How to beat Stockfish Llv. 1-8 in Ultrabullet

@penguingim1 aka PenguZero aka penguengine1 seems to the first one who managed to get a win against all different strengths here on lichess.
Check this collection of all games where he won against the engine in Ultrabullet (1/4+0).

Level 1

The easiest version of Stockfish is the very fastest one but penguin proved that it is possible not only to beat but to flag the engine.
Only 134 moves needed to finish SF off on the clock.

Level 2

Fast but bad as well. RIP level 2 after 7 tries.

Level 3

Fast but bad. Only 7 tries needed for success!

Level 4


Level 5

Not unbeatable but at least 33 games needed for a win.

Level 6

The sixth level turned out to be the hardest one. Penguin was close to insanity but he held himself together and finally scored a win after 127 losses.

Level 7

Too slow! Flagged in the first game :check:

Level 8

The grandpa. Even I managed to flag it ;)

Conclusion: Stockfish is NUTS!
You can beat an engine (implies) you are an engine ;)
I’m sure Kasparov will hire you next time he wants to play Deep Blue.
Just wanting to say that I've managed it as well, even though I'm no way near flagging Level 1 which is just insane.
For people interested, here are the games:

Level 1:
Its just so fast...
I had #2 in my very first try but slipped my Qh2+ followed by Qh1# with Qh1+?? which resulted in 39 other tries needed until I got it in game 40:


Level 2:
Quite similar to the first level. Got it on try 29, which were like the scariest last moves ever, as I had a forced mate but had to switch from g6 to my Ra1 to take his last check and then making the long mating move, all with little time left. Reminder to better not do this ever again xD


Level 3:
Still bad but I noticed an increase of games where I basically didn't got near any advantage at all. So this was my longest playing streak needed so far. After 50 tries it more or less let itself get mated, phew


Level 4:
Surprisingly was beaten after only 4 tries. Maybe because I looked up Opper's startegy of cool mating attacks.


Level 5:
I got the feeling now and second try: mate. Still too fast for sensible flagging, but even at that strength it still falls for saccing mate attacks.


Level 6:
After leaving Level 7 this was more easy. The strength increase is only really noticable from 6 to 7, so it was just a matter of getting the attack in. Still took me 22 tries. Whohoo, over a hundred games less than Andrew :)


Level 7:
This is from my point of view more or less like Level 8 just with speed, which makes it incredible hard to beat (at least for me as I'm way too weak in comparison to penguin^^). After like 100 failed tries I switched to Level 6. The main problem was that my usual tries of mating attacks were in vain while SF was still quite strong enough to blow my tries to set up a fortress and flag it. Needed another about 100 tries to finally get my fortress in game 203 and flag it.


Level 8:
Yeah, its slow but not that slow anymore, meaning you can't play too bad. I think my strategy was just not so great in hindsight as I got mated a lot of times because I failed to trade queens. Still managed to flag it on try 20:


Just as a note: In Hyper I got every Level except 6... (I gave up after 43 tries as its way more time consuming, but maybe I'll try to complete my engine scalps there sometime).
Was a crazy time and I'll definitely won't do it again xD
To make it complete I also got Level 1 in every variant, but had no intention to even try and beat any other Level.

Crazyhouse:
It just play horrible but dropping pieces is even more time consuming, so still not too easy. Needed 6 tries:


Chess960:
This is basically normal chess but somehow my "training" made me fast/strong enough to beat it in my second try:


King of the hill:
It just can't really defend against a rush to the centre, so yeah, three tries:


Three-check:
By far the easiest of it all (okay, except atomic I guess), as it won't really defend against checks, so only one game needed:


Antichess:
I'm certainly no expert in this variant but Level 1 is even worse, so it wasn't too hard. You must just get all your moves in and be cautious with forced takes. Three tries:


Atomic:
Well, yeah. It just plays like every beginner in Atomic would play, so it mates itself in a few moves. One game:


Racing Kings:
Just race. Too bad if you lose your pieces to easily and get blocked but its not really requiring skill, so try 4:


As a fun notice:
In my first try I made a really funny draw, which seems like totally random in Racing Kings:


Horde:
This was brutal at first. With black you have a hard time getting all pawns removed and I actually never managed. As white you have to hope it blunders horribly, which it did in game 23:


I guess it can be fun but a really sensible challenge would be to beat the stronger ones in longer time control. Still congrats to everyone who beats the engines in low time control. And @penguingim1 is just crazy fast, good job!
