} 18. Rae1 {White would rather have Black take, and protects with the rook.
The black queen is pinned, and has no choice. } 18... Qxe2 {Take. } 19. Rxe2+
{Take with Check. } 19... Kf8 {Black walks into the pin (knight)} 20. Bc4
{Here, White exploits the pin with the bishop. } 20... a5 {Black ignores the
pin. Perhaps he's going to move his bishop to a6 to trade bishops, or play b5
to scare the white bishop off the square. } 21. Rxf7+ {Here, the magic
"See-Saw" begins. } 21... Kg8 {Black has only one move. } 22. Rxb7+ {Rook
takes Bishop, with revealed check. } 22... Kf8 {Black has only one move. }
23. Rf7+ {Check with rook again. The see-saw continues. } 23... Kg8 {Black has
only one move. } 24. Ra7+ {Rook attacks black rook, with revealed check. }
24... Kf8 {Again, black has only one move. } 25. Rxa8+ {Rook takes rook, with
check. } 25... Kg7 {Black attempts to protect his rook, but white has another
move up his sleeve. Do you see it?} 26. Re7+ {Check .... winning another rook.
} 26... Kf6 {From here, white could continue. Rf7+, winning the rook on h8,
etc. In total, with a simple "pin" -- the magic "see saw" wins a knight, a
bishop, and two rooks. Watch for this opportunity. It doesn't happen often. It
only occurs with an attacking rook on the 7th or 2nd rank. }
