What I think is this game illustrates the danger of blindly following principles. Despite having the two bishops White should not open up the center; despite having the classic KID counterattacking position, Black should not play the natural …f5. But that doesn’t mean the principles are wrong! Instead it points out the need to identify when other factors make the principle inoperative. For example, opening up the center when you have the two bishops is fine, but not at the cost of giving the black knights outposts on e5 and d4 as well as an open long diagonal for the g7 bishop! Similarly, whereas normally Black has the c8 bishop to guard the light squares (and so can play f5 without worrying about e6) here the light-square is absent and that means Black has to be a lot more careful about playing a commital move like …f5.

Great choice of a game and instructive annotations! I am certainly looking forward to future posts from you.
