RARE?? I beat Stockfish without setting up a wall...

I beat stockfish with this (but first I lose 49 games against stockfish) but then the 50 th game I win: https://www.chess.com/live#g=5647590678

The KID or Czech Benoni are basically your only options for beating (flagging) fish stock.
But notice Stockfish's a-pawn is on a3(!) not on a4. He had very decent a pawn break, it wasn't a real "wall".
