Slow vs speed chess

Hello and thank you for sharing your experience. I am terrible at Blitz so whilst I do play it I only do so for fun. 15/10 is my more 'serious' format and I am making slow and faltering progress there. Ultimately it will come down to what you want to achieve (progress vs. enjoyment). Good luck.

You know what, blitz and bullet really help your openings. I'd say bullet even more. You're forced to find your comfort lines and drill in those ideas. Then of course longer time controls is where you work through everything a lot deeper.

I'm not in a position to guide you other than that the received wisdom is that speed chess (Rapid, Blitz and Bullet) doesn't train you very well for classical matches. If you want to improve at classical you should practice at long time controls. Without having the experience to support it, I'll venture that speed chess trains shallow analysis while classical requires a deeper form of analysis which can only be learned by spending much longer looking at moves. I know from my own experience of Rapid that I have a tendency to "just try something" on a puzzle, if I don't have the solution after a short period of time, which I recognise is how I often play in my Rapid matches.

Are there benefits in general for blitz as a chess player?

It depends on your goals and its a fairly personal question.  They train different skills I have studied openings more than is probably "correct" if my sole goal was to improve as a player.  I'm also fairly good at calculations  but put me in a time 1 second increment time scramble in bullet up a piece and its still 50/50 I lose. If i play without increment I get enough advantage both on board and time to flag most players and win at my rating but I'm not sure what getting an advantage from my opening knowledge then running my king my a circle with premoves really does for my chess but it is fun.  I mostly like blitz and bullet simply when I don't have time for a longer match and still want to play.  5+5 blitz is  little slower pace and my rating is much closer to my rapid rating if I play this way but I still suck in time trouble. Playing bullet and blundering left and right feels terrible but even if you look at 2000 bullet player games they do the same thig just not as often. It often feels like in a slower time format your looking for the best moves in faster time controls your looking to play "good" moves fast instead. One thing that helps me keep my accuracy up in bullet is I focus on my opponents moves and try and keep calm I've noticed if i feel panicked the blunders start to fly if I can keep my heart rate down and focus on the threat of each of my opponents moves I do ok.  Either way one game a day isn't a lot I feel like my rating only goes up when I'm playing hours everyday and if I stop it does fall off a bit.  I say play them all focus on what you like best and have a good time don't get discouraged if the play looks terrible in faster time controls. Happy chessing 

Thanks for your response buddy! I play mostly one game only because of how much time is left in the day, and 15+10 is intense the game can take a lot of time and energy
