King S Indian Samisch

For sub-1000 ELO players

The King's Indian Samisch (ECO E81, Samisch Variation) gives White a stable edge of +0.5 according to Stockfish 17 at depth 25. Sub-1000 players frequently castle kingside without realizing that the Samisch is specifically designed to attack the kingside with a f3-g4-h4 pawn storm. The key is to prepare counterplay with c5 or f5 rather than castling into the attack.

Why This Opening Trips You Up

The Core Problem

Sub-1000 players castle kingside automatically without recognizing that the Samisch is designed to attack that exact area.

Before Your Next Game

If you see f3 from White in the King's Indian, consider whether castling kingside is safe. Sometimes queenside castling or delaying castling is better.
