Before I was introduced to computers in 1979 with the Commodore Pet at the age of 10 I was into playing chess, I played for the Birmingham under 11's team that travelled around the UK, I also used to play in serious national chess congresses for various age groups and I also used to play in adult club tournaments beating most adult serious club players. I was originally taught by my grandad at around 7 years old, but he soon found himself regularly losing against me despite being pretty good himself.
When I was in the Birmingham team they provided professional induction tuition which made me become even better, to qualify for the team to begin with I had to go through various tournament trials and players were regularly retested in trials against other potential new players who wanted to take your place so it was very serious and highly competitive all the time.
Birmingham team games and any tournaments / congresses were extremely serious, you played in halls with adjudicators walking around watching your every move, in congresses I've also known lots of spectators watching with opera glasses from a nearby balcony with seating. The rules were extremely strict, E.g. there was a strict touch piece move rule and if you let go of the piece in a legal position there was no taking it back under any circumstances, when the game was in progress and you'd shook hands you were only allowed to say essential game related things to your opponent that were officially recognised such as "check", "check mate", "I resign" while knocking your king over, "do you want a draw?", "I accept", "I decline" Etc. and if you needed anything else you had to call over an adjudicator by raising your hand. For instance if a piece wasn't correctly positioned in the centre of a square and you wanted to adjust it without being told you'd touched the piece and had to move it, some players would say, "adjust" before touching it, but if it was possible to legally move the piece, to avoid any possible dispute it was always best to get an adjudicator to oversee it. You'd think it would be stressful, especially for someone on the autistic spectrum, but I would retreat into my own world when I played chess and I'd sit with my hands around my eyes like a visor so I could only see the board ahead of me and nothing else, I would actually slowly dig into the middle of my forehead with my thumb nails which always meant I had a nasty wound there that kept scabbing over. What also helped was there was no actual time limit on individual moves within reason, E.g. if you'd taken 30 minutes something would be said by an adjudicator, but it wasn't unusual to take 5 minutes on average to move and sometimes up to 10 or even 15 minutes on an especially difficult move. There was an overall game time which was usually around 2 to 2.5 hours and if you were still playing at the end an adjudicator would come over and then judge the game. He or she (it was virtually always a man in those days) would then speak to both players giving them each a chance to discuss what moves they had planned and argue their case, often the adjudicator would start making the likely moves while discussing them with both players and then the adjudicator would decide who had won or whether it was considered a draw. On most occasions both players would agree with the adjudicator, even if a player had lost and it was a quick + easy job if one player was obviously losing, but there was some long debates and discussions when games were close, then often more than one adjudicator would get involved before making a final decision.
I was always seeded no 1 in my school after repeated knock out tournaments and challenges to the title, but I began hating playing there as just one stupid mistake could mean losing my title which I was doing nothing but defend (it was very negative as I could only stay where I was or lose), it never happened though because I barely ever made mistakes, but at school the games weren't as serious and it would annoy me when players or other children watching started talking causing distractions Etc.
Ever since being introduced to computers this completely took over and even though I can still play chess quite well I have barely played since I was 10 and wouldn't be anywhere near as good as I was back then, plus I'd be expected to play even better as an adult. I'd probably now only be at a reasonable adult club level being so much out of practice and I'd be beaten by the best 8, 9 or 10 year olds, where as a young child I was in the top few in Birmingham for my age and I was beating most adult club players (I apparently caused quite a few adults a fair bit of embarrassment since they were beaten by a 8, 9 or 10 year old, I didn't see it at the time, probably because of being on the autistic spectrum and for some reason I didn't even feel like a child, but was later told by my Dad when I was older that some people really weren't happy after losing to me).
