Now what the heck happened in the end? Anand gave up a knight advantage, purposedly for a clear cut draw. I have no clue why he did that this time. He took queen with queen, clearly, knowing it would be lost to king, and then again the pawn with knight. He had a knight, of all things!

> Anand gave up a knight advantage, purposedly for a clear cut draw. When you assume that a world-class GM played "purposedly" for a draw that would lose him the championship title, you're probably wrong. > He took queen with queen, clearly He was in check. Taking W's queen was the only way to avoid losing his own for nothing.

  are you sure about that? the king could have moved back up, but in front.. moved from right side to left side between those two lines, without moving in front of the queen line.

    And he would have lost his queen thus loosing the game.

    If Anand played the king to the eighth rank instead of to h6, Carlsen would have kept checking on the seventh and eighth ranks, with a draw by perpetual check.

      Just to make sure I am absolutely clear, I am talking about 61...Kh6, which enabled Carlsen to play 62.Qb6+ forcing the queen trade.

It was the best option in both cases. He was in check when he took the queen, so the queens had to swap or black would lose his queen. At the end Anand traded his knight for the pawn as a king and knight (black's material) can't win, but a king and pawn (white's material) can, so it is in blacks best interest to swap.

  what rule is that? are you implying even if only white king, black king, and black knight would be left on board, it would be a draw/win for white by default? Instead of trying to isolate white king into a corner for checkmate? Never heard of a rule like that. Are you sure?

    Combinations with insufficient material to checkmate are: king versus king; king and bishop versus king; king and knight versus king; king and bishop versus king and bishop with the bishops on the same colour. - wikipedia

      Then you have the situations where a check mate is possible but cannot be forced. King and two knights against king cannot force a check mate, but if the player with the lone king knows what they're doing and wants to get check mated, they can help the other player to win. If I'm not mistaken, that counts as a draw even if the clock flags on the player with less material.

    You can't checkmate with just a king and knight. Isolating into a corner won't help, as the king can not get close enough to keep the opposing king "in place", and while the knight can try to keep the king cornered, there would be no positions where the knight can check where the checked king can't escape the check by safely moving towards the knight. EDIT: There would be positions where you don't try position the king to try to hold the opposing king in a corner where the opposing king can't move towards the knight to escape a check, but in those positions it will be able to move away in other directions.
