In order to be good at chess, a player must at least think three moves ahead. For grandmasters of the game, they even think up to five or six moves in advance, giving them a distinct advantage as they have already anticipated what their opponents will do.

For Jan Gustaffson, he proved that he is not only good at predicting his opponents' moves, but also those of NBA teams.

Even before the Boston Celtics and Cleveland Cavaliers pulled off the blockbuster deal on Tuesday centered around Kyrie Irving and Isaiah Thomas, the German grandmaster already knew what was going to happen.

“..You think you wanna throw all that money at Isaiah Thomas? He's kinda cancelling himself out by his defensive and shortcomings, is he not? So I think. here's what I think they should do, try to trick Cleveland, give them well Isaiah Thomas and Jae Crowder and well one of your 80,000 draft picks, get Kyrie Irving…”
