若い棋士が多少、尊大な感じになるのはよくあることで、 そういうことは将棋界に限った話ではないでしょう。 It often happens that young shogi players become a little self-important, but I don't think that's something limited to the shogi world.
The talented young chess player is very bold. He deliberately lays himself open to attack, makes himself vulnerable and then checkmates his opponent when least expected.
