A battle against yourself

While the person sitting across the board from you is nominally your opponent, most of the time the person you are really playing against is yourself. This is because when you are trying to calculate a move, you are also trying to find the best moves for your opponent. So when things go horribly wrong it is usually because what you think must happen, turns out not to happen.
Here is an example for the ANU Chess Club last night. Adrian de Noskowski won a pawn on move 21 forcing Mario Palma to try and defend the position a pawn down. By move 43 they reached the diagrammed position, when suddenly de Noskowski came up with a plan to mate the White king. Unfortunately the plan had a major flaw, which can happen with both players short of time and only receiving a 10s increment per move.

Time trouble is often the cause of bad moves, but its better when both players are in time control because they miss so much stuff sometimes that the game really becomes a coin toss.

To some extent increments will help players find 'better' moves in time trouble (contrasting this to previous years when increments simply didn't exist), but still with only 10 seconds per move the pressure will still be on and that's when mistakes are most likely to happen.
