The Czechs are not chess fanatics like Hungarians or Russians, so you can actually relax and enjoy the game here. Naturally, when you have the other player’s king in jeapardy in English, you say „Check“. One would think that here, you could simply say „English“ to show the king’s about to get clobbered. But no, you have to say „Shock!“. No wonder more people don’t play here. Too much trauma and stress.
