Interesting pattern (now that I'm in the 700s range on chess .com) is that I don't have to manually check that (almost) all my pieces are defended. Like even when playing on instinct/very fast I have enough spatial awareness to not leave pieces hanging for no reason
I was thinking maybe 'pushing the line forward' like this is a good strategy but it isn't . Keeping pawns in a row is devastating at the end game (when pushing them forward for queening) but creating all that space behind your lines is not useful in the middle game
Another situation that nobody expects a 550-level player to figure out, but that came up in play ¯\_(ツ)_/¯ I made the wrong choice and went from winning to losing... the blue arrows are the 2 next moves the computer thinks I should have made
This is what I mean about calculation getting complex at the 500s level... how am I supposed to figure out whether this opponent is going to checkmate me in the next couple moves
(The computer says that black was completely winning but eventually it was a draw through stalemate)
A pattern is that the engine always disagrees with taking these 'back rank' pieces (rooks or king) into a higher row when dodging threats in the middle-game, better to move them sideways. I guess geometrically it increases the 'surface area' of potential threats and tactics
Finally did one of those 'slam bishop into a king-adjacent pawn' moves that the computer likes to recommend... and its analysis gave it a double exclamation for 'brilliant', lol (cause I could then capture opponent's queen)
Apparently this tactic is called 'Greek gift sacrifice'
One thing I know for sure is that when someone parks their bishop near my ranks like this, they have some evil plot in mind... if you don't block/repel the bishop, you are going to suffer from some ruthless tactical combos
Actually this move where I bring the knight to protect the f pawn when they move their queen back is not something I figured out myself, or from looking at computer analysis... I got it from a Youtube video. So studying lessons from other people is definitely a thing in chess
