Puzzles - Solve with me - Practical approach
I've never really liked puzzles much, but there is no doubt they are very important. Its not just about tactics and patterns, but for example, harder ones, 2000+ rated, train your calculation skills and emphasize how much is important to have structured and precise way of thinking and analysis.
I've recorded a YouTube video with me solving the puzzles I earlier failed - so each of these for different reason escapes my intuition. You can try to solve puzzles while I'm solving them and compare yourself to me for example and hear my thinking process. Depending on your rating, this might be very helpful to you. I am 1800+ rapid, 1600+ blitz atm.
Three things for example that I learned while solving these.
#1 Concentration - you can't really play chess with half a mind and expect anything. Its a common mistake. I've failed multiple 1500-1600 and even one 320 rated puzzle due to me moving the piece before reassuring myself that I calculated the moves. I watched twitch while playing.. not I good idea, I played hope chess basically and blundered many times.
#2 Checks, captures and threats - Its a golden rule. Sometimes you can find the best move instantly on intuition, but if that doesn't work go back to procedural way of thinking - starting with this rule. There's one endgame pawn race puzzle with Rooks in video where I torture myself for 2-3 minutes with pawn race - but I had a check I didn't consider. Turns out if I did that puzzle would be 5x simpler.
#3. Be thorough and precise - harder puzzles are harder for a reason. Its imperative not to repeat yourself and lose yourself in the position recalculating same moves. And don't move to other candidate moves until forced lines are exhausted in the one you are doing. Last puzzle in video I skip over one check in one of the first lines and lose like 2-3+ minutes searching around for the move which I should have already seen.
There is more to this of course, chess is hard. Video is here if you are interested.
