<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: Monday 17 February 2014 <19.?> This unique monday involves a help-queen-sac. White's first move induces a Black queen sac, though... it does actually still lose for black. <19.Ng5+> forces a capture on g5. The point is that after 19....hxg5 20.Rh3#, but nonetheless, ...

TheaN: <PB> typically some players seem to overlook 39.Kf1 Qd3#.
 
   Feb-03-14 Kiril Georgiev vs Y Yu, 2013 (replies)
 
TheaN: I do have to add to the notion that this is, at least, a very different monday puzzle than usual. Recognizing a mate in two or three with a queen sac is something else than forcing a rook gain via a promotion combo... would have sufficed as a tuesday puzzle as well, but I guess they ...
 
   Jan-29-14 Wilke vs Priwonitz, 1933 (replies)
 
TheaN: I was not completely sure, but I think I got the majority of the combination covered. For what it is worth, I did notice 16.Rg1 Qh4#, I should have mentioned that. The nasty part for white in this position is that the e1 rook is also weak after the queen goes; otherwise attacking the ...

TheaN: <FSR, erniecohen> Whoops, missed that earlier post (guess it's due to the symbols, I tend to skim them too quick). Guess the underlying ideas of 37....Qxh3 do win after all, albeit being a tad bit more complex than Be3. I do have to admit that I've missed the idea of Qh2! after ...
 
   Jan-20-14 Van der Wiel vs Timman, 1982 (replies)
 
TheaN: Monday 20 January 2014 <28.?> Not much to blue monday: vd Wiel sacs Timman into mate with <28.Rxa6+ bxa6 29.Qxa6# 1-0>. The only reason why someone would be confused here is to start with Qxa6+ as queen sac, losing.
 
   Jan-14-14 K Wallach vs A Kornfeld, 1982 (replies)
 
TheaN: Tuesday 14 January 2014 <30....?> White just condemned his King by blocking f1. Black utilizes a <replace-the-piece> tactic to take control of g2: after <30....Rh2+ 31.Kxh2 Qh7+ 32.Kg2 Qh3# 0-1> the queen covers g2 and white is mated. More interesting is the ...

TheaN: <offramp: <morfishine: 31...Qb3 forks the rooks <TheaN> Nice synopsis> I prefer your synopsis.> Mine is not really a synopsis in all fairness, was just noting the idea e4 could lead to some misleading complications. Not many solvers had mentioned it, so yeah... ...

TheaN: Happy New Year to CG, new year new chances. Starting with a Monday puzzle to get off the bat easily. After <24.Qh7+> white exposes Black to the deadly power of the light squared Bishop. After 24....Kf8 25.Qh8# he covers f7, after <24....Kxh7 25.Bf7#> he shield off g6 and ...

TheaN: Bah that did cross my mind very briefly, to look at a different angle or turn it around. Not that, though.
