^ Chess is very addicting. Though your friend is acting like a sore loser.
There are two types of chess players. Chess players, and those who play for fun.
It doesn't quite seem like. I get that sometimes after I played a good game but made a extremely bad blunder. I just can't stop thinking about that game, and once and a while I get a bad dream or nightmare of it.
No day goes without them playing at least a game or two; when they lose, it is another matter altogether. The other day, I went for a sleep over at my friends; a very good chess player. When it was time to go to bed he was talking chess, "the game you won was a fluke!..bla bla...."; even when he slept, he was dreaming chess. In the morning I asked him what his dream was, and he said, “I could see clearly the move that lead to my down fall in the only game you beat me.”
Mhu! Is that an addiction or what?
