I call them " Early Aggressors". Yes they are very beginners but still they can beat a comparatively better player.
Tip: Go all Defense, do not counter or try to respond to their attacks.
let them have their attack.
Try to drag game little further and "Early Aggressors" will leave serious weaknesses behind or blunder something.
im at 450 -510 and i wonder how people don't do any mistake during the whole game and then in the endgame they need almost infinite moves to find the obvious chekmate in one. (with 2 queens and two rugs...) maybe they use an engine and turn it off when they think they can do it alone??
