I fully understand where Meat is coming from. In these positions its not just the lack of time that is bad enough, its also keeping a clear head. I do not handle these positions at all well.
When I started this thread my intention was not to discover how to handle time-trouble more effectively, but rather how to avoid it altogether. This was what was troubling me so much. Here are my findings, so make a cup of tea and get comfortable....
Indeed, the idea of 'shuffling' without really changing the position is a good one, and I believe the answer more of less lies here. Being able to manoeuvre without changing the fundamental nature of the position is more difficult than it sounds, however players such as Karpov (always my favourite player) have shown themselves to be excellent at this. This is they key to it and its not something I have ever really been able to do quickly. There is no point 'shuffling' if it takes you 5+ minutes per shuffle move. This has always been my problem. Essentially, I am wasting time on moves such as this, rather than having it in store for the critical part of the game that is to come. Jockeying for position is an essential part of every sport, it occurs in football/boxing etc. As Meat's story demonstrated - there is no use in getting a wonderful position if you do not have the time to finish it off.
Therefore I have been changing my strategy, with some success. I have been doing two things, which I shall explain. These may not be relevant to everyone, but they are to me. Hopefully others will benefit too.
Firstly, and most importantly, I have tried to continue thinking and analysing on my opponent's time. This might sounds obvious, but for years I pretty much switched off/went for a walk/grabbed a tea or coffee/looked at the other games in progress when it was not my turn. Therefore, when it comes to my move I have had to start my analysis from scratch. Now, by thinking on my opponent's time I am much closer to making a decision and produce a move in a fraction of the time. Basically, all this time I was only doing half of the thinking that my opponent was. Against weaker opponents you can get away with this, however, against stronger or equally rated players I could hardly hope to achieve success operating at only 50% capacity.
Secondly, I have changed my view of the clock as part of the game. In the past, the clock was merely something that got in my way, something that prevented me spending the time I needed to play to my full potential. This is a bad way of seeing it, and I have adjusted this view, which runs thus......
a game of chess is fought on two fronts, the board and the clock. Winning on one front will not bring success if you lose on the other, as Meat's example showed. I therefore try to fight against my opponent not only by producing the best moves that I can find (see point 1) but also pressuring him by trying to stay up on time. This is my goal, to pressure my opponent to breaking point on both fronts. I know how awful time pressure (and the psychological demons that go with it) can be, and my opponent has more chance of going wrong/cracking if he is pressured on both fronts. By my slow play, I was unwittingly giving my opponent all the time he needed to relax and produce the best moves.
This is my solution, which I am only just starting to implement in my own games. In my last 6 games I have actually been up on time(!) in 3 of them

, while in the other three it was service as usual for me

. The only downside to this is the amount of mental energy expended. This is ok for 1 game a day situations, but for tournaments with 2 or 3 games/day I find that I am struggling to sustain this high-tempo chess. Maybe I am just getting old!
