That's a fascinating article. Bridge cheating seems quite quaint. No computers, just hand signals.

Sep-28-15  savagerules: A few years ago a couple of high ranking german bridge players cheated by having one of them cough at certain points in the bidding, which is mainly when the game is won or lost at top levels. Apparently a soft cough meant one thing and a louder cough meant something else etc.
Oct-24-15  PJs Studio: There is a simple way to test if Ivanov is a cheater (although it looks as though he was near proven as a cheater):

Anyone who can beat a grandmaster can play damn good speed chess. Have him take on a 1900 or 2000 rated player. If that player can beat Ivanov (without his special shoes on) there is NO WAY IN HELL Ivanov can beat multiple 2500+ GM in consecutive events.

Oct-24-15  PJs Studio: Also, I'm from the west (NY,MA,VT area) and in such a conservative and educated area, only a total looser! would use a computer to even glance at a position on a smart phone. Total toilet move!

If he was cheating he should be deeply ashamed of himself.

  Fusilli: <PJs Studio: Also, I'm from the west (NY,MA,VT area) and in such a conservative and educated area...>

Eh... <west>?

And <conservative area>?

Oct-24-15  Howard: I lived in Connecticut for two years and never really considered that state to be in the "west." Probably no one else out there did either.
Oct-24-15  zanzibar: Well, if you lived in Maine you'd consider Connecticut a western state.

Just like in Boston we consider Pittsfield a western town (city).

Premium Chessgames Member
  Fusilli: <zanzibar> Well, yeah, all is relative, and I live in East Nashville, but would never say to a general audience that I live in the east. The statement would only make sense if I were talking to someone here in Nashville. I am inclined to think that <PJs Studio> meant to write east, or even north east?
Oct-24-15  PJs Studio: The whole of the United States is in west! - I was speaking of America. Which is how the term "west" was used here (see above) the rest of the world say west for Western Hemisphere. No question!

2. This is not a US website. Lots of Europeans.

3. North of NYC northern NY becomes about 70% hardcore FOX news watching republican. Not me, but I'm surrounded on all sides.

4. True. NYC is liberal... I'm in the MA VT NY area. Where the boarders converge. Being moderate around here is dangerous...forget about democrat. Oy!

Oct-24-15  Fishy: Borislav, a cheater or a revolutionary?
Oct-25-15  PJs Studio: Cheater

  offramp: <PJs Studio:... only a total looser! would use a computer... >

What is a looser?

Premium Chessgames Member
  perfidious: <offramp> The opposite of a tight player, of course!
Oct-25-15  Fishy: lol...that was great <perf>
Oct-26-15  PJs Studio: Offramp- it's a colloquialism from where I'm from. Slang for "dead beat, bum, woman beater, slow witted..." It's got a lot of uses.

Obviously I meant if he uses a computer DURING AN OTB game. I use machines for Schach as much as I can, but OTB I turn my phone off and leave it in my pocket. Grossly unfair to check analysis at a critical point.

  offramp: <PJs Studio: Offramp- it's a colloquialism from where I'm from. Slang for "dead beat, bum, woman beater, slow witted..." It's got a lot of uses.>

It sounds to me like you meant "loser".

Looser means "more baggy".

Oct-27-15  galdur: Guy 1: OMG! Todd is such a looser!

Guy 2: I told myself I was going to do this do the next person I saw spelling the word "loser" like that; so now I am going to set your house on fire. You brought this upon yourself.

Oct-29-15  PJs Studio: I catch others typos rather quickly. My own, not so much.
Premium Chessgames Member
  Domdaniel: <Looser means "more baggy".> So it does. Just who do these baggiers think they are?

<Draw, Loss'n'Tie> is an anagram of Andrew Soltis. Spooky or what?

<PJs> Um, you mean "others' typos", no?

Nov-07-15  Amulet: <Fishy: Borislav, a cheater or a revolutionary?>

He is a disgrace to our chess patron Caissa!

Nov-08-15  PJs Studio: You are very Incorrect. I meant "other's" - which is a small oversight on my part. But your others' is an enormous oversight on your part. You are correcting me incorrectly and you have the Internet at your disposal.

For shame Amulet

Premium Chessgames Member
  Domdaniel: <PJs Studio> I'm sorry you think <others'> is an enormous oversight. I still think it is correct, but it's possible that I'm wrong. I'm not really a pedant, despite appearances.

I quite like your bio, btw.

  Domdaniel: As some Irish dairy farmer once said: "I owe my success to udders".
Premium Chessgames Member
  Domdaniel: This page still has a link to "FIDE Player card for Borislav Ivanov" ... but it leads nowhere, as there is no such FIDE card.

  whiteshark: Christof Sielecki with White vs a (probable) cheater 5...4...3...2...1...

You can 'smell' the cheater panicing when his time is trickling off.
