In a slump after moving up limits

I was consistently beating the .10/.25 NL games for about 6 months. I recently decided to move up in limits to .25/.50 NL because my bankroll was well equipped (over 1K) and the lower limits were just boring me.
I had some success early on, but in the last 7 days i have taken a 4 max buyin swing in the negative direction (roughly 200 bucks).
I'm sure my play has not been perfect, but i'm wondering if this is a normal variance. I haven't had the greatest luck either, missing draws and having good hands get busted, but i'm wondering if i am overplaying some hands or just simply getting outplayed.
My question is do i chalk this up as typical variance and just plug away to get a larger sample size or is there anything else i can do to get through this? My sample size is 2000K hands, which i know is nothing, but i don't want to play 10K more hands to find out i am not good enough at this level either lol

If it was me, I would move back down in limits or at least set aside a limit as to how much more I could lose.

Why do you find the lower limit so boring?

One of the key elements of profitable poker is playing at the right limit and if 50 NL isn't working out for you, there is no shame in going back.

Maybe it is just down to bad luck, but chances are it is the higher standard of play.

$1k is only 20 buy-ins for $0.25/$0.50 NL. Although most players would say 20 buy-ins is the minimum you would want, I would certainly want more, especially if I'm going into a new limit. I've definitely had 4 buy-in downswings in the past, and I expect to get them again in the future.

Also, finding lower stake games boring is all about perception. You may be treating the chips in front of you as money, which they aren't. They're tools of the game, and the only value they have is their ability to get you more of them.

If you treat them as cash you run the risk of undervaluing them ("I'll call that bet, it's only a quarter") in the low-stakes games, and overvaluing them ("I could pay off my cable bill with that bet. No way I'm calling") in the high-stakes games. Both positions are dangerous, and chips should only be valued as a percentage of the total chips available to be put into play. (ie, your stack and that of your opponents)

$1k is slightly over-rolled for 25nl but imo nowhere near rolled enough for 50nl, i wouldnt move up til at least $1.5k but it depends if you could replace that $1k easily enough, i'm going to presume you can't (like a lot of people) and would recommend going back to 25nl until you hit $1.5k, my bankroll strategy is a 30/25 one, meaning that i move up a limit when i've got 30 buyins for the next level and if i ever drop 5 BI's then i move back down to the limit i was at before.

4 BI'S over 2k hands isn't really anything major to worry about, its just a regular swing, one of the regs on here just dropped back to 25nl after moving to 50nl and losing 5 BI's in 5k hands i think, just play at 25nl until you've built up enough in your roll and take another shot at 50nl, good luck

4 buy-ins downswing is nothing. Happens all the time when you play some volume.

Move down, though. you're quite borderline on BRM, and downswings do affect your mood which affects your play. Better to go past that at a limit you know you beat.

Also, 50nl is indeed harder than 25nl. It's entirely possible you're not a winner there even if you beat 25nl. Work on your game.
