Fight For Your Knights
In analysing my game where I was on the Black side of a Queen's Indian and lost (https://www.chess.com/blog/blohmoremoney/believe-in-your-own-ideas), I had much trouble finding how to improve on 18. ... Qc6.
GM Bojkov suggested that it's really the Black Knights that have much difficulty getting involved in the game.
I had attempted to use the Knight to blockade at c6, but a more active continuation is to seek a home at c4 as per the following.
I really like this ... h5 idea, sacrificing the a-pawn to prepare Kingside weakening and likely perpetual check.
This game analysis has helped me appreciate that I must strive to get the most for my pieces. Avoid passivity!
