Reason 1.)Fragile against rooks/queens
Imagine your opponent’s rook is placed on the first rank,your king is check,you must draw at least 1 piece or more to defend it.If there is none,you’re done.You get backrank mated.The solution to this problem is easy though,but it can sometimes waste your attacking material at the same time
Reason 2.)Fragile against diagonal batteries
Its a big issue when your opponent is impatient to checkmate you.When your opponent is threatening kiss of death checkmate capturing the h pawn,you may play g3,but it was a big mistake because a bishop can now go to h3 to cause some problems.Same issue with the g pawn
I wasn’t saying that 3 pawn defend king thing is the worst defense.I rather say its…ineffective.I rather do g3,bg2,Nf3 0-0.
Pawns in front of the king (and for that matter, all pawns along the second and seventh ranks) are comparable to insulating wrapping around copper wires. The insulating layer minimises the risks of us getting electrocuted if we were to accidentally touch the wire.
a phalanx is the strongest formation:
chains can create color complexes behind them;
bobbing & weaving is often better than blocking.
