This position is from the game between Magnus Carlsen and Rameshbabu Praggnanandhaa played in the Wijk aan Zee Masters 2023. Magnus played 22. Rfe1? missing the opportunity to get a winning advantage with a small tactic: 22. Nxf7 Kxf7 (if Black doesn't take the Knight, White will just withdraw it and be a healthy pawn up) 23.Rf3! (23.

60. ... h3! was played in the 6th game of the World Championship Match 2013 between Viswanathan Anand and Magnus Carlsen. The doubled pawns are an asset to Black, giving him victory.

Ra3+ Ke2 64. b4 f2 65. Ra2+ Kf3 66. Ra3+ Kf4 67. Ra8 Rg1 0-1

Instead White wins in just three moves: 1. Nhf1 g2 2. h4 g1(Q) 3. Kf7! and Black is in zugzwang - he can't move the Queen without putting it en prise!
