Nice mate!

A lovely mate! Again, though, I can't emphasise enough how bad a tactic it is to assume that your opponent won't do something. Here, you hung a rook and a knight in the first few moves. A better player would never have given you a look-in after that. If you want to improve, you need to stop hanging pieces so easily.

Checkmates with minor pieces always looks good. At this level, once one side starts going downhill, that player very rarely can find a way to turn things around: the opponent has to make a complementary mistake to redress the balance. Had White seen betimes that he could win the a8-rook for nothing, or much less than the rook, he would probably have gone on to win. That would be just as true of higher levels of the game, of course. A rook deficit can rarely be made up (though D.I. Bronstein did it in a World Championship match game on one occasion).

OMG what a game. To be honest I think this is the first game in my chess career where a player was able to still win the game even though he had not played a single center pawn. To add to what Ion said, at higher levels not playing a center pawn would meet a swifter end then a piece capture. It is called a scholars mate. Which by judge how this game is played would have worked.
