When is a blunder not a blunder

So I just won a 7 move game and it marked 3 blunders and 1 mistake out of 7 moves. However, I played a pretty meticulous game from start to finish, pigeon holing the king with my queen and bishop and baiting him to take my rook with his knight. As far I can see there was no mistake/blunder, so what exactly is it catching?

If you cant figure out why, then i can understand why youre a sub 1100 player.

my point is if the game went as planned then it's not really a blunder

So your "plan" was to hang material, and "hope" your opponent didn't see it?

Thats not a good road to improvement.  Thats called hope chess, and its a terrible way t learn.

fair enough.

If he catches it fine.  If they don't see it the game probably would have ended quick anyway,

I see your point. I didn't notice so wasn't paying full attention I guess. I had basically just picked a path and started moving the pieces independent of his actions.

No worries.  At some point, we all forget that chess is a 2 player game.  Like i posted earlier.  What you were playing was "hope chess"  You hope your opponent wont see the bets move, or a better move.  Again...its a horrible way to try and improve.  Good luck to you!

A blunder is not a blunder if your opponent also makes a blunder and thus rendering the game's balance to equilibrium.       

A blunder is a blunder. Depending on how hard is to see the blunder or/and on your opponent's skill you can get away with it but that doesn't take away the fact that you could have been winning by more on that you might have ended up losing. At the end of the day, don't worry cause we all mess up and even at my rank (which is not very high) I still blunder probably once a game

I agree. Maintaining the lead is crucial.   

Apart from the jokes, I agree. Blunder is a blunder because knowing it and learning from it helps you improve and prepares you to not make the similar mistake in future against a stronger opponent who can exploit it unlike the one who couldn’t. You won because you were lucky and your opponent failed to exploit your blunder and failed to formulate the best possible course of moves in response.                

It is good that you went over your game and found your mistakes. This is a path toward improving.

Yup. I get you guys. I actually just didn't notice in this game. When I pay attention I'm capable of putting on a good game on occasion depending who I'm against. I have weird losses and wins. Some 98% accuracy games and even to this day occasionally losing to a fool's mate. It's probably because I'm usually doing an assignment or watching a movie while playing or something. Ironically, it also looks like my opponent was thinking the same as me. He was so confident he could take that castle he didn't even notice my queen. It's like arrogance lost the battle.

I guess that answers the question. A blunder occurs literally when you aren't paying attention.

So on that end if it is foolish to plan ahead without considering the opponents response and hoping the opponent simply doesn't notice, then who is the Fool in the Fool's Mate?

It's more of a blunder which is countered with an even greater blunder.

Even within the "blunder" category, some blunders are greater than others.

Maybe the second one is even more fitting for the "some blunders are greater than others" tag.

Don't blame yourself. Sometimes backward moves are hard to spot because the general direction of movement and attacking is the forward direction.
