@jaki01 played flawlessly ...

Well ... look at this position from the last round:

Until then I had played rather well, but during the last moves my wife had already entered the room and impatiently asked me when the tournament would finally be finished. In the same moment while saying "Wait, please!!" I made already the terrible mistake 15. Rc7??, after which black could have won my queen with 15. ... Bg4+! I saw it immediately after making that error, but black didn't see it, so that I could win the game and the tournament.

It's really the sad truth that compared to my rating I make lots of terrible mistakes. An extreme example happened in the previous tournament:

I was threatening 50 ... Qg2#. White played 50. d5 but I 'stubbornly' followed my plan and played 50. ... Qg2+?? to lose very soon, instead of simply taking the the bishop at e3. :-)
