Best-move calculators

Stuck mid-game? See the best move, and why.

Set the board up as it stands. Six solvers rank every legal move and explain the ranking. The three positions below were analysed by the same engines the calculators run.

CheckersCheckers position, Red to move. An arrow shows the forced double jump from square 18 over squares 14 and 6 to square 2, where the man is crowned.
Red to move

Checkers

18×9×2. Red's only legal move, because captures are forced. The jump takes two men and crowns on square 2.

Open the Checkers calculator
ReversiReversi position, Black to move. The corner square h8 is ringed as the best move; b7, diagonally beside the empty corner a8, is crossed out as the trap.
Black to move

Reversi

h8, the corner. It flips a single disc, but a corner can never be flipped back. b7 flips four and sits diagonally beside an empty corner, which is how corners get given away.

4 in a RowFour in a Row position, Red to move. An arrow marks column 5 as best; column 4 is crossed out because the square it uncovers completes a Yellow diagonal, shown with a dashed ring.
Red to move

4 in a Row

Column 5. Column 4 looks natural but loses on the spot: the disc you drop there uncovers the square Yellow needs to finish a diagonal.
