I'm not questioning really how or when white could have drawn this. Probably at
many different junctures. I am doubting your previous claim that move #43
poses a good test position however. You claimed that 43 Re2 is the losing move.
My request was , what is white's draw plan here at move 43? Sure Re2 loses but
what move doesn't lose?
