Watches aren't allowed anymore. Recently a player was forfeited for wearing a watch.
Yes, internationally digital watches are not allowed.
In India, even analog ones are not allowed.
Going back to the top 10 of things to do:
While it is important to train physically/mentally and also train in chess, there is an important factor to consider - individuality. I remember a funny incident mentioned by Timman (if I remember right). He read Botvinnik on how to prepare for a tournament, so trained up on physical stamina with long walks etc. Then arrived early to the tournament, and went to play. Lost badly because his adrenaline was at unusual levels. He just couldn't control his energy, so just gave up on the idea of borrowing someone else's idea of "training"
One should also remember that there are a lot of players who cannot sit at the board (includes me) even during a rapid game. They make their move and then start pacing about (I used to kibitz and watch almost every game in the tournament hall). Some settle down like a boa and leaving the board is sacrilege to them. So, doing what's natural for you is good.
Of course, you have to list down specific problem areas and work on ways to solve them. For example, playing too passively when on the backfoot may be remedied by training with positions of counterattacking possibilities etc..
Crazy but timann i thought (correct me if im wrong) also smoked the funky stuff. I dont think he is the best example to relate to.
Oh, I didn't know that about him...very interesting. But the point is that you have to work out a training schedule for yourself. And "current theory" is not good enough :-)
always bring a jacket
leave the water bottle outside
1. Come fresh (washed, dressed and well rested for every round).
2. Be aware/informed of the rules of the tournament - eg. Do not bring cell phones/watches that can give a default lose/ban
3. Prepare good time management - Going to work and doing a tournament in the afternoon can be very tiring, while it would be nicer to open up your schedule.
4. Prepare a bit before the game, doing some tactics exercises can help keep you alert. Do not do to much analysis during tournaments as this can make you extra tired, but just enough to make you more alert during games.
5. Avoid playing fun games between rounds/before as this can be rather tiring and may affect results.
6. Prepare against your opponent beforehand if possible. Eg. find out what opening he may play and prepare a line against him/her for the next round
7. Stay focused and try to calm your nerves during the games. Do not fret over things that may affect your play like rating, just give the best game you can.
8. Enjoy the tournament.
I cannot think of 2 more things at the moment.
About "it's only a game", I think remembering you're in a tournament to win, not to "have fun" significantly improve your stubbornness, and your results. You'll be less inclined to waste a good position for a flashy sacrifice for example.
Also, I keep remembering myself to think on my opponent's time, which I inevitably fail to do, begin daydreaming and end up in time trouble.
Always bring several pens, paper handkerchiefs, a bottle of water, a tissue to clean your glasses, and of course a towel.
Some other about regulations: don't take any note on your scoresheet (no annotation except time left), never keep your turned-off phone in your pocket (but in a bag that you leave under your chair), never offer draw or adjust your pieces on you're opponent's time, never get up and leave on your time.
