From your last review
BLUNDER
Decision 15 · 6-1 · -0.184
You played 24/17. The board wanted 8/2 6/5 — You broke the anchor while trailing in the race. Navid pointed on it, you danced twice, and the game — and the match lead — was gone.
OPEN THE FULL REVIEWYour coach says
“You are consistently leaving unnecessary shots when you are ahead in the race.”

The coach
Your edge, every game.
GAMMON'D learns from every decision you review: the anchors you break too early, the doubles you never offer, the gammons you let slip. Then it prescribes exactly what to practice next — position by position, never generic.
“Your checker play is improving, but your cube decisions are costing more equity than your checker mistakes.”
