White: king e1; queen d1; rooks a1/h1; bishops c1/g2; knights b1/f3; pawns a2/b2/c4/e2/e5/f4/h2. Black: king e8; queen h4; rooks a8/h8; bishops c5/c8; knights b8/g3; pawns a7/b7/c7/d7/f7/g7/h7. Material is balanced. White to move.
Black's last move 1...Bf2+ is a desperado check—the bishop on c5 sacrifices itself to disrupt White's king safety. After 1.Kxf2, Black's knight on g3 captures the rook with 1...Nxh1+, but White's king escapes to g1 and the rook on h1 is simply gone. White has traded a bishop for a whole rook—a gain of about two points of material. The knight on h1 is now trapped with no escape squares (the g3 square it came from is controlled by the king on g1, and no Black piece can defend or reroute it). Black's queen on h4 and remaining pieces cannot generate enough compensation for the missing rook; White's king finds safety and the material advantage is decisive.
When your opponent makes a forcing check or capture, calculate whether the follow-up actually damages you or merely looks flashy. Here, Black's desperado tactics (check + rook capture) concede material because each forcing move comes at a cost and White's king has an escape route. In your own games, don't panic when your opponent creates threats—count material after the forcing sequence ends. A rook is worth nine points; a rook for a bishop (five points) is a permanent edge.
