(Lisa Rougetet in january 2018)

The intervention of chance in a game is, in a way, a mechanism that takes the decisions out of the player’s hand. As combinatorial games are determinated, that is, without chance, there is a finite set of possible solutions, and therefore there is always a succession of moves which leads to victory (or to a draw). We can therefore build a winning strategy, which leaves full control to the player over the game, even if he has to anticipate the opponent’s moves.

SIDE EFFECTS

TURN: WHITE
LEVEL: QUITE BEGINNER-FRIENDLY

5-5. You play White. Black just dodged your attack by playing a side move (e8f9d8). Now it’s your turn. In any case, you win in 3 moves (:
