Lots of dodgy customers playing 2 1 bullet?
If you are a coach whose income depends on your rating, I see why computer cheats would bother you. I would not care. I don't know why they care about their rating, other than as a sign of not improving. I enjoy crush weak players just as much as being crushed by stronger, or going toe to toe with equals. Surprise is good.

how do you cheat in bullet?wont using an engine actually cause you to lose on time?
That's why it is not easy in 1min. But in 2+1 or longer there is enough time to use an engine

You do realize there is HUGE difference between 1/0 bullet and 2/1 bullet?
Well, if you didn't, now you know. I have spoken about this before here, about an invisible "wall" in 2/1.
Many bullet players earn their rating through playing 1/0 nonsense and winning on time, but 2/1 is a different animal and you can no longer do that.
I do not think most are cheating, but here on Chess.com you do meet many 1600 bullet players (who play 2/1) who seem to play rather well for that rating range. If they are all cheating, this site would have to ban them all and then nobody would be left playing....
Cheaters usually have certain red flags you will notice, e.g. taking time to move in the opening, or moving at a same pace.
1600-1800 here is like 1800-2100 on a certain site elsewhere starting with an "L".
Was bored playing 1 0 so had a few weeks playing 2 1 instead. Rating plummeted all the way down to 1730. What struck me was the high quality of play in many of the games. Often I would lose games where I had played reasonably well (for the time limit) yet was being beaten by near perfect play.
Seems to me a lot of suspect characters (you know what im talking about) try to build up a bullet rating by playing at 2 1 as anything else is too quick for their skulduggery. There nothing worse than having all your ratings over 2000 but a bullet of 900 it kinds of looks suspicious, so some of these peeps seem to have latched onto 2 1 as a means of hiding their true nature. Am I wrong here?
