Nice job! ( Personally I am bad at draughts but ok)
While you weren't any pieces behind, I think after 7 moves your basically in a losing position already
@PascalStil is +0,3 really considered a losing position (maybe on grandmaster level but on 2000 blitz idk)
@PascalStil Your statement is a bit ambitious. I don't deny that after 7 moves black excluded many checkers from the active play and, consequently, black must play defensively for a draw. Nevertheless, I'm not sure if white could convert positional advantage into winning sequence, given that sooner or later white should release the pressure with 30-34 which allows black to make an exchange 24-29 or 24-30.
