DIAGRAM 6.

Moreover, the latter cannot be taken by the Pawn on f7 as the
black King would be in check by the Bishop on b3. The Pawn is
"pinned" by the Bishop. Black's Knight cannot take White's Queen
either as he is pinned by White's Rook. Finally, there is no
piece available which may be interposed between White's Queen and
Black's King; in other words: Black is checkmate, his game is
lost.

If it were Black's move he would take the Pawn g2 with the Queen.
Now White's King is in check as Black's Queen threatens to take
him on the next move. He may not take the Queen as he would then
be captured by the Bishop b7. Neither may the Knight f4 take the
Queen as he is pinned by the Bishop d6. Moreover, the King may
not escape to g1, h1 or g3, these three squares lying in the
rangeof Black's Queen; and so there is no move on the board with
which to get White's King out of check: He is checkmate, White
loses the game.


Stalemate


If a player, without being in check, cannot make any move which
would not get his King into check, he is said to be STALEMATE. In
