This is not relevant and there is no reason to force the player who want to win
to lose time.

The player should be allowed to move and ignore the opponent.
If I have 0.1 seconds for all the game and 2 moves to mate the opponent that I
prepare with the premove the opponent should not be allowed to win the game by
offering a draw that I may need 0.2 seconds to reject.

No

If he has no time he should lose the game unless the opponent has no material to
win even against mistaeks.

Player that is a piece down will usually reject a draw offer if he see that he
is going to win on time.

If You have no time you desetve to lose and offering something that you know
that you probnably cannot get is not nice.

The opponent should do nothing to decline(even not to press space bar)

It is better if the opponent need to press the space bar if he wants to accept
the draw.

I disagree about the fact that player have to use their time to reject the draw
and I also think that offering a draw should be done only when you believe that
there is no way to prevent draw or in equal position or when one side has an
advantage that is not enough.

It is also possible to cheat in bullet by having 2 computers(espacially 1+2 time
control).

I think that the most efficient way is to talk in the phone with a friend that
has a computer when you tell the friend the opponent moves and the friend tell
you the moves that you should play.

I agree that anything can happen espacially in bullet when part of the players
even do not know about the premove.

I use simply the name Uri_Blass

My current elo is 2001 bullet,2069 blitz and I also have rating above 2000 in
slow.

Today I have no fide rating(I had in the past more than 2000 and lost it and in
that time 2000 was the minimal fide rating and later I did not play enough games
that were considered for fide rating) but my israeli rating is 2103(it is
probably too high because I had a lot of luck in my last tournament and 2050
Israeli rating that is equivalent to 2050 fide rating is my estimate of my
playing strength).

I find that rating in playchess is dependent on the time of playing.
The best bullet rating that I got is 2131(I played a lot of bullet games and
chessbase did not save it) but there are times when bullet players play so
strong that I have problems even to get above 1800.

I think that there are players of both types and it is very important if you
have a better mouse than the opponent in bullet 1+0.

If you play bullet it may be also better to know some tricks in that game
For example if you notice that your opponent use the premove you can play stupid
sacrifices and I won the opponent queen by Nxf2 and Nxd1 because I saw that he
is using the premove too much.

It also happened to me that weaker opponent won my queen by Bxc7 and Bxd8
but I did not resign and drew the game and it is a mistake to resign in bullet
even if you are a queen down.

In one game I saw that the opponent can win the game by mate next move.
He played Rd1+ and the only legal move that I had was Be1 when he could win the
game by Rxe1# but I decided to play Be1 and not resign and my opponent simply
did not take the bishop(I guess that he imagined that the bishop is defended
that was not correct) and I won the game(inspite of it there are cases when I
resign and it is dependent on the level of the opponent and on the time that he
has to finish the game and time that I have to finish the game).

Yes

It is valid move but objectively it lose the game and it will never be played in
a serious tournament.

Always one player is spending more time.
It is impossible to prevent it.

I can add telling another trick that can be used against the premove not only in
bullet.

Imagine the following position
[D]8/8/k7/pp6/8/4q3/5RK1/8 w - - 0 1

black has a winning position so to simplify things he plays Qxf2+ and planning
with the premove a4

He does not consider nothing except the logical move Kxf2.
White is smarter and play Kh1 and the premove cause stalemate.


Finally I give example of justified thinking in bullet and I give part of one of
my games there.
I was black and thought 17 seconds about move 20 and I lost almost half of my
time but I found the only move and finally won the game.

Usually it is a bad idea to use 17 seconds for a single move but in this case my
opponent had more time so I knew that losing a piece is almost the same as
resigning.
