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

@jeffreyq2 true, but why do you restrain from obtaining extra material which introduces clear win?

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

Hi all,

495, 3641, 4286 and 4487 will be removed.

1116 is not wrong, as jeffreyq2 also replied: after 49-44, the sticker move 35-40 follows with a draw.

Thnx all!

For puzzle 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.

puzzle 1399: why is the kingshot with 38-32 so much better than 37-32? I would say that both shots are winning. Do I miss something? Thanks for all the great training material! :)

Hi all,
Puzzle 4623 : the final position is draw, according to DB.
When White will get his king and control 5-46, one Black king won't be enough to win.

PS : keep up the good job :)

Hi all,

About 1399: no, you didn't miss something, both are winning:P funny how such old puzzel hasn't been found earlier.
About 4623: indeed, don't see a way to win there. Other draws can be made as well, so...

We'll remove 1399, 4525 and 4623

Thnx all!
