Draw

If there are no pawn captures or checks in 50 moves, the game is a draw.
No exactly. According to the FIDE rules, after 50 moves the players can claim a draw, but they do not have to. After 75 moves, however, it is a mandatory draw.
If there are no pawn captures or checks in 50 moves, the game is a draw.
No, that's just wrong.
9.3 The game is drawn, upon a correct claim by the player having the move, if:
a. he writes his move on his scoresheet and declares to the arbiter his intention to
make this move, which shall result in the last 50 moves having been made by each
player without the movement of any pawn and without any capture, or
b. the last 50 consecutive moves have been made by each player without the
movement of any pawn and without any capture.
