Puzzle 4820: 5. 44-40 is also winning, +3.5 after letting scan calculate for a little while.

Open your study. Press the options button looking like three bars on the top left. Next to the number of members. At the bottom left there are buttons for clear chat, and delete study in red.

@HawaiiBlue capture with the king should be done to field 2 instead of field 49, then its winning. Correct solution probably entered wrong.

https://lidraughts.org/training/2504 12-17 on move 3 is also winning

https://lidraughts.org/training/89 21-26 and 21-27 are also both winning (-5.4 and -3)

For puzzle https://lidraughts.org/training/4525 25-30 can be played as move 1, 2, 3, or 4, but is only accepted as move 1, 3, or 4.

@kalnap Because I saw 11x13 was easily winning, so I didnt bother looking for alternatives.

For puzzle https://lidraughts.org/training/3641 11x13 instead of 3x1 is also winning. Scan gives 11x13 a score of -5.2 at depth 36.

@debestespelerooit 49-44 allows black to play 35-40 after the shot, with a drawn endgame.

For puzzle 4983, starting the combination with 22-18 instead of 21-17 is considered incorrect, but both are easily winning, with 22-18 actually being the computer suggested move.
