Next time i will use a chessengine _before_ i post here. From your profile i see, you are a strong player. I explored the position a bit nevertheless, but could not find a hidden snag. If white opts for a draw, he should choose 38.Kg1... In this line black should force the draw soon. After 38.Kg3 black has more opportunities here and there but a convincing continuation is hard to find, if any. Oliver >> >>> >>>Oliver >>> >>> >>>>The sequence after Bxf3: 37. Kxf3 Re3+ 38.
