The white chess king begins on the e1 square and the black king begins on the e8 square. This should be the opposite color of the king. If the e1 square is white, then you will need to rotate the board so the e1 square is dark.
It is generally considered that white has better chances of winning in chess. This is due to white's initiative, since white gets to move first. The difference in chances seems to get more significant, as the level of play gets higher.
If black moved first, it would take some getting used to for players who are accustomed to white going first. This would be especially true for the opening moves, since the white and black chess armies are positioned slightly differently. For instance, as white, the queen is on the left-hand side. As black, the queen is on the right-hand side.
In many of the chess puzzles, it was common to see each problem presented as white who has the winning sequence. In fact, Theophilus Thompson (1855-1881), the first Black player of note, had authored such a book of chess puzzles. 59ce067264
