<Name: Arno Middelkoop
Sex: Male
Birthdate: 29 May 1988 (25 y.o.)
KNSB (Koninklijke Nederlandse Schaakbond) rating as of July 2013: 1805>

My name is Arno Middelkoop and I live in the Netherlands. I'm currently 25, 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 May 2013, my KNSB rating is 1805. In the past years my chess progression has been stagnant (from 1793 to just >1800 in two years), and definitely not as solid as I hoped it to be.

Besides chess I'm following a university course: Biomedical Sciences at the University of Leiden. As BSc I am now doing my final internship for MSc in epidemiology, doing research in orthopeadics.

Besides both chess and education 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, playing MoP now and my rogue Qoko (Europian Frostmane) is still ahead of the curve raiding wise.

Where you find me here: I am almost always occupied on the daily puzzle, as well as screening and sometimes posting on the GotD. However, aside liking to comment on less common games, I started to lurk the recent tournaments a bit more, refreshing my grandmaster chess knowledge.

TheaN: <Jimfromprovidence> interesting alternative, a striking difference based on the opposite colored bishops. In fact, it's white's only other move that keeps the advantage. For what it matters, Rd7 is a forced mate too, yet 22 instead of 6 :).
   Oct-19-15 Vaganian vs A Planinc, 1975 (replies)
TheaN: Mind that in that variation, 24.Kb1?? is a blunder on white's part due to the perpetual 24....Bxd3+ 25.Ka2 Nc1+ 26.Ka1 Nb3+ 27.Ka2 Nc1+ 28.Ka1 1/2, but if anything 24.Kb1 just surrenders a piece for no reason.
   Sep-23-15 R Comstock vs T J Szczypka, 1982 (replies)
TheaN: An easy wednesday indeed, and it's more because this one just comes by as a chain of events than anything else. Difficult tactical positions generally have an 'eureka' move, either the initiator or somewhere midway: those that initiate with such a move are generally easier. This ...
   Sep-16-15 M Pyernik vs P Moulin, 1982 (replies)
TheaN: Hm, the rook lift never crossed my mind. Bad, in a sense that it didn't occur to me at all, good, in a sense that I believed in the power of a queen and knight. The aforementioned combination is the most tactical combination of two seperate pieces in the game: though a queen and rook ...
   Sep-15-15 Delchev vs Topalov, 2004 (replies)
TheaN: Interesting to consider 33....Bb5+ as 34....Rxf3+ still works even after 34.axb5. After 34.Kf2 however: 33....Bb5+ 34.Kf2 Rxf3+ 35.Nxf3 Nh3# is beautiful. [DIAGRAM]
   Sep-03-15 Svidler vs D Khismatullin, 2015 (replies)
TheaN: I too settled for 28....Qxb2+?!, foreseeing the mate if white captures and foreseeing the win if white moves to d1. However, I did not make the connection with keeping the white king on the queen side with 28....Qa1+! Difficult to say where this failure of vision occurs; I guess it's ...
   Aug-31-15 H Klip vs C Janssen, 1982 (replies)
TheaN: <dfcx: 28.Rh3 also mates. only difference is that black can delay the mate by one move with 28.Qxh2+> That is in fact slightly more complicated after 28....Nf8! I looked at this in the sense that white could somewhat mock his opponent (if you see the double sac you see the sac ...
   Aug-13-15 Tal vs S Saeed, 1985 (replies)
TheaN: Thursday 13 August 2015 Typical in this position is the limitations on the white position. Yet, Tal probably saw the win from afar. White is down the exchange and facing the worst threats due to the g-file battery. After quick realization that Qh8+ and Qd6+ don't really end up ...
   Aug-11-15 F Vallejo Pons vs G van der Stricht, 2005 (replies)
TheaN: Interesting Tuesday, well summarized by <Penguincw>, <sneaky> and <Once>. When you see it, Nf6+ is a very logical move. If you however hit a brick wall, Nf6+ is very peculiar. It opems up the black kingside but is not forcing after that by itself. Atypically I was in
   Jul-29-15 A Belezky vs N Arsenault, 2005 (replies)
TheaN: The actual skewer and the point after 35.Qxa2 is fairly obvious. What's interesting is black allowing white a discovered attack that's completely futile. Often discovered attacks on the queen are disastrous, but the clearance of the board plays a part. The more clear a board is, the ...
