Frequently Asked Questions

Should I pick upsets in my bracket?

It depends on pool size. In small pools (<25 people), chalk often wins. In large pools (500+), you need upsets to differentiate. The key is picking the RIGHT upsets, not forcing them.

How do I pick a champion for a large pool?

Look for 'leverage' - teams with higher win probability than their ownership percentage. Often 2-3 seeds offer better value than the most popular 1 seed.

What's the best bracket strategy?

Match your strategy to pool size: chalk for small pools, contrarian for large pools. Also consider if your pool has experts or casual fans - expert pools require more differentiation.
