Member since May-15-05 · Last seen Jan-19-17
Since 2001, I've play skittles chess (5 minutes + 3 seconds) on I always make my own table, and sit down as Black (so my opponent starts with White). My username starts with "Gilmoy", and the remaining 10 letters is whatever inane or topical joke strikes my fancy. I play from newbie (1500) to red dot (2001+), then retire the account and make a new one; I have over 70 (most of which have long since expired). My best performance was 71-4; my worst take well over 400 games. Pogo e-mails you a PGN of your game on conclusion (if you ask; I always do), so I have them all archived.

I have no offical rating -- I've never played in a tournament (nor even seen one in person). My schedule never permitted it, and I suspect I lack the patience for tourney time controls.

I learned the moves almost 30 years ago, from books. My favorite was Cozen's "The Kinghunt in Chess", which I haven't seen since. I was hooked on the beauty of chess -- I knew Immortal, Evergreen, Rubinstein's, Fischer's GotC, etc. I didn't know how to actually *play*, though.

I played with friends in middle school, and had no clue. Later, I briefly (like, twice each :) attended the chess clubs at Caltech, U.Illinois (Urbana-Champaign), and U.Wisconsin-Milwaukee, but they both preferred flat 5 minutes, and I can't think that fast -- I need the 3 seconds.

In late 2006, I started solving's Puzzle of the Day. After a few months of that, my play on pogo has gotten somewhat more vicious, and much more fun. I look for piece sacs that I never would have considered before. My opponents have declined about 80% of them -- even the unsound ones ^_^

I prefer Ruy/Spanish as White or Black. As Black, I trust my QGD against 1.d4, but I dabble in KID, QID, or Nimzo-Indian -- usually whichever one I saw most recently on at super-GM level :) I used to lose to King's Gambit more than any other opening by White, until I got mad, Googled it, printed out the first 3 hits, and did some homework. Since then, my KGA is about +350=10-20 as Black.

I like watching soccer and volleyball. I prefer informative TV like Discovery, History, A&E, piano/violin concertos, Broadway musicals, animals of all kinds, and YouTube videos thereof. I found a male praying mantis (~3 cm long) in my dorm hallway once, brought it to my lab in a Tupperware, and took it hunting for mosquitoes every few hours for a week. Mantid poop looks like compressed mosquito shell fragments.

In real life, I have feathers and a beak. Chirp chirp!

Gilmoy: After <An Englishman>'s line, we have: [DIAGRAM] And White is one tempo short: 45.e8Q <isn't check> Qh4+ forks f2. Black can capture either way and still have a Q-R mate pattern.

Gilmoy: On the plus side, at least White's QB isn't a <bad Bishop>. After <30..g5 31.Kd3>: [DIAGRAM] it "forces" <31..h6>. Thereafter, it valiantly prevents the passed h-pawn from running! Black's pawn structure was weak on the white squares. Yeah.

Gilmoy: 23..Rxe6 24.Bxd5 and Rc8 hangs on the pin. 24..Kf7 25.Qxf5+ wins a rook. (Black's K-side pawn structure is really bad against the Qf5 threat.) Black's best is probably to return the rook immediately, but all ways lead to problems. 24..cxd5 25.Rxc8+ Bf8 26.Qxf5 Rf6[] 27.Qxd5+ Kh8 ...

Apr-14-08  mistreaver: I'll give a shot at your puzzles.
1) I think that Bf5 is the solution as it stops the f pawn from advancing and thus keeps h6 square for rook. 2) I kept looking at this but couldn't find anything

  Gilmoy: "Solution" (such as it is) to [p.1, kibitz 2], GilmoyEatsASalad - Tenor89P, which see.

<At 12.e5 I was already envisioning the sac. This pawn thrust has two points: (a) boots out the stalwart Nf6; (b) clears e4 for a K-side swarm, e.g. Ne4, Q sideways, and possibly the b1-h7 diagonal. Black usually must struggle to prevent this!>

13..Nc7 <threatens Nb5>

<I saw that the immediate 14.Ne4 momentarily impedes my Q, after which 14..Nb5 drives her off, winning the e-pawn. So I wanted to move my Q first, without losing the pawn. Including time for the sac itself, I spent almost a minute on:>

14.Qf4 b5 15.Ne4 Bb7 16.Nf6+ Kh8!?

<I calculated that gxf6 17.exf6 isn't winning -- Black has time for Kh8-Rg8. I vaguely planned c3-Bc2 and a rook lift for pressure against h7. But having spent almost half my game clock preparing the sac, I was determined to have some fun!>

17.Rd3 <Now my N is safe (proof thereof is roughly Tuesday level)> Nd5 18.Bxd5 Bxd5 19.b3 Rac8 20.Rh3 g6 <20..h6 21.Rxh6+ and Q mates> 21.Rxh7# 1-0

<Black surprised me by declining the sac. It led to a slow-motion Arab mate, but I think after 17.Rd3 White is winning anyways. It's a fringe benefit of looking for outrageous sacs -- sheer aggressiveness can rattle your foe.>

<Like most other chess enthusiasts, I've gawked at Rubinstein's Immortal. One nugget I mined from it was a deep appreciation for King-in-the-corner. The canonical form has a B covering g1, as here, which implies that White's f-pawn moved. It can arise from the outright check Bc5+ Kh1. Rarely, White plays Kh1 specifically to unpin his f-pawn -- dangerous because he's inviting this mate pattern.

Here, I realized with compounding amazement that White has one fatal weakness -- he can't double anywhere along the a7-g1 diagonal in one move. That means he can't stop my B -- only spite-block to delay mate. But how to get a line-moving R to h?>

18..Bf5! <mistreaver [reply 16] is correct: the point is to blockade f4, so that White's B cannot control h6.>

<White has two spite-blocks on the diagonal before Rh6#. Later, I realized that 18..Rxf5 works just as well. So I had no reason to decline that pawn. Hence, 18..Rf6 was a bit theatrical.>

<OK, he's down a pawn, and his hapless Nd4 is pinned and outnumbered 4-3, so it's toast. The only question is which piece I want to end on d4. Rote application of minimal cost suggests ending with Rxd4, which wins NN(+B) for R(+B) and boots his Q out -- but after that, it's blah.

Much more exciting was to hammer the King-in-the-corner syndrome, and end with Bxd4 -- a subtle fork, Ra1 and g1. What I saw "in a flash" was the Greco sac -- which is matish if I own g1!>

During the game, I thought my whole combo was "silly" because it relied on White reflexively saving his Ra1 -- perhaps he could have refuted it by elegantly returning an exchange, and doing something on the K-side? But on hindsight, I think he doesn't have any such move! My Bs are just too, ah, "rubenstian".>

  Gilmoy: <newzild> wrote in Gurgenidze vs A Lein, 1966, kibitz #22: <Gilmoy: In your skittles game, instead of 29.Rg5, why not just play 29.Rg3 and 30.Rh3?>

You're right, both lines win -- in fact, 29.Rg3 mates 1 move sooner. I saw 29.Rg3, but I preferred 29.Rg5 for five reasons:

1) Sets a trap -- Black could lose instantly.
2) Burns some clock -- Black must think a bit to avoid #1.

3) Complacency -- Black might think he's safe, and miss the second threat.

4) Practice -- In future games, I probably won't have the luxury of two ways to win, and I'll need to be able to (see and) calculate a sac line. I had already invested the ~20 seconds to work out the sac to mate, so I decided to have some fun. (Also, I enlisted his help to double-check my work!)

5) Prettier :)

"... Replace costly computation with fast pattern recognition. ..."

How did you do it?!!

Premium Chessgames Member
  Gilmoy: <johnlspouge: ... correctly spaced list on consecutive lines> I don't. It automatically line-wraps some of them, and not others. I don't know how it decides.

I just keep previewing and editing to manually insert newlines wherever needed. Very annoying.

Sep-13-11  Shams: <Gilmoy> What do you play against the 3.Bc4 King's Gambit, may I ask?
Premium Chessgames Member
  Gilmoy: <Shams:> 1.e4 e5 2.f4 exf4 <3.Bc4> Nc6 and then try to transpose to the following.

The usual line is 3.Nf3 g5 4.Bc4 Nc6 5.d4 d6 6.O-O Bg7 7.c3 h6, and Black plans Ne7, O-O, "with a Swedish Defense" (except that I've never heard of a Swedish Defense in any other context). If White deviates, I freelance.

Fish in my waters are generally confuddled by a non-Muzio positional grind, and sometimes trade away all the tension, esp. with an early e5 without support. I used to feel that KGA should produce a KID-like pawn storm, but that never works.

The 4.h4 g4 5.Ne5 Be7 line is the biggest test of my limited study -- it goes to about 12, with a Bxh4-Bg3 for Black, and White's Nc3-Nd1 covering the pinned Nf2. After that, I dunno: insufficient data!

Jan-30-12  Shams: <Gilmoy> Loved your M:tG reference. Unrepentant geekdom is celebrated where I call home.

<KGA> I would imagine 3.Bc4 Nc6 you see 4.d4 a lot. I would play it instantly.

The King Hunt in Chess

Sep-21-13  waustad: Nice avatar. Is this you dancing?
Mar-31-14  waustad: < My schedule never permitted it, and I suspect I lack the patience for tourney time controls.> This really is an issue. Many years ago I played tournaments after some years of playing blitz in the bar and found it difficult at first to spend enough time to analyse the position. After about a year I got it together and my rating jumped. I was already way too old to get very good, since I was well over 30 then and hadn't taken chess at all seriously until Fischer vs Spassky when I was 22, but tournaments are a very different game. They are fun and I'm thinking about doing them again some time. It would be a good excuse to do some travelling again.
