Checkmating with premove

In Blitz or bullet, it often happens that I'm up on material with King+Queen vs King but only little time left (e.g., 1-2 seconds).

In this case, I usually just premove my king+queen all over the board until my opponent's time has run out (because he needs to answer checks he cannot premove everything). But premoves still cost a very short time off the clock and I would prefer if I could checkmate somehow.

So I wonder: Is there a way to deliver certain checkmate with King+Queen vs King doing just premoves?

If you're using pre-moves, your opponent may choose to move less than optimally (unpredictably) and you then find you'll have to restart your sequence perhaps several times.  Pre-move does take 0.1 sec/pre-move.  So, 1-2 seconds left means only 10-20 moves.

Making valid premoves is not a problem in K+Q vs K. I'm just moving the king behind the queen and moving the queen is always valid obviously (if not, my opponent would have moved into check).

But yes, premoving does take down the clock slightly. That's why I would like to have a technique to mate reliably on premoves.

it is not always, there are several patterns that need to be covered sometimes

Yes, it's easy to mate. But that's not the question. The question is whether it can be done with premoves only. I.e.: Is there a sequence of moves that you could do to checkmate without looking at your opponent's moves?

The Q+K v K checkmate is THE most common checkmate in all blitz and bullet games.

If you want to win, you HAVE to know how to execute this ice-cold, and with <1 sec on your clock.

You can ALMOST premove all the moves.

There is a key pattern to learn - there are some youtube videos and online instructions on how to do it, but I have to admit that most websites do NOT instruct you on this method.

3 stages:

1. Move your Q a Ns move away from the K. If it's his turn to move, and your Q is already a Ns jump away, move your K to zugzwang him, and then move your Q a Ns jump away. 

These N jumps push the K to the edge of the board.

2. You are done when his K is on the edge, nearly in the corner - you want your Q a LONG Ns jump away (google it) - if you keep your Q a N's jump away and he is in the corner, you will stalemate him!

With the Q in this position, his K is restricted to 2 squares of movement.

3. It's easy now to premove all the K moves until your checkmate him in the corner. 

I find this Ns move technique much more reliable and premovable than the rook-like cutoff manuevers that are typically taught for QK mates. 

Here's a 1600 teaching a 1900 how to checkmate with a king and queen. 

I employ the same technique as the OP just because it is very hard to predict where the opponent's king will move, if you premove very close to the opponent's king as the 1600 player suggested, you will most likely hang your queen.

you might want to be careful what you say in the forums.

Correction:

A 1600 teaching a 1450 how to checkmate FAST with K+Q.  Compare blitz to blitz ratings, not blitz to the much softer slow ratings.

Yes, but in this case, if you make the K move instead of the Q move on move 5 as white, black cannot keep his king in the middle, so the method I showed is both theoretically AND practically best. 

For those who don't know this ice-cold, it's really worth practicing it against the computer until you can do it pretty much instantly. I routinely checkmate opponents in <1 second with premove in blitz games in this position, and with <2 seconds, I usually have enough time to even mess around and walk the king all over the place for fun with premoves before checkmating him despite the super time crunch.

Thanks for the replies. Yes, moving the enemy king to the corner and then just walking the king close is a good strategy. Problem is that even walking to that corner is not save. In your example, if I premoved the Q moves:

Here, the opponent can actually take my queen if I blindly moved forward. So basically I have to make sure the opponent didn't  side-step to catch me on premove after each Q move - i.e., I cannot premove any of these moves.

At 0.5 seconds per move and ~6 queen moves until the opponent king is at the wall, that's 3 seconds wasted (yes I am horrible at thinking under time pressure )

Of course once the king is locked to the wall I can premove the rest.

If you want to do it with 100% premoves (except for the last move or two when sometimes you have to look out for a non-mate or a stalemate) then move the king and queen 1 square at a time while keeping them in contact... like this

You'll probably have to pause on the premove to play the move that cuts them off on the last rank (like move 14). With some practice though, you'll see it coming and you can premove that too.

I was thinking about the same problem (1324 Average Opponent Rating) and I think there must be a way at least to premove every next move, maybe even the next two moves, with blocking squares with the king. Greetings from Berlin

If only I could also premove in over-the-board games...

Black to move, a premove checkmate is possible

You mean four premove checkmate moves are possible after 1...Kb1.
