Try the first position

Calculate and play mate in two moves for your side.

Seal the corner
Intermediate · 8 min
The black king has little space. A rook can draw a defender away and leave the decisive check to the knight.
Coordinate queen and bishop
Intermediate · 8 min
The black king is exposed. The first check may force a block that changes which piece controls its escape squares.
Deflect a defending rook
Toward 1800 · 8 min
The king is boxed in beside its rook. Look for a sacrifice that removes a pawn and displaces the rook before entering the eighth rank.
Attract a defender and open the entry
Toward 1800 · 8 min
Your rook and queen can coordinate against f7 and g6. Before sacrificing, calculate where the king will stand after the second check.
