This is a much better two-player variant than some of the non-official ones I've tried. It addresses the issues of wide-open board space by adding two dummy players (not as bad as it sounds) to help confine options. It compensates for the lack of trading with a forced trade mechanism. It also throws in an extra dice roll on your turn to help speed things up a bit. It is not as good as three or four players, but it does capture the spirit of the original game when you need a Catan kick and you've only got one other player.

I agree it is a great 2 player adaptation. I have been longing for a way to play the game with 2 players and this really helped. One irritation for us was the frequency the robber is rolled - you have about a 30% chance of rolling the robber on your turn, or about 52% chance it will be rolled on either your next turn on your opponent's next turn, which means you will often discard resources.

See detailed review of this variant here on BGG. (Note: I didn't write it!)

I think it looks good, except for the ability to move the robber with a trade token. Maybe if you could only move the robber to the desert with the trade token OR force a trade.
