Drill the 169 numbers
Two drills: pick the equity band, or say which of two hands is ahead. Questions lean toward the hands you keep missing, and two correct answers in a row master a hand. Every number comes from the same 400,000-trial simulation used across the site.
Pick the equity band against a random opponent. This is the main drill, and it asks more often about the hands you keep getting wrong.

FAQ
Is the trainer free? Do I need an account?
It is free and needs no account. Progress is stored in your browser's localStorage, so reopening the page in the same browser picks up where you left off.
What counts as mastering a hand?
Answering the same hand correctly twice in a row. The goal is all 169; mastered hands then come up less often.
Are the questions random?
Not purely. Unseen hands get the highest weight (5), hands you have missed are weighted by how often you missed them, and mastered hands drop to 0.4.
