My lower rated opponent is playing really accurately. How do I win?

I agree with TheChessKid90 because when you come up with a long term plan , you should be able to do it and win. Now if there is no weaknesses to exploit then think harder because there is bound to be at least one weakness your opponent has. No one is that good yet. USE THE WEAKNESSES TO YOUR ADVANTAGE. So, Find your opponent's weakness/es make a Long Term Plan then exploit the weakness so the opponent would have to protect it. Simple as that! AND DO NOT RESIGN. All about Lessons.

but it would be funny

agreed

It would be funny but no one will do it

i would

I think that the best strategy is to play an aggressive opening and get into sharp, tactical positions. The games you should sort of neutralized and turned into a positional battle. Maybe try to play more attacking moves early on, and catch people off guard. I am around your opponents' ratings and I find it difficult to defend against higher rateds who are better than me at tactics.

1600 players can play accurately, get used to them having good games.  Being 200 points higher means you will win the majority, but you will get your butt handed to you once in a while.  I think you are hoping people will tell you they are cheating, but nope, you just lost or drew.  Happens to everyone, even Carlsen.  Once you see your opponent digging in and fighting, you have to do the same. 

Best answer of the lot.

Who In the world would do that if you can still beat them

You can't make them falter but you can create difficult problems for them to solve. If you easily see how to solve the problem you've created for them - so will they

Agreed with the NM above, and I would say play for imbalances. Weaker players are usually worse at playing with imbalances and understanding the nuances. At 1600, you probably have a better understanding of pawn structures and endgames than players rated 200 points lower. Tactics can be risky to rely on since those are what weaker players use to try to catch out stronger players. When I was 1500 OTB I had a memorable loss to an 1100 on a bad day where I got smashed playing the Sicilian. I played him in a later game in the Philidor and he willingly traded rooks into a simple pawn endgame that was lost (outside passed pawn + fox in the chicken coop).

oh yeah i know that one its in a endgame book

My opponent didn't! Lol.

Silman's Complete Endgame Course if anyone is interested in which one. 

I checked 2 games quickly without much analyses and it appears that author had good winning chances with b-passing pawn in a first game. I don't know why he/she didn't take this chance and settled for a draw. 

The second game there was a strategical mistake to trade queens and pieces. If you don't want to draw and you are playing for the win stick to keeping queen on a board. 

In general: there is less tactical mistakes when the time control like that. It is expected that players above 1600 might not to do any blinders during the game. 

Also there was a blinder on your part on the move 56 - you should have moved the pawn f3-f2 with good drawing chances.

then she would have simply taken the pawn. I couldn't take her rook becuase then she would queen

I would say that play aggresive openings so that the opponent doesn't know what you are doing and make a short plan like go with the Evans Gambit Ready to do Ng5 and Qb3 to attack the f7 pawn and attack the King soon leading to a Checkmate.!!!!!!!!!!!!!!!!! 

thats cheatum.
