<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: 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 ...

TheaN: I spotted the mate line, as well as white at least going a piece down otherwise. Lately I'm less into posting direct solutions as many do so (unless of course people want me to anyway). Intriguing is the discussion of white's alternatives. <patzer2> questions 14.O-O-O, but from ...

TheaN: I can post the solution like many others did before me, but more interesting... didn't I see this puzzle, or at least this exact pattern (Ng3 hxg Qh6 Qh5 Qxh5#, darn now I still posted it) before? I can swear I did, though I might just have a genuine deja vu.
   Jun-20-15 Ehlvest vs V Neverov, 2005 (replies)
TheaN: Did get the initial moves but missed 30.Bd5!! which is an amazing zugzwang move. I went for 30.h4?! directly, which keeps some advantage (due to the h5 threat) but surrenders the zugzwang idea. Typically, some engines have the option to analyze the threat of the opponent (so half ply ...

TheaN: Ah now I still erred in variation C. There is more to this position than some solvers make it to be. After <41.Nxc3 a3 42.Kb6> definitely the best try because the winning 42....b2! is not a natural move <42....Kc8?! 43.f6> to unstress the ending <43....gxf6 44.Nb5>: ...
   Jun-16-15 J Aabling-Thomsen vs J Van der Meer, 2005 (replies)
TheaN: Tuesday 16 June 2015 <20.?> Fairly straightforward Tuesday. Monday was odd, now Tuesday is too. White's queen is en prise; if he's forced to move it, white will lose most of his attacking possibilities after 20....Nf6 and 21....Rad8. White doesn't have to move her, but abuse the

TheaN: Monday 16 June 2015 <30.?> A Monday is a Monday, but anyone going for 30.Qa3+ will lose this game badly. Rook then... ah yes. <30.Ra1+ Kb2> when black accepts or captures Pb3, 31.Qa3# follows. Instead: <31.Qa3+ Kc2 32.Rc1# 1-0> is mate in three instead of two. Bit ...

TheaN: Tuesday 9 June 2015 <32....?> Slightly odd problem, in the sense that black is already up the exchange. It is crucial to spot white is actually threatening a mate in two with 33.Qc8+ Rxc8 34.Rxc8+ Qd8 35.Rxd8#. For that exact reason black can't play Qf3, though he would like to.

TheaN: And Qh6 is among a few variations that give white +4 to +5: Qxh7+ ends it immediately but it isn't necessary.
   Jun-03-15 Nguyen Hoang Tuan vs Nguyen Xuan Quang, 2005 (replies)
TheaN: What I describe is what I think is also the base of the flawed reasoning of 'overthinking'. We've all had it at least once that immediately when it's your move you know you can't play a certain move because of something. However in overthinking all your options, 'something' is ...
