Endgame: Defensive Piece Sacrifice

Core Lesson Objective: The Golden Rule: If you are losing, look for a tactical opportunity to sacrifice your remaining minor piece for your opponent's last non-rook pawn, forcing a drawn Rook Pawn ending.

Endgame: Defensive Piece Sacrifice

Position 1 / 1
Position 1/1 • Starting Position (Black to Move)
White has a Knight on f5 and a passed h6-pawn. If White keeps the Knight, they win. But Black's Bishop can execute a saving tactical sacrifice!

Mainline (6 Moves)

Move 1 / 6 1... Bxf5+

Black plays 1... Bxf5+! sacrificing the Bishop to eliminate White's only helper piece.

Move 2 / 6 2. Kxf5

White must recapture with 2. Kxf5. The Knight is gone, leaving White with only the h6 rook pawn.

Move 3 / 6 2... Kg8

Black plays 2... Kg8, rushing to get in front of the pawn.

Move 4 / 6 3. Kg6

White tries to squeeze Black out with 3. Kg6.

Move 5 / 6 3... Kh8

Black King plays 3... Kh8, tucking safely into the corner square.

Move 6 / 6 4. h7

White plays 4. h7, resulting in stalemate! The defensive sacrifice secured the draw.

Alternative Path Available — Consider: Played in the Game: Bc2?!

Alt Step 1 / 6 1... Bc2

Black plays 1... Bc2?, trying to save the Bishop instead of sacrificing it.

Alt Step 2 / 6 2. Kg5

White plays 2. Kg5, bringing the King forward to support the passed pawn.

Alt Step 3 / 6 2... Kg8

Black plays 2... Kg8, trying to establish a blockade in the corner.

Alt Step 4 / 6 3. Ne7+

White checks with 3. Ne7+, forcing the Black King to make a decision.

Alt Step 5 / 6 3... Kf7

Black plays 3... Kf7, attacking the Knight.

Alt Step 6 / 6 4. Ng6

White plays 4. Ng6!, a brilliant blocking move. The Knight shields the h6-pawn from the Bishop. If Black captures with 4... Bxg6, White recaptures with 5. hxg6+, winning easily.
