English Rat Defense

I am a d4 player and I analyse my openings a lot. I came by an opening called the "English Rat Defense":

I was curious, as this allows an early queen trade:

However, when I check the opening explorer, the majority of games are won with black despite losing the right to castle. Can you guys explain why?

thanks

I remember coming across this opening a month ago while messing around in the explorer and was like "Did some rat just crawl up on a chess board during a game in Englund around that certain position, freaking out almost everyone except the player who was somehow inspired to name the opening after the rat?"

The short answer is the king belongs in the center in the endgame, so if some more pieces are traded off, it can turn out that the queen exchange is just helping black prepare for the endgame.

It should probably end in a draw though. If black i winning then it may indicate white is pressing too hard for the win.

It's very simple. Black is clearly better. The c4 pawn is TOTALLY out of place. It hinders white's coordination. The king is not a problem. He'll go c6 Kc7. His bishop will go to e6 pointing out that the c4 pawn is out of place thus forcing white to go into the b3 Bc1-b2 development scheme which he'll counter with f6 blunting the b2 bishop forever. He'll have a million different plans on the queenside with like b6 and a5 or provoking weaknesses with the knights like: Ng8-e7-c8-b6 and Nb8-a6 or Nb8-d7-c5. 

And ask yourself the question: what is white's plan? He can certainly go for some kingside expansion but it's just inneffective. The play should be done on the queenside but again the c4 pawn just stands there like an idiot. I cannot imagine anyone wanting to play such a position as white
