<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.

   Dec-11-19 Duras vs P P Saburov, 1906 (replies)
TheaN: After <27.Bxh7+> White demolishes the king side. At the mercy of 27....Kxh7 28.Bxg7+ #3 and 27....Kh8 28.Bg6! #7, Black will have to play <27....Kf8 28.Bxg7+ Rxg7> Kxg7 still leads to mate and Ke8 is hopeless <29.Rxf6 +-> and White goes on with demolishing. ...
   Dec-10-19 K Treybal vs J Engel, 1932 (replies)
TheaN: The key today is essentially the overworked Black Queen and the power of the d6 pawn. Typical, as the start of the combination does not involve the d-file at all. After 33.Nxh6, White is threatening to soften the d-file with NxN and play Qg6 to relocate the power. Taking the sac ...
   Dec-09-19 W Napier vs Teichmann, 1904 (replies)
TheaN: On this relatively straightforward Monday Black mates with <36....Qg2+> with <37....Qf2#>. Interestingly, I missed Qf2 is also mate after Kh4, wanted to play g5#. Being able to play just one variation and premove the last two moves is a bonus though (not necessarily ...
   Dec-05-19 S Martinovic vs Luis Neves Da Silva, 2017 (replies)
TheaN: I have a struck of blindness here, actually considering 31.Rb3+ <#2>: missing the Nc8 intervention at all, and after 31....Nb5 32.Rxb5+? (thought it was mate) not considering a6. Typically SF considers it the best move after 31....Nb6 32.Qc5 +- or 31....Nb5 32.d6!, if 32....Rxd6
   Dec-03-19 Saemisch vs J Engel, 1928 (replies)
TheaN: <Antonius Blok: <TheaN> First time he set down on f5 19.Nf5 ... Bang Bang Bxf5. (...) TheaN: Yeah, true, as that's before move 20 :). However, after Rxf5, Black's position is pretty crushable. And Samisch would have crushed that. Take note that even then, White is a short ...
   Dec-02-19 Didier vs Marshall, 1900 (replies)
TheaN: <25....Qxc4+ 26.bxc4 Bd3#>. Interestingly, White is getting mated already on move 24 and unless he starts to throw all his material at Marshal (literally isn't very nice though) there's not much White has against QxB+. Or rather, there <isn't> anything against QxB+ except ...
   Dec-01-19 A G Murphy vs C Witte, 1957 (replies)
TheaN: Wow, the only way I can describe this is that Black blew it and White just let it happen anyway. The sac is completely flawed (looks strong, perhaps, but that's just superficial) and really <only> as late as 23.Rb2? does White really give up allowing 23....Nf3+ 24.Kh1 Ne1 -+. ...
   Nov-29-19 Pachman vs J H Donner, 1955 (replies)
TheaN: I <do> think this Friday is supposed to start at move 25, as White can play 25.Re7! ± at virtue of 25....Qxc4?! (Qg6 ± holds for now but Black isn't exactly doing great), 26.Rxg7 +-. I didn't calculate it entirely, but was confident we could sac c4 due to the first

TheaN: <sfm: and play d4-d4> this day's get weirder by the second ^^.

TheaN: That said I do prefer the Classical or Steinitz personally, just because of these very tactical (sometimes TOO tactical) variations.
