Normally I don't present long games because most players, myself included, are not looking for long endings...we want snappy tactics. But, what makes this game interesting is the unbalanced material in the ending. Those types of positions are always difficult to evaluate and engine evaluations can sometimes be misleading. I have posted numerous times on this situation and here is yet another example of the difficulties involved!
