I've never seen this before. I was playing a game on ChessArena.com, and I ended up getting something called a "Walkover".
My rating on ChessArena for that game was 1090, and my opponent's rating was 1281. He gave a "walkover" to me after move 4. The game was this:
[Title "Jaenisch Gambit Accepted"] [fen ""] 1. e4 e5 2. Nf3 Nc6 3. Bb5 f5 4. exf5 e4
I was playing as black. At this point, they gave me the "walkover".
Is this like him "forfeiting" the game (instead of resigning)? What's this mean? It gave me an increase in my rating, but I've never seen this before.
