Battle Of Equals

IT is very unusual in a swiss to be paired against someone with exactly the same elo, not least because pairings in each score-group are based on top-half (rating-wise) playing bottom-half.
But that is what happened this morning in round seven of the South Wales International.

White to make his 30th move in Anthony Hughes (1900) - Spanton (1900)

White is a pawn up and has an active bishop against a knight that is struggling to find an outpost, but his kingside is under strong pressure.
30.f5?
This leads to a quick finish.
Trying to save the g pawn by 30.g5?! is met by 30...Rf8, when Stockfish10 and Komodo9 reckon best play goes 31.Rc2 Rhxf4 32.Qxf4 Rxf4 33.Rxf4 Nf5. Stockfish10 assesses the resulting position as winning for Black, while Komodo9 gives Black 'merely' the upper hand.
Best was probably 30.Rc2 Rxg4+ 31.Rg2 Rxg2+ 32.Qxg2 Nf5, with what the engines reckon is more-or-less deadeye equality, but there is plenty of play left in the position.
30...gxf5 31.gxf5?
Better was again Rc2, but Black is on top.
31...Nxf5! 32.Qxf5 Rg4+ 0-1
