Bullet Tricks for 2000s

If you are a high rated bullet player, then you know that premoves mean everything. For me, I premove almost my entire opening sequence when I can. Especially when you're playing hyperbullet (30 + 0), or hyperbullet increment (0 + 1), you have to play fast. I used to always try and premove e4 Nf3 as white, and get smacked in the face with scandinavian.
One trick that I learned is to premove capture the square d5 in order to prepare for Scandinavian. Now, you may ask, "What if my opponent doesn't play Scandinavian, after all it's just a single opening??" The idea is that if they don't play Scandinavian, you can't capture the pawn and the premove won't register. To prepare for this, you have your second move, for me it's Nf3 hovering over the square. This way, you take up next to no time and you don't blunder your e4 pawn to the Scandinavian.
This trick works with many other positions as well, where there are a few different continuations to your opening. For example, when playing the Dutch: Playing Dutch against d4 has many continuations for white. If you're black, you have to be ready. Let's say they play e4. You can't premove stonewall because then you will find yourself in an inferior position after exf5. You can use the trick mentioned above to premove capture e4 and hover above the the square you would place your pawn for the stonewall.
Flagging is a process when you try your best to make your opponent run out of time, instead of going for a checkmate. This is usually done when the opponent is already about to run out, which is most common in bullet games. I'm sure that most people reading this already know what flagging is. The thing is, when both players are running out of time, the person with more time may not necessarily have the time to think on how to flag. They usually move very fast, and if attacking, go for checks. Checks are a really good way to burn through your opponents time because they can't move any other piece besides their king, unless to block.
The problem with this is that experienced players can predict where you're going to check, and dodge it with a premove. I've played many games where my opponent has survived way too long on 0.3 seconds because of this. A better strategy is to slowly block off escape routes of your opponents king. Technically, the move takes the same amount of time to think, but it is more effective. For example, if your opponent's king is on the last rank, with your queen on the second to last rank, most people would just move it down with a check, especially if both players have less than a second left. Many times the opponent can predict this, and move the king up where the queen used to be restricting, and flag the attacker. Instead of moving the queen down to check, try just moving your queen closer to the king to close off areas of escape
I have one last trick for you to try out in this blog today. When you are playing a pawn endgame, with the pawns on a relative standoff, the deciding factor to who will win can be who is bolder. If time is running out in a bullet match, say 5 seconds for both sides, there is a trick with the pawns. You can sacrifice a pawn in a terrible way, anticipating your opponent's premove or fast, uncalculated move. If both players had a lot of time left, this would of course lead to your opponent getting a promotion. But, if they move too fast, you can get a breakthrough.
I have won many games using this tactic, and many masters use it too. If you look at bullet endgames, I'm sure you will find many examples where the losing side comes back because of this. There really no counter to this trick if your time is running out. My advice is to not get paranoid about this, but instead play solidly until you see the opportunity.
This concludes the bullet tips I have laid out for you here. There are many more out there, you can start with these. If you use these bullet strategies ingame, I'm sure you will get better. Also, don't get these tricks mixed up with ultrabullet tricks. If you play ultrabullet tricks like the fried liver in a bullet game, you're screwed. Lastly, I would be so happy if anybody reading this could respond in the forum with ways you make YOUR bullet game better. I'm constantly trying to improve, and I love chess very much. Thank you for reading!
