Some part of a mistake is always correct. – Tartakower
Once again a glorious and haphazard victory when my opponent lunges at White’s 1. g3 position. Well, that’s oversimplifying it. White’s position was genuinely inferior to the point of material loss, but care was required. My Candidate Master opponent played nervously and moved a bit too rapidly and found his way to a lost position.
After my opponent’s 10 … Nb4! material loss was inevitable for White. Black won the exchange, but it cost him his fianchetto bishop. White could then have exchanged on c5 and snarfled Black’s c-pawn immediately which would restore something close to material equality, but the plan of applying pressure on the long black diagonal was irresistible, despite the flaw that after 16 … h5 White’s knight could have become marooned on e5.
Black’s impetuous lunge was really 16 … f6 which justified White’s previous play and allowed White at least equality. But after that, Black’s fashion of cleaning up the mess on the kingside caused Black to lose a pawn. Grabbing it back in time pressure was a game-loser.
At the end, Black resigned, because on 28 … Ke5 29. Nf3+ Kd5 30. Qd8+ White wins the bishop with check, and if 28 … Kg5 it’s mate in 7 starting with 29. Ne4+ !
