Resignation Trap: Bisguier put in a bid for the brilliancy prize here.26. Nf5! was good, though fairly obvious.
Black can't defend with the obvious 29...Ne5 due to 30.Bxe5! Bxe5 31.Qh6+ Kg8 32.Rg3+ Kh8 33.Rg7! and mates.
30.Rxc4! was also excellent. If 30...Qxc4 31.Bh6+ Ke8 (31...Bg7 32.Bxg7+ Kg8 33.Rg3! kills) 32.Nxd6+ wins.
32.Rc7! was also great. If 32...Nc5 33.Bh6+ Ke8 34.Qg5 mates.
Bisguier falters just when he is on the brink of victory. Instead of his 33.Nxd6? he should try 33.Bh6+ Ke8 34.Rxa5!
Feuerstein mixes it up himself with 34...Ng3!? Simpler was 34...Nxc5 35.Qxc5+ Re7 36.Re3 Rae8 37.d6 Rd7.
At the end, the game was adjourned and the players agreed to a draw.
