Learn from your losses

Yesterday I wanted to do another live on twitch, but my scarce skills with OBS did show up and I recorded the video only locally. Too bad, because I did quite some puzzles, and then won 4 rapid games out of 5. I will soon do another live, no programmation yet until I do not have some followers (how can I get any without it, you will say). But that's probably material for another post.

Today I want to do some considerations about the game that I lost.
If you want me to upload somewhere the recording from yesterday night, just ask! I could also do a live with the analysis of the game, possibly also seen from both sides. For the time being, I will link the game for reference:

So, let's finally go to the lessons from this game!

• I was getting tired, so they are mistakes I could prevent by playing during the day instead that at night, but it's always good to recognise them. On top of it, if I know there are some mistakes I do more often when tired, it's easier to prevent them and to think twice!
• I did not consider candidate moves at all. A beginner mistake can be to consider too many candidate moves, but I should not stop at the first decent move, there could be a better one. For example at one point I had the chance to defend a knight with either a bishop or the queen. It is better to deploy a lower value piece as a defender, but I saw the queen first and I was happy with it
• I got stuck with one idea for the wrong reason, castling long. I thought I would have ruined my pawn structure kingside to take a bishop, while it was not the case. I got stuck with this idea for quite some moves, until I noticed that the pawn structure was totally disrupted queenside and was forced to reconsider. I could have castled before without this wrong idea
• I was not performing a blunder check for every move...
  • Am I moving to a safe place?
  • Am I moving out of a relative pin? (Sorry, my dear queen.)
  • What are the opponent goals with their last move?
• I was playing hope chess after I offered my queen for the price of a rook, hoping in a blunder from the opponent more than trying to create and identify some strong tactics. Easy tricks can work on less strong opponents, but rarely do with somebody that already gave sound proof they are stronger than you.

Did you notice any other generic rule from this game? Or less generic ones that you would like to discuss?

How do you deal with playing when you are tired, distracted by other problems, or when in general you do not have the perfect situation to do the perfect game?

Featuring @brevettd. Thanks for the great game, that taught me a couple of lessons!
