Devastatingly Savage attack by 12 year old

The following diagram shows chess position reached by 12 year old Magnus Carlsen who is now the most dominant chess player on the planet.



I don't want to tell you too much about this position other than a stunning move exists that forces checkmate. Notice how most of Black's pieces are away from the action(not placed well defensively) which makes a sacrifice even more imminent.

Remember that many sacrifices are irreversible and require exact calculation. One error can allow the enemy King to slip out and the attacker will usually lose since he is minus the material required to continue to fight.

So with White to move, see if you can discover what went through the mind of the current world champion over a decade ago? When you see the move, you will certainly be able to share what  must of been a mind rush  for the exceptionally talented pre-teen chess player!!
