Improving chess

-dannyhume (variation of a quote from the late great Ken Smith, FIDE Master and world class poker player)

Use your free puzzle rush every day - that will help with tactics. There are other places on the internet where you can find chess puzzles.
Look on youtube for instructional videos - there are plenty, find someone whose style and personality suits you.
Play some games and then look back at them and try to figure out why you lost - or if you won, look at what bad moves your opponent made. When you look at a chess position look for moves that can give check, moves that can capture a piece and moves that threaten either check or captures - do this for both sides.
I need a couple of tips to improve in chess. I know few like to do puzzle and play long games. The tips also need to be free. Help me, please.
