Why is rook to c1 not only a good move but the best move?

Mate in 1 for black

Is it really a brilliant move if you then blunder the next three moves?

How brilliant is this?

Why is this a brilliant move? I played d4 my opponent played this and he lost a rook.

can anyone explain why this is a brilliant move (why shouldn't black take the knight?)

First brilliant into a royal fork

This is an example of how useful tactics really are, i blundered my queen earlier in the game but I used a tactic here to get it back.

What about it?

Im only posting it here because i am 1000 rated and my opponent didnt even play bad. This game showed me just how useful tactics really are.

Guess my elo?
