I like Capablanca's style of play. Mozart's Rondo Alla Turca seems to fit quite nicely here.
What classical song best defines your style of chess?

Oh, definitely this one. Playing slowly, trying to be extremely careful at the beginning just making sure I'm safe. At about 1min 40 I realize I've blundered and the panic starts to set in. That's ok! I can still save it! No, wait...every move I make is terrible! What's going on?!? They must be using an engine! Maybe try another tricky move.. oh, I just blundered my rook as well...
The last few chords are the sound of my opponent performing a forced checkmate.
This song is titled Riders of Doom from the motion picture Conan the Barbarian. It often accompanies another song from that soundtrack called Riddle of Steel.
