Thanks for commenting. Your solution is also correct, but I choose this one, as it is impossible to put two solutions, I put this one because it may be harder to find.
Then it's a good idea to mention that there's another solution in the puzzle itself...so people don't start clamoring that there's a cook.
Live Blitz 2084 (89 games, almost all of which were played from my cell phone while eating)
Live Standard 1842 (173 games, most played simultaneously with other games, or while cooking and/or eating. I've encountered a few cheaters in Live Standard as well)
Live Bullet 1869 (I'm really bad at 1min - but could probably break 2000 if I played a little more. 76 games)
Online Chess 2062 (I dropped over 100 points to a few bad days where I was dropping stuff left and right, that's the pain with 3day-move. 270 games)
Tactics 2725 (453 problems in 3.1 hours, 55.6% pass rate)
Mentor 2062 (I've barely done any of this - 202 lessons in 0 hours)
All of us surely don't have same rating for everything. Here you may post all of your ratings, so you can see which one would be your weak spot and share it with others. I have recently seen some players where tactics rating is smaller than blitz rating which is quite unusual.
My ratings are:
Blitz - 1224, bullet- 1280, standard - 1135 (havent played for a while), tactics - 1570, chess mentor - 1750, online 1400.
I would probably have to do on my standard game rating, not only because of number 1135, but to practice thinking a bit slowly (i know to sometimes really blunder bad because i dont think enough).
