This must have been a very painful loss for White. Imagine you have a grandmaster on the ropes and the fat lady is tuning up her vocal cords for the big aria when you miss the simple 24. Kb2 (or 24. Kc2). A few moves later, you follow up with 28. g3? and before you know it, your king is walking the plank. Kinda like that old Warner Brothers cartoon where Yosemite Sam has Bugs all tied up and out on a plank when Bugs gives the plank a kick and it spins around and Sam’s the one taking the fall.
