increment chess sucks, increments totally ruins the flow of the game especially online. OTB it makes a little more sense since it takes like 1-2 sec to physically make a move. But still delay is probably better for that purpose.
I agree sometimes; disagree sometimes. I agree on anything over 1 minute should not have a increment. Like the 3+2 tournaments. Had situations here like On move 11 I have 2:45 left....other player has let their clock run down to 10 seconds. Then they proceed to move like crazy: racking their time back up. Thats just annoying; and a waste of your time. Not to mention; throwing your game off as you think they are giving up via flag. IMO you ought to be able to call time. Like in a 5 minute game; should be at least 1 move every 30 seconds. Or minute. or something.
However, I like increment on short time setting games. Like a 15 second + 5. Those are fun.
Compare 3+2 to 5+0. It needs more than 60 moves that 3+2 games last longer but nevertheless you can take your time in critical positions not being afraid to be flagged in the end in a winning position. Therefore increment creates flow because the position (and not the time) stays in the focus and more time is only guaranteed if the position is worth it.
