u could hv finished the puzzle by doing a checkmate. Your next move should be:-
4. Qxf7 Ng7 or Nf6 (opponent can just prolong the game by 1 move only)
5. Rd8+ (well i m sure u know how to checkmate)
6. Rx???
Deflection: Tactic #3
Sort:
BTW, it can be countered
1. Qxd6 Qxd6
2. Rxd6 The rook can move to any square in 8th rank except c8.
No need for the opponent to take your rook
This is one of my cooler tactics...I just played it in a blitz game! Enjoy! (White to move, by the way.)
