After he played Bxf7, didn't you look at that position and say to yourself, "Where did that Bishop come from?" You obviously weren't concentrating on the game very well.
Not as easy as it sounds. I've had two OTB games where I missed my opponent's illegal moves. In one game, I was concentrating so much on my next move that I missed it. In the second game, something didn't look right, but I couldn't determine what was wrong, and the clock was ticking.
if yer dumnuf ta miss that then gitcher sef on back to checkers
How would you look at all my games? Most of my tournament games are on a scoresheet sitting on my desk and will never make it online.
This site has tournaments. I thought you were talking about a tournament on this site.

Yeah, well this thread is about overlooking things anyway. 
" I've had two OTB games where I missed my opponent's illegal moves. "
Pay Attention!
I think you're giving the wrong people that advice. 
It's good advice for everybody. I can't find it, but I saw a game where a GM overlooked the fact that his queen was hanging.
It's not an illegal move, but the root cause of missing an illegal move is not paying attention. Missing an illegal move or hanging a piece is still embarrassing (I can laugh about it now, but it wasn't funny at the time).
That's not ''illegal'', though.
HOw is it not illegal? It hopped over a pawn. Right?
this doesn't sound like a bad idea.
You choose your best move. Then, instead of making that move, you move the piece to somewhere iilegal but good for you.
If your opponent calls you on it, you say 'Oh, crap, sorry.' then move it to where you planned to anyway.

Troll or genuine?
Oh. and be sure to put on a good move when 'looking' for a place to put that piece you MUST mvoe now.
Good points, woton - you could understand if a player went for a drink or a walk later in the game, then came back and couldn't work out his opponent's last move, because it's not highlighted, as on here, and your opponent doesn't have to tell you it - however, this was move 8, most players would be at the board, and he's had f7 covered by the d pawn for a few moves, and one of the reasons he played ...Re8 was because he knew he had it covered - or should have!
If I remember well, there was a Sajtar vs. Simagin game where one of the players answered a check with another one, so both kings were under check the next move. It was the public who noticed it at the mural board...
When I was a kid (about 8 or 9 years old), I often played another kid around my age, and he constantly attempted to cheat. For example, he would move his king two spaces; when I pointed out the illegal move, he would argue that the king had started in a different square. I started recording the moves of the game even though these were supposed to be "friendly" games so i could reproduce a position and show him that he was wrong. Of course, he would insist that I had written down the moves incorrectly.
Sometimes, he would go so far as to jump a bishop over a pawn and argue that this was a legitimate move. Of course, when I tried to do the same thing (i.e., jump my bishop over a pawn), he would object. When I pointed out that he had done exactly the same thing 3 moves back, he would come up with an explanation that the bishop could jump a pawn only if the other player had made some sequence of moves (e.g., if the opponent had castled or had moved his knight).
I let him cheat, but I still beat him most of time. I'm not sure why I continued to play him even though he cheated. Maybe it was because there were few kids my age that played chess or even knew how the pieces moved.
Ironically, once when I captured his pawn en passant, he insisted that I was "making up a rule" and was cheating. There was no internet back in that time, and I generally did not carry a copy of the rules of chess with me. So I conceded the argument and took back the move even though I knew I was right. He then went around the school to all my friends declaring that I was a cheater and made up "fake" chess rules!

Online chess generally won't allow you to make an illegal move - the software interface just won't let you.
It must be a much greater risk in OTB Blitz games, where time is at a super premium - does a person making an illegal move in such a tournament automatically lose that game?
I guess this is also one of the main reasons why both players are meant to record the moves being made - makes going back one move to verify a lot easier.
3...c6
Is that theory? Seems weird.
It's probably a glitch. I've had several glitches on this site. One where I had no dark squared bishop, one where I was missing a pawn. I think you are going overboard with your assumptions here and calling a random stranger a scumbag when you don't really have the full story.

guys remember, this happened in a real life tournament. I wouldn't care if it was an online game.
and yes, 3...c6 isn't the main move, but it actually tranposes to a known version of the Petrov. Ng5 is the strange move, with d3 being played almost exclusively at the top level.
The funniest thing is that you typed !! after Bxf7, like Oh my God that really was a great move!
