I've only rarely encountered pre-moves in Daily chess, but that sounds very annoying.
I don't really understand the need for them in Daily. It's more appropriate for bullet, where every fraction of a second counts, not games which allow days for a move.
Conditional moves are great for positions that are forced, or have few legal options. Just set the lines and the moves get played so you don't have to do any additional work after the position you calculated is reached. It also can lower your average time per move as well, which may be of benefit to some members.
I am just noticing an interesting trend in my correspondence games of late especially in the Chess.com Daily Championship Tournament. I was curious if anyone else was experiencing it. I am playing various rated players right now but I have had a few opponents who have essentially premoved their way to victory against in correspondence chess after I think for a day or so. It is very demoralizing and I usually end up getting crushed by those people. Now, people can out play their rating in correspondence chess but when that person is lower than me in all rating categories on chess.com I will admit its easy to want to cry cheater especially after a day of thought I play a move, he or she plays a move i never saw, and then they premove the best response to a move i didn't even see. Anyone else seeing this? Or this is quite rare? For example I am playing a 1400 right now that just won an exchange off of me after a bad Queen move on my part. It was pretty forcing but he premoved the entire combination and Im just blown away haha
