If Statement Block of code best practice

i have silly question paying attention small stuff because plan on getting certified end of year or sometime next year.

i read best practice use opening , closing brackets if statements in event or else adds code later.  this makes sense me not remember read when re-factoring code can uses compound statements , omit brackets make code cleaner.  which method best practice according microsoft?

//    if(boolean)     //  else    // or else  
  // or    if(boolean)  {
  //  }  else  {
  // or else  }

its argument if want simple readable code or short one. thing keep simple , add braces break head on how turn 1 line , make impossible read. @ least thats opinion.
