dont fall in this trap

At the first look we see that black have a big material advantage and can win the game easely. but when we have a winning game sometimes we stop thinking and just play the game.Here white made a trap and black  fall in to it because of his overconfidence....This is the position:

Now look what white played and what black should not play:

hey tony, just don't fall in this trap, okay? is that too much to ask?

That trap is commonly known as the "Legal's mate" name after the legendary

French chess player Sire de M. de Kermur Legal. This was the actual position

of his game againts by an opponent name Saint Brie in 1750.

Tony boy, just don't fall into this trap. Do we need to sound like a broken

record? (kidding) Thank you , anyway.
