I don't think so. I see everywhere drawin lines. I was able to get a score of
"only" +0.7 for white while forward and backward analysing this position with
Hiarcs9.
In the final line Hiarcs wants to play 5.Kd3 and sees a smale advantage for
white, but this line also draws. I didn't find any way to improve the lines for
white. So I think this is a draw.
Below is my analysis. Note that this is the german notation so
K=King
S=Knight.
