user18217: It's white's move and the king can't move.
Why was this game drawn? I should have won it I think.


user12873: Welcome to the site. What you described is the definition of stalemate, not checkmate. The enemy king not being able to move anywhere (while it's not attacked) is stalemate. That's why the game was drawn.
For a checkmate, you'd need to trap the king and be attacking it at the same time.
If it seems weird that stalemate is a draw, you're not alone. The 3rd world champion Capablanca argued that stalemate be considered a win. Nevertheless, the rules of chess dictate otherwise.
