PK -136 is the handicap, if game ends in 90 min (+injury time) in a tie, bet is a PUSH
+160 is the 3 way. You wil see a draw line offered there too, so if ends in 90 min (+injury time) in a tie, bet is a loss.
Both plays are for regulation time only. If you want to bet Italy to win the world cup (overtime and shootouts included) is a completely different bet.
