<human>:  Would Lee Sedol understand the complexities of the Sicilian Defence?
<bot>: No, Lee Sedol is a Go player, not a chess player. Lee Sedol is a former South Korean professional Go player of 9 dan rank. Go has a different rule set than chess. It would not be worthwhile to spend time understanding the complexities of a game that you don't play professionally, so Lee Sedol would not understand the complexity.
