So, I just played the following game:

Morphy - Count Isouard/Duke of Brunswick

u shudnt feel gilty ur opponent decided to follow a famous game, and u played the best moves(which i guess were stored in ur head like they r in mine)

 We have a winner! That is indeed the game. I couldn't quite believe what was happening, I had watched the game on a Youtube video only last week. I kept thinking, is this guy just following the opening explorer without looking at the result? Then he just blundered when it was too late and it was mate.

=) good job to remember what u learnt in a video =)

 Cheers! Although, as kid_of_chess said, it's one of those games that sticks in your head, and I checked the database to see I wasn't doing anything stupid. I think 10. Nxb5 is a bit of a risk, but hell, if it's good enough for Morphy...

 Qoute of the Day!

(I hope I got the source right)

 ...That one's for free :)

I think it's actually considered to be principled and sound...

That must have been so much fun.  Great job Deeds!

Repeating games is far from unheard of in chess, even at the GM level.

I bet that was your friend and you guys did this on purpose..

I had a friend once.....once.

 me too.. once... sighs... :(

 Nope, just a slavish follower of the opening book, apparently.

I wouldn't call it cheating. You are allowed to follow a set opening, aren't you? This game is so famous that all chess players should know to avoid it.

It does raise the question with me as to why anyone plays the Philidor defense. I've had a look at the stats:

White: 45.3% Draw: 28.2% Black: 26.5%. My own stats are even better. White seems to be doing very well after only four or five moves. Is this a bad opening, or are there hidden depths to it?

I have played it occasionally when I'm fairly sure the opposition will play 3 d4 allowing 3 .... f5 (Philidor's Counter gambit) but got murdered by a move that didn't feature in any database after only 5 moves last time I played it. I'm probably going to retire the Philidor from my repertoire after that mugging by a lower rated player.

hehe...i cant believe that there also have cheathers...

 I think those figures are a pretty good indication that the opening is weak.

The Philidor is a principled opening; however, it is also used by lots of beginners who probably don't even know the name of the defense they're playing. But I suspect that is why it doesn't score so well.

3. ..Bg4? is such a typical beginner's mistake.
