|Apr-16-04|| ||chessgames.com: Honza: thanks for all these games. Perhaps you can tell us something about this player. |
|Apr-16-04|| ||Honza Cervenka: Josef Dobias (b. 1886) was a Czech chess master from the generation of Oldrich Duras, Ladislav Prokes, Karel Treybal or Karel Hromadka. He was a good combinative player. |
|Jul-18-04|| ||Benzol: Is his name pronounced 'Doe-bee-us' or 'Doe-bye-us'? |
|Jul-18-04|| ||nikolaas: I think it's something like Doh-bee-as. |
|Jul-19-04|| ||Benzol: Thanks <nikolaas>. |
|Jul-19-04|| ||Gypsy: Very good <nikolaas>. There actually are two diacritical marks missing from the master Dobias (Dobia's^v) name. Thus Czechs actually pronounce it |
Do ... like of do-re-mi
be ... like of honey bee, except short
aash ... rhymes with sash.
|Jul-20-04|| ||nikolaas: Maybe it should be written Dobiáš? |
|Jul-20-04|| ||Honza Cervenka: <nikolaas> Exactly. |
|Jul-20-04|| ||nikolaas: <honza cervenka> I didn't know you're Czech too. Though your name sounds alittle bit Czech-like. Are there still more Czech people here? |
|Jul-20-04|| ||Honza Cervenka: I don't know how many Czech users are here, but Gypsy and Lopin (see User Profile Page ) are Czechs almost certainly. |
|May-04-05|| ||Gypsy: <... IM Dobias was famous for trully fantastic time-pressures; such time pressures where we was forced to make only short moves and, as much as possible near the clock, so that he would not loose much time. But in those time pressures he played well. I faced him once, perhaps still as a junior, and he was again in his severe time-pressure. My position was a bit better and I certainly had the initiative. With a great effort I always conjured some 2-move threat, attacked something, Dobias retreated or sidestepped it, and it appeared that our game would continue like that for all of those fifteen or so moves my oponent played with his flag up. Untill I got an idea to try to go at it differently: At a point where I had some three different "attacking" moves on the king-side -- and moves of the same type, put something under the attack or threaten something -- I interrupted the rhythm of the play by a look-warm move a2-a3. I did not attack aything, I did not threatten anything, I just moved a pawn on the other side of the board by one square. The result was immediate: My oponent had no prepared repply, he stopped to think for a moment and -- his flag fell.|
In a time-pressure a player thinks more about moves than about problems; he just tries to have a ready-made lightning answer for every move of his oponent. The worst is to press the oponent in a time pressure by tiny 1- or 2-move threats. Those are realy the easiest to foil. ...> Jiri Vesely, "Psychological Guide through a Chess Game."
|May-13-05|| ||Gypsy: <Ninety-two years old IM Dobias played his games agains top oposition in the Prague-1980 master tournament very well. Were his games after 3-4 hours of play adjudicated, he would have ended most impressively. But during the fourth and especially fifth hour of play he spoiled a'lot. A player nearing centenial certainly has a right to be tired after five hours of play.> Jiri Vesely, "Psychological Guide through a Chess Game."|

|May-26-06|| ||itz2000: GYSPY it's very easy puzzel!
King kill the solider.. then he goes to step up, and get a queen without any problems, Q+K vs K = easy win.
|May-26-06|| ||Gypsy: <itz2000> That is the general idea. The devil is in the detail. Can you give variations?|
|May-28-06|| ||itz2000: GYPSY?

|May-29-06|| ||Gypsy: <itz2000: ... 1. Kf4 Kc4 2. Kg5 Kd3 3. Kxg6 Ke2 ...> 3...Ke4 draws here; White pawn falls.|
|May-29-06|| ||Honza Cervenka: <Gypsy> Without board it's hard to find precise way to win this pawn ending but maybe 1.Kd4 Kb4 2.f4 with next Ke5-f6xg6 works. At least I see no good defence for black here.|
|May-29-06|| ||Gypsy: <Honza> You are right (though 1...Kc6 gives a stiffer resistance). The point of Dobias' study is that natural attacks, as well as the theory of oposition fail to win the game. Only a precise and subtle maneuver of White king wins:|
I. 1.Kf4? Kc4 2.Kg5 Kd3 3.Kxg6 Ke4! ... =
II. 1.f4? Kc4 2.Ke5 Kd3 3.Kf6 Ke4 ... =
III. 1.Kd5? (oposition) Kb4! 2.Kd4 Kb3! 3.f4 Kc2 4.Ke3 Kd1 5.Kf3 Ke1 6.Kg4 Kf2 7.Kg5 Kf3 ... =
IV. 1.Kd4! Kc6 2.Ke5! Kc5 3.f4! Kc4 4.Kf6 and 5.Kxg6 ... 1-0.
As far as I know, this is the only study by Dobias and it probably is derived from a real game.
|May-29-06|| ||Honza Cervenka: Thanks <Gypsy> for pointing this out. Anyway, it is useful to remember this study and lessons derived from it. This ending or something similar can arise in a game quite often.|
|May-29-06|| ||Mating Net: 1.Kd4!, and similar King moves, are known in endgame circles as the body check.|
|Sep-29-13|| ||Pulo y Gata: No matter how good he plays, people say his games are Dobias.|
|Dec-16-13|| ||senojes: This is in Fine's "Basic Chess Endings," revised by Benko (2003), page 13, No. 18. Houdini 4 confirms that only 1.Kd4 wins, and BCE says that 1.Kd5 and 1.Kf4 draw. It doesn't mention 1.f4 but 1.Kd5 transposes into it.|
|Dec-16-13|| ||DoctorD: Its a tablebase position, so no need to ask Houdini. As for "body check," I think GM Mueller was the first to use this phraseology.|
|Dec-16-13|| ||DoctorD: There are some other types of problems by Dobias in the databases, this selfmate is interesting:|

You have to find the square from which the white queen will make its next move, either to check and force mate or to get out of the way and allow a ZZ mate.
