Grandmaster Michael Adams probably missed a win just before the time control in this game against GM Rapport at Biel last month. As a consequence, he faced a difficult technical task here in this unusual 7-man ending beginning after White's 54th move.
White is a piece ahead; his problem is that he has the wrong coloured bishop
for the h-pawn. This means he cannot consent to a rook exchange unless Black were co-operative enough to let it happen
on g6 where a pawn recapture would be decisive. The black passed pawn makes it awkward for White to concentrate his forces but mating possibilities mean
that in the long run the stronger side should win. The tablebase says White can mate in 24 moves but, unsurprisingly, there were some
slips on the way. The first plan Adams tried nearly worked; his second attempt succeeded. Eventually he won in 116 moves.
