[FEN "8/5p1k/1P4p1/2P4p/2b4P/5Q2/5PP1/4qBK1 b - - 0 44"]
This position occurred on move 44 in the Carlsen vs Gelfand game in the World Championship Candidates, 2013.
Here, Gelfand played the losing move 44...Qxf1+. However, I analyzed the position after 44...Bxf1! and I do not see a win for White. Black sets up a blockade to stop the queenside passed pawns from advancing.
[FEN "8/1Q3p1k/1P4p1/2P4p/2b4P/8/5PP1/4qBK1 w - - 0 44"] 1. Qf3 Bxf1 2. Qxf7+ Kh8 3. Qf6+ Kh7 4. Kh2 Qe8 5. Qf4 Qd7 6. Qf3 Bb5 7. b7 Qc7+ 8. g3 Kg7
And how does White win? Black blockades the passed pawns. If White tries to use his kingside pawn majority, his own king gets exposed and could lead to a perpetual check.
