This is not the Dutch. The Dutch begins 1.d4 f5.
An opening is defined by the moves of both sides. 1...f5 is not the Dutch against whatever white plays. It is only the Dutch when 1.d4 is played. This could have transposed into the Dutch if white played an early d4, but the ...e6 and d3 moves made sure that it would not transpose into anything mainstream. The opening of this game was nothing more than 'the English.'
I don't play the dutch often - in fact just a couple times in the last few days - in this blitz game I actually won (some blunders by my opponent helped)- but my question is was this a sound line for the dutch? I just went by memorization on about the first 6 moves or so from a turn-based game I was playing
