Nothing new under the sun II

After playing Rhine-Boerkoel (see previous post), I found the following game, which has strikingly similar tactics. The most salient difference is that in the final position 18...Kxf7 isn't an option because of 19.Nxd8+. Had the game continued, Black would have had to take the queen, allowing White's rook to give perpetual check on g7 and h7.

The Greatest Game You've Never Seen

This is an amazing game by IM Nadanian, featuring his patented 5.Na4!? against the Grünfeld. The diagram shows the position before all hell breaks lose. The final position looks like a composition: despite Black's huge material advantage and all those pieces clustered around his king, he has no defense against the primitive threat of 18.Qh8#. Astonishing. This game deserves to be in all the anthologies.
