As multiple game matches are designated a colour I was overestimating the ratio of whites to blacks in your games, in fact there is almost nothing in it, 73 whites and 69 blacks in decisively completed games, and 6 draws, 3 with each colour. Your results are somewhat better with white, 49 white wins to 43 black wins and 24 white losses to 26 black losses. I've compared results by colour for all the players with established ratings and of the eighteen only one has better results with black. Among the higher rated players the difference is slight but for lower rated players white wins are far more common. In the games played between the top five rated players white wins by 16-10 so they appear to balance their ratios by winning with black against lower rated players. As the game is asymmetric in both force and aims it would be strange if there were no bias and it seems easy from these figures to conclude that white has the advantage, however it's also possible to suggest that black is more difficult to play, after all black has more pieces, more possible moves and therefore a greater likelihood of making a mistake. A further point is that of the eighteen players with an established rating ten appear to have a preference for black.
