Rosen Score

I have just rediscovered this super fun website. Rosen score keeps track of many unusual achievements in your chess games. 

Just enter your username at rosen-score.vercell.app and it will generate your "rosen score" - the total number of Eric Rosen style goals you have completed. In the process you will be reminded about some of the most interesting moments from your games on chess.com. 

For example; I learned that I have scholar's mated not one, not two, but three titled players -

... and that I have executed 24 sucessful lefongs

... and 24 adoptions, which pales in comparison to Hikaru's 500+ adoptions.

Some of my favourite goals are related to dirty flagging. The site will tell you how many times you flagged an opponent who had mate in 1, as well as how many times you won with a single pawn whilst down 10+ points of material.

It will also tell you how many times (if any) you've had quadrupled pawns in your games. I was surprised to see that I've only had this once, but it seems like I am lucky to have got it at all, as they may appear in as little as 1 out of every 90,000+ chess games.

Luckily there is no achievement for quintupled pawns, which only occurred twice out of ~1.9 billion games.

Eric Rosen has 61 out of 62 possible goals, only missing an elusive 4 knight-cube checkmate (whatever that means).

I have only completed 40% of the total goals, some of which are so ridiculous that it would be impossible to get them in a game unless you were trying for them (such as playing the headache opening).

Overall I have 540 Rosen trophies, but almost half of them come from getting stalemated in a losing position. This has happened 215 times in total, including 21 uses of the famous Rosen trap. Some well-known victims on these lists.
