Welcome to The People versus The Fish, in which the collective football expertise of Guardian readers goes head to head with the football expertise of... a fish.
Der Kaiser, a sunset wagtail platy coloured the black, red and gold of the German flag, has taken up residence in Farringdon Road and will be picking daily charity bets during the World Cup. Meanwhile readers will be voting each day for the bet we, the people, should place. Who will raise most money during the World Cup?
Vote for the people's bet each day here and follow The Fish Versus The People in the Guardian's daily 20-page sports section every day throughout the World Cup. Oddschecker will pay any winnings to the Saving Grace Foundation, supporting people needing HIV treatment in Malawi.
Here are yesterday's predictions:
The people
Germany to beat Costa Rica by one goal at 13-5
A one-goal margin of victory for the hosts was favoured by 35% of voters on the website yesterday after browsing a list of six possible match outcomes.
The fish
Germany to beat Costa Rica by two or more goals at 5-6
At the appointed time of 5.30pm last night Der Kaiser soared very definitely to section No1 of his six-section tank. He had chosen bet No1 - which meant he was nailing his black, red and gold colours firmly to the German mast.
