Although I have long retired from serious chess tournaments (they take too much time, a luxury I do not have anymore - even more so now that I have two infants to help grow!), I insist playing online blitz on chess.com, with alternating fortunes. My elo rating hovers in the 2200-2300 range, signalling that I still have my wits around me (I figure it is a very good way to keep a watch on my mental capabilities: if Alzheimer lurks, I will spot it early). 
So today I played a pleasing attack, and I am going to let you figure it out. Playing the right moves in a blitz game (where you have 5 minutes to do _all_ your moves before you lose on time) is not trivial, and in fact many top grandmasters can falter too. So it is remarkable when you play with 100% accuracy a complex position...

 From the position in the diagram below white can gain a decisive advantage, or more if black is not extra careful. Your move! I leave some space before I unveil the winning combination.










1. Nb5! (threatens Nd6, but also Nd4 with a dominant position)
1.... Rc6 (black defends from the first threat, but white continues his plan)
2.Nd4!
2.... Rb6? (black errs, but also the relatively better 2.Rc4 left black insoluble problems)
3.Qxa5! (a free pawn, plus a continuation of the attack; Bg6! was also excellent)
3....Rb8? (black should continue with 3....Ne7, although the position is still lost)




And now comes the curtains move: 4.Qc5! and black has no defence. If Ne7, or even Qe7, there follows Nxe6++, smothered mate! Comparatively best is 4...Qd6 5.Qxd6+ Re7 6. Qxb8+ Re8, but I think few players would bring themselves to continue the game this way! A pleasing ending to a (rare thing) correctly played game...
