I need Newcastle not to win, not to score in the 1st half, under 2.5 goals and a West Ham lead during the match
To win your match, you need to have two correct answers in the first three penalty questions and it won't matter to you whether West Ham will take the lead or not.
Note that penalties we have in the cup are like penalties in a real football match. Players first go for 5 penalties and if they are tied, they go for the sixth penalty. If they are still tied, they go for the seventh penalty.
Since you and your opponent have three different answers in the first five penalty questions, whatever happens, the winner will be decided without any need to sixth to eighth penalties.
