Hi there! "A Tactic" Is where you have to move to the correct square for example -
This is where White's up material, and can win the game. (White has an advantage) The king was in check, and had to move and then white would capture the knight. That wins a piece. and there are wrong moves in chess. For example the biggest blunder in history -
I do not understand what each of these "training session" wants from me. I make a move and it tells me its the wrong one. How is there any "wrong" move in chess? I didn't get into check mate even. Please some one enlighten me, what am I supposed to do here?
