He told me that it was very simple and showed me two defensive positions and Philidor's winning method. A short time later I forgot about everything he showed me and was left with the conviction that Philidor is the greatest genius in the history of chess, as he analyzed this endgame with incredible accuracy and probably without a computer, as he did it in the 18th century. I feel less bad seeing this ending routinely screwed up by grandmasters—probably it isn't that easy for someone who isn't Philidor. 111... h5g6  112. f3g4  112... f7f6  113. f4e5  113... f6a6  114. e1e4  114... a6b6  115. e5d4  115... b6b1  116. g4f4  116... b1f1  117. f4e5  117... f1f5  118. e5e6  118... f5a5  119. d4e5  119... a5a6  120. e5d6  120... g6g5  121. e4d4  121... a6b6  122. d4d3  122... b6a6  123. d3g3  123... g5h4  124. g3g1  124... a6b6  125. e6e5  125... b6a6  126. e5f4  126... h4h3 [%c_effect h3;square;h3;type;Mistake;persistent;true] Mistakes are inevitable, although my fellow Brazilian GMs Vescovi and Fier boast of playing this endgame with precision and always getting the best results.
