When you hit the stalemate cap of 953, play against a level 100 computer and use this clip and follow the moves exactly and you will 100% of the time get an 11 move checkmate for 1-2 points a game. The game lasts ~1 minute when you memorize the moves. Here is the clip

Using this method you should be able to get a rating of 996 (this number may vary for you, it may even be as low as 983) you cannot earn points on level 100 computers anymore. You will have to beat a level 1000 computer until you get to a 1000 rating. The chess solver I used was www.nextchessmove.com
A lot faster than doing ~15 level 1000 games.
