<Name: Arno Middelkoop
Sex: Male
Birthdate: 29 May 1988 (27 y.o.)
KNSB (Koninklijke Nederlandse Schaakbond) rating as of November 2015: 1793>

My name is Arno Middelkoop and I live in the Netherlands. I'm currently 27, and I've been playing this wonderful game from the age of seven.

In that year, 1995, I joined the local chessclub here in Zoetermeer, Botwinnik. I enjoyed playing with fellow novice yooth players, and I intended to become a better player than most of them and did that. Even so, in the six years to come I probably only reached an official rating ~1500, not being active in any external competition.

As of November 2015, my KNSB rating is 1793. In the last two years my chess progression has been stagnant, now I'm trying to improve openings and getting a solid tactical vision. I started playing on under the name Qoko, yet I'm still somewhat rusty in Blitz (only ~1550).

Me outsidei of chess: I'm a graduated Biomedical Scientist at the University of Leiden, with a speciality in epidemiology, still looking for a PhD. I'm a Japanese RPG, Anime and Manga fan, although it has been less and less occupying the last years: I enjoy the franchise more than actually being an addict. I (still) have a general addiction for World of Warcraft yet I have been playing much less the last year.

Where you find me here: I am almost always occupied on the daily puzzle, although I do not post as often lately.

TheaN: Tuesday 11 December 2018 <26.?> There's something unappealing to exchanging quantity over quality: I guess it's a human trait. We'd prefer something better (Rook) over more of lesser value (two pieces). Especially in Blitz I find it extremely unnerving to go into a B+N vs R ...

TheaN: In a way it's a bit sad for Black that White ended up not needing his most aggressively posted piece for the final combination.
   Nov-29-18 B Jacobsen vs D Mallaghan, 2008 (replies)
TheaN: Thursday 29 November 2018 <28.?> White has a considerable amount of pieces around the Black King, and Black is taking his away, especially the major pieces. Seems like a plentora of moves wins here, the strongest being the game line with <28.Rxg7+!> simply starting the ...

TheaN: Wednesday 28 November 2018 <19.?> Now I am on the right track, or rather, finish the game swiftly with <19.Rxh7+ Kxh7 (Kf8 20.Qf7#) 20.Ng5+ Kh6/Kh8 (Kg7 21.Qf7+ Kh8 22.Qh7#) 21.Qh3+ with 22.Qh7+ and 23.Qf7#>. Alternatives work as well but if possible just mate, And now ...

TheaN: <abuzic: Excuse me Sir, but my comment was about the position after <32.Nd4>> It was. And I'm looking even more moronic than I already did. Guess only a well timed Homer "DOH!" is in order. To keep it at least a little bit on topic: after 32....Nh3+ it's obvious f3 is ...

TheaN: <al wazir & paavoh: Perhaps 27.- Nf6 28.Rxe8 Nxe8 29.Qc5 eyeing both Qf8# and Qxa7 was too scary...> Not scary, winning. In that sense 28....Qxe8?! may even be better as 29.Qxa6 Nc6! 30.Rc1! is considerably harder to envision for a blitz game. 27....Qf6! is indeed much more ...
   Nov-21-18 A Stukopin vs B Hasenohr, 2008 (replies)
TheaN: I was certain I recognized this one and I KNEW the fork on d7 played a part. However, as blind as am compared to my 2009 self I completely failed to realize Black played g6 to <attack the White queen> and actually wanted to start with <24.Nf6?<>>. Perfectly fine ...

TheaN: <PawnSac: NO! after 27.Kh3 NOT ..Qf3 but the immediate ..Qg4# !!> Intestering concept here (you do make it a bit more dramatic than necessary: unless Black has one second on the clock #2 or #1 don't exactly lose games, also, it's confusing now because you mean 28.Kh3 in the Nxe2

TheaN: Monday 12 November 2018 <41.?> Okay, perhaps the other moves win as well, but the key of today's Monday combination is that the text is entirely forced and takes out all Black forces; any other move keep some usable pieces on the board for Black. <41.Rxe8+ Qxe8 (Qf8 ...

TheaN: Friday 9 November 2018 <18.?> I have to admit I stopped calculating at what was probably the most critical point of the <18.Nxh7?!> variation. It's obvious White can start a destructive combination on the king side, but how? <18.Nxh7?!> is not best but does win: A)
