Just a theory...

Thoughts literally overflow my mind. It's hard for me not to think about stuff. Some are more intellectual than others. I think about unsolved mathematical olympiad problems in canteen queues, I think about flaws in my bridge bidding system, I regurgitate facts which I just "memorised" from my lecture notes, etc.

Some are, well, less intellectual. Or may I put it in a more euphemistic way, fantasies. Yet, the trips in the azure of dreams is no less productive than my thoughts in other departments. In fact, I would go as far as saying that it defines how I act, how I talk, and how I interpret the intriguing social happenings.

And yes, these are childish fabrications, utopic yet motivational. True enough, I feel shameful to admit this in front of the public. Who wouldn't? And what better place can I share these enchanting thoughts unabashedly than this silent blog?

When I am showering, I picture myself as a cover image on the Time magazine, probably posing with a solemn face with an air of academic condescendence. And for what reason should thy face appear on the veneer of the publication? Probably for winning a gold medal in IMO in Primary School? Or perhaps conquering the perfect score which every Math Olympian can only dream to achieve (which ironically, is what I am doing right now)? Maybe take this littlun to a stage of a momentous speech? A speech that will grant him a Nobel Prize? and slap on 4 years of presidency?

As for the social aspect, maybe the beginning can be humbler. This littlun should be eking out a life for himself. Maybe start by selling the best wanton noodles in the town, and then miraculously discovered some mathematical olympiad books which provokes the prodigy in his mind. And at the end of my life I have a great deal of inspiring story to talk to my kids. And suddenly my roommates just have to switch off the heater and make me realise that I am in reality.

But I do realise how these thoughts have affected me. You see I come out with a lot of theories of how the society operates when I am simply doing nothing else, like walking from the college to the boarding school. Among these theories is one which I am particularly convinced that it models our society very well. And it comes inadvertently from all the ideals which randomly sprouts out of my head. I will feel guilty if I don't pen this idea anywhere in the world.

I believe that everyone has an ideal world which resides in their mind. Figuratively, think about the Plato's cave, in which everyone is tied to the chair and forced to see every scene which flows through their eyes like a movie. But not everyone likes what they see on the screen, simply because they are EXPECTING what will happen in the "movie". They expect themselves to have high achievements, they expect themselves to be understood by others, they expect lady luck to be kind to them. These expectations are the IDEAL world to them.

But back to the real world, not everyone has the same concept of an ideal world. A phrase like "what's wrong with you people" may be a joke in one's ideal, but it hurts in other people's opinion. When one achieved good results or won a competition, it infringes another person's ideals and jealousy will stem from there.

It's really interesting how this model describes the world. By using this model, it suggests that the kind of person who survives the best in this world is a person who can manipulate his ideals to complement the ideals that other people have. Kinda sounds like a hypocrite, but apparently that's the secret of the society. Game theory teaches us that the TIT FOR TAT strategy is the most robust strategy that sustains cooperation. In what ways are TIT FOR TAT not hypocritical then?

Well, most people would have lost me by now. I would be surprise if anyone follows up with my arguments, he/she must have the same ideals as me...

_______________________________________

I miss being small. Not in the figurative sense, if you know what I mean. (whatever I don't care if you don't XD) Why? Because people will listen to your theories to appease you, even though they think that you are crapping. You have to be much more credible in what you say when you grow up.

Which sometimes pisses me off when people expect me to know a lot of things because I appear to be smart. I seem to be able to get good grades, but really don't put too much expectations on me and give me the dubious look.

Ok that's not important, I can cope with that. At least people values me :)

But not everyone gets appreciated that much. Even though they are way smarter than me.

Anyway, this guy whom I am referring too. I realise (actually I realised very long ago but for the drama effect I will stick to present tense) that I have too many similarities with him.

For example, I almost wasn't able to go to Las Vegas because of some discrepancies with my US Visa. And for the freaking same day (which haunts me after I read this person's blog), this person was also having problems in applying Visa (to China). ON THE SAME FREAKING DAY RIGHT BEFORE SMO. We both solved our problems, but with different sentiments.

The moment I receive my passport I was so grateful and proud of myself. I was grateful to the the buddha whom I have prayed to. I am proud of myself for doing this mostly by myself, taking the initiative off an afternoon which I was supposed to be studying. I am proud of myself for saving the money of the trip for 3 people.

But he blames the school admin for not informing him to apply for visa. Just put it in comparison. His blogskin is black, mine is white. So similar yet so different huh.

And from recent posts he still sees me as a rival. I probably see him as a rival too 2-3 years ago, but the immature years have passed. I now do things for the sake of myself and not for the sake of other people.

It really hurts when I realise that someone hates me so much, just so you know...

A Weekend of Good Bridge

I was kibitzing the J1 team match against SCBA(B) for Bridge League Cup yesterday. Despite the fatigue due to H3 Econs exam, it was still a worthwhile journey because of all the interesting boards that came out during the match.

The first board that I want to discuss concerns accurate defense. Both declarers in NS made 3S, making it a push board. At the table that I was kibitzing, the bidding went as follows:

W N E S
1S
/ 1NT / 2S
/ 3S //

Nothing interesting. West was holding the following hand:

Jxx
Jx
AKxx
Jxxx

In this case, the choice of suit to lead is very obvious. West should lead the king of diamonds to ask for the count in the diamond suit (Attitude is pretty useless here since declarer is likely to be short in this suit as he has shown a long spade suit. It would not matter if partner held the queen of diamonds). Dummy was laid:

Qx
AQTxxx
xx
Q9x

East followed small, declarer followed small. How should west proceed?

The key to finding the killing defense is to count. In this case, the switch to club is called for. Of course, many people would reason that a club switch is obvious just by gut feeling. Before reaching this conclusion, have you considered to cash another diamond trick? Have you considered to play a heart in hope that your partner holds three hearts to the king and ace of trump so that you can attempt an uppercut? Even when switching to clubs, have you considered whether you should play the jack of club of small club?

East hand was as follows:

xx
Kxx
QJxxx
AT8

Declarer was holding:
AKxxxx
xx
xx
Kxx

Lazy to type out my reasoning on how the defend should go, welcome any responses through comments.

___________________________

The following deal illustrated how one should not feel despaired even though the contract is hopeless. One should still keep calm, concentrate and calculate the best plan to catch a sleeping defender:

x
KQxx
xxxxxx
9x

Qxx

KQJxxx
AQ7

South was the same player as the above previous deal. He was playing in a 5D contract missing 3 aces. West led the jack of clubs from a JT sequence, east encouraged with 8 and south won with the queen. The first plan was to steal a trick in hearts. West correctly rose with the ace of heart. Encouraged by his partner, he led the ten of clubs, which is perfectly fine since he is still unaware of the position of the ace of spades and he has the ace of diamonds. The problem arise when east, out of unknown reason, covered the ten of clubs with the king of clubs. South was a sharp declarer. Despite facing a level 5 contract without any aces, he was able to identify 7 as the largest available club. Of course, he used this to discard the spades and the rest of the story is irrelevant.

Moral of the story: Even in hopeless situation, do concentrate, be calm and count!

Hope the J1s learned their lesson the hard way.

____________________________

I learned some lessons during the Sunday team matches today too, just that I was lucking as my mistakes did not cost. The first error occurred when I was holding this hand:

KJTxx
KJTxx
Ax
x

My partner bid 1S. I splintered with 4C. Partner bid 4H showing first round control in hearts, I asked for keycards and landed in a 6S. The 6S made because of defensive error by the opponent. Yet, it was a good slam.

The problem lies in the bid of 4C. At that moment, I considered that so long my partner has an opening hand outside his club suit, we have a high chance of making slam (which is indeed what is mentioned in Ron Klinger’s book “Cue-bidding to Slams”. What I failed to consider was that even if my partner has an opening hand outside the club suit, the contract would fail if his points are too concentrated in the diamond suit. Consider the following hand opposite my hand:

AQxxx
xx
KQJx
Ax

6H can still make, just that it is much more unlikely. You need the ace of heart to be onside. Many people recommend bidding to a slam that makes on a finesse. I prefer to go against this belief as a lot of IMPs are lost because people enjoys the thrill of slams and tends to overbid.

The point is, I wouldn’t be able to ask partner for a heart control in the event that my partner bids 4D instead of 4H. A more creative approach is to bid 2H (game forcing) after the 1S and explore the slam slowly via principal of fast arrival.

__________________________

Moving on, a partial contract, but no less interesting. I was holding:

Kxxx
Kx
QTxxxx
x

Partner opened 1NT. I bid 2C (Stayman), partner bid 2D, and I bid 2NT. Partner passed and eventually we made 11 tricks.

Bidding 2NT was an amateurish mistake. In this case, 3D is the correct bid. 3D offers a safer contract for partner to land in. Most importantly, partner can find a 3NT with minimal game points when he has Xxx in diamonds (which in this case, he has). In addition, he may opt to play in 5D if he deem 3NT as dangerous with maximum. Another instance of a lack of experience and creativity...

___________________________

One final mistake before I sign off...

Axx
AKQxx

I was in the third seat and went “wow” when partner opened 1NT. I transferred to hearts and bid 4NT. 4NT!! I can’t believe I bid that on the table. Likely because I have never actually bid this kind of hand in my life before. So what is the correct bid?

The correct bid is to fake a 4 card diamond suit by bidding 3D. When partner bid 3H, you can proceed with all your sophisticated slam bidding tools. When partner bid anything else, you can sign off in 6NT. Either way, abusing 3D does not cost.

On a side note, my team got another honorable mention in the Purple Comet Math Meet, just by 1 freaking point again. 28/30 what the hell, this kind of error-prone question is just not my cup of tea zzz

A Common Mistake

There’s one particular type of mistake that occurs rather frequently. Many people, myself especially, tends to only approach a problem from a direction. Even when checking the answers, many did not consider the possibilities of solving the problem through other means. As such, many errors are overlooked.

This kind of error is critical in almost all aspects. Annoyingly, such careless mistakes is often disguised under the veneer of a self-perceived “superior working”. Here’s a hand that I held on BBO.

S Axx
H J10x
D xx
C KJxxx

Not a very interesting hand, especially after hearing a 1C from the dealer on your right. I passed, LHO passed, and my partner bid 1D. The bidding went on as below:

S W N E
1C
/ / 1D /
1NT / 2S /
3NT //

Expecting a dummy with 16-17 hcp, 3NT was not a hard decision. Dummy was

S KQxx
H Qx
D AKQ109x
C x

West led a small heart. After east cashed the ace and king of hearts, all followed small. East then returned a small heart and a club is discarded from the dummy.

What is the danger? It is not hard to identify a safety play often described in books. The risk is that west may be holding 4 or more cards in diamonds. If diamonds were to be cashed from top, you have to surrender a diamond trick to west and he will cash 2 heart tricks. As such, the safety play is to finesse the jack of diamonds (one should finesse directly instead of cashing a top honor, which will fail in case of 5-0 split). It is almost impossible for west to have an entry since east opened, which most likely leaves west with no more than 3 HCP.

So yea, luck favors me and the finesse worked. At this moment the error occurred. Can there be any error when all you have to do is to cash your top tricks?

It turned out that there was an automatic squeeze in clubs and spades. At that moment, I simply cashed the spades to check for split without cashing the diamonds! As a result, I missed an overtrick (and a chance to satiate my ego ><)

Such errors may mean nothing to many people. Sadly I am unable to tolerate such mistakes. Blame me for being a perfectionist. The fact remains that people judge you by the errors that you make and the resultant outcome. I have been so irritated by all the careless mistakes I made, be it in Math Olympiad, Chemistry and Physics Olympiad, Bridge, common tests, etc etc etc. It’s really heartbreaking to think that you have arrived at a splendid solution to a problem, yet a careless mistake such as calculation error undermine your efforts.

Missed a chance to win an iPad today... I guess I will have to blame my carelessness again.

A fallacious deduction

Played this board yesterday in SCBA:

Kxxxx
Kxx

Q82

AQxxx
Ax
AQx
Axx

Bidding went
p - p - p - 2nt
p - 3H - p - 4S
p - 4NT - p - 5C (1 or 4 keycards)
p - 6S - ap

This is a make or break contract as I was playing in MP. Most people in the field will play in 4S, either because South does not super-accept or north fear that a slam is too anti-percentage. As the cards lie, it seems like the slam is only making on 2 finesses.

Fortunately, opponent led a diamond 10. So it all boils down to the club play. I drew trumps and stripped the hands to arrive at this position:

Q82

There are two possible lines of play from here: either cash the ace and play towards the queen, or play small to 8 and endplay east. The former will work if west held the king and the latter will work if east held the king. Thus far, west has played 4 hearts, 1 spades and 4 diamonds while east has played 4 hearts, 2 spades and 3 diamonds.

Figuring that a singleton king is to rare to occur and cashing the ace will void the endplay, I played small and west followed with a 3. I took some time to think and eventually played the queen. The king was onside and I made the 6S and this deciding board scooped us a 1st in the event. Why queen? Why not play 8 and endplay east? My reasoning on the spot was west could have played a spot card larger than the 8 if she did not hold the king of club. This will prevent her partner from being endplayed. However, she played the 3 nonchalantly, suggesting that she did not have such concern and hence hold the king of clubs!

Such deductions are subtle but gratifying. However as it turns out, west did not even have a spot card larger than 8 :( My deduction was, to a large extent, fallacious. I guess this is just a small step in improving my declarer play...
I have had a secret blog for some time already. I used to post on the blog when I am depressed, when I feel discriminated, or simply because I have a bizarre view on some aspects of life. It was no surprise that the blog eventually turn out to be an extremely wretched site.

I am going to start a new blog now, mainly focused on what I am passionate in and what I cherish for the past few years. Hope it goes in the right direction :)
