The shortest time control I play is 10+0 and I feel that at my very average level, I don't learn anything from it (especially if I get on a discouraging losing streak). These days, 15+15 is what I try to stick to on Lichess so that's my preferred control (still considered fast by OTB standards). With that out of the way, I suspect that the difference between bullet and classical people is probably like the difference between a sprinter and a marathon runner. In my other spare time, I like to ride bicycles. Everyone who doesn't do it thinks it's a dangerous thing - but the way I ride isn't the way that most people think I ride. I prefer the slow, cautious, zen and analytical approach compared to the "intuitive" fast, mad rush that most people will be familiar with when they think "cyclist". I can go fast when required as I have developed and applied my own theory for it, but most of the time I prefer to just take it easy. So I see some parallels there - horses for courses. I don't really buy the idea that there's such a thing as intuition. Intuition to me merely means that someone who apparently demonstrates it cannot understand how to explain their intuition (http://www.thefreedictionary.com/intuition http://www.thefreedictionary.com/intuition). Many seem to be equating it to a higher form of intelligence but I don't buy that that is the case. I daresay that Fabiano Caruana is probably pretty good at classical now and can perhaps afford to practise shorter controls a lot more. He's actually not bad at it, but has had inconsistent results in the past. But who knows - in 2020 we might be seeing a lot less Rossolimo and Petrov.
