<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: Perhaps the most interesting display of dominance is 22.Re4 Bb4+ 23.Rc4 Rfe8!?. Okay, Qxc4+ is best, but now 24.Rxc7 Rxc7+ and mate in three.

TheaN: Monday 18 May 2015 <17.?> White's a piece up, but gladly returns it with <17.Nf6+> with <18.Qh7# 1-0>. I guess a rating of 1100 does explain black's play. In case I agree with BOSTER: all within perspective, so is this puzzle. Bad game, decent Monday puzzle. CG ...

TheaN: Whoops. I did look at Nxg7 and Nh6+ which both seem to win but aren't as convincing, and because of that decided on the sketchy 34.Nd7?!: this is suboptimal after 34....Qd7, now 35.Rh6! still wins but if you don't see the pattern at all, white has a tough game after 35.Qg6?! Nf8!

TheaN: Monday 11 May 2015 <28.?> The finish of a smothered. It is unlikely to have started with a double check seeing how compact black's position is: I see no option for the Nh6 to have reached f7 before. Now, <28.Qg8+ Rxg8 29.Nf7# 1-0> it ends the game. It's almost surprising ...

TheaN: Thursday 7 May 2015 <35.?> Of course white promotes and wins the bishop for two pawns with <35.f4+ Kxf4> alternatives aren't better <36.c6> with <37.c7>, <38.c8=Q Bxc8 39.Bxc8>. However, the endgame itself is not a trivial win, but I'd say that's out of ...

TheaN: More interesting, even if Bxe7 was possible it still wins, lets say we play 30.Rh4 Ba3: [DIAGRAM] <31.Qxe7+> definitely not the best move, but <31....Bxe7 32.Rh7! Kc6> trying to repeat with 32....Kd8? fails: 33.Rh8+ Kd7 34.Bxe7!, if 34....Kxe7 35.Rdh1 Kd7 36.R1h7+ Kc6 ...

TheaN: Tuesday 5 May 2015 <64....?> Dutch liberation day. Black liberated himself from this endgame by trading rooks with <64....Rxc4! 65.Rxc4> else Rxb4 <65....d5+ 66.Kd3 dxc4+ 67.Kxc4> and now just about any move ...

TheaN: Monday 4 May 2015 <23.?> Typical Monday <23.Qxh6+ gxh6 (Kg8 24.Qh7#) 24.Rh7# 1-0>. And I agree with <Once>, black demolished his own defensive prospects by playing 20....Rxf1+. File control can be tricky, but in this case black surrenders it without a fight. It ...

TheaN: <Funology: IMO if you didn't see ...Qd4+ and ...Rb5 and how White should meet it, you only solved half the puzzle. Seeing the Qxf7 mating idea is just the beginning.> Though I agree with that, the combination after 25.Rh8+ Kxh8 26.Qxf7 Qd4+ 27.Kg2 Rb5 28.Qxg6 Qxg6 is ...

TheaN: There is a considerable difference in the potential of Qxh2 with Qe5+ if white plays Bxd3 or fxe3: after fxe3 as in the text the e-file is blocked and black threatens Qxe1+ after Qxa5: that's why in the game Qxh2 doesn't work: Qxa5
