What does this bet mean?

I'm looking at Bos-Tor at 5dimes.

Sat 5/4		81 Toronto Maple Leafs	+1,+1½ -146		o4 -290
7:05PM		82 Boston Bruins	-1,-1½ +126		u4 +245

What does the -1, -1.5 mean?

[face]

means if bruins win by exactly 1 goal you lose half your stake. if bruins win by more than 1 you win +126
