100
neostreet: posts big blind 200
*** HOLE CARDS ***
Dealt to neostreet [Qh Kc]
Seat 5: calls 100
neostreet: raises 200 to 400
Seat 5: calls 200
*** FLOP *** [7c 9h 3c]
neostreet: bets 200
Seat 5: raises 800 to 1000
neostreet: calls 585 and is all-in
Uncalled bet (215) returned to Seat 5
*** TURN *** [7c 9h 3c] [8d]
*** RIVER *** [7c 9h 3c 8d] [4d]
*** SHOW DOWN ***
neostreet: shows [Qh Kc] (high card King)
Seat 5: shows [5d As] (high card Ace)
Seat 5 collected 2370 from pot
neostreet finished the tournament in 2nd place and received 105000.00.
Seat 5 wins the tournament and receives 195000.00 - congratulations!

My X ray vision told me that my opponent had an ace and a low card. I knew that if he paired his low card and I paired either of my cards, I had him beat. I really liked the fact that I had two overcards to the board. I thought odds-wise I was just a small dog, and that it was worth it to call. As it turns out, I was a big dog, and never should have called. It would certainly behoove me to start committing the odds of certain hand matchups to memory.
