Getting better at OTB chess I live in a small town where there had been a total of 2 tournaments during last 5 years and 0 chess clubs, hence I have almost nil experience playing OTB chess. But sometimes I set up a board and play with my family. I have noticed that I miss a lot of tactics and obvious mates which I couldn't have missed while playing on Lichess. Also, I can't calculate properly OTB. I am shifting to the national capital this year where hopefully I would get to participate in OTB tournaments.

Is it a normal problem for those who play predominately online chess? How do I go about improving my OTB play?
One suggestion I have seen for how to improve learning when studying openings and tactics is to involve the other senses. This involves not just using sight, looking at the position on a computer, but also setting up the position on the board and playing through it (touch) and (for openings) saying the moves out loud (hearing) as you play them.

I was a bit sceptical when I read this but your experience backs this up. The obvious way to address this problem is to follow the advice and set up tactics problems on a real board so you practice "over the board".
