The blitz match between Gary Kasparov and Nigel Short produced some entertaining chess. Kasparov probably chose the Black openings he did (1.e4 e5 plus the Modern Defence) because he hasn’t been playing much lately and no doubt wanted to avoid things that are too topical.
Nigel Short’s response was to play some old fashioned lines that probably aren’t too well known by Kasparov. The Evans Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.b4) was his choice in game 4 and then the Bishops Gambit (1.e4 e5 2.f4 exf4 3.Bc4) in game 6. Nineteenth century stuff and probably a good choice against former Soviet players in general.
Here’s a nice video commentary on the 6th game by IM Andrew Martin:
