hehe suffer youngster! :P

BTW this tournament, as it happens in other cases, can be considered too ... Tasmancentric?

David Small donated his entire first prize and a book to the junior prize fund and Tony Sturges donated $50. As a result prizes were awarded for =1st junior (Vince and Barnes), 3rd junior (Brown), 1st female junior (Perera) and best performances by newcomers to adult chess (Fargher and Payne).

Most of the seven adults competing ran into junior troubles at some stage of the day and a prime example of this was, er, me, lucky to escape with a draw against Bradley Vince. After I grabbed a couple of pawns Bradley mounted a king-side attack that proved far more dangerous than it looked, which included leaving a knight en prise for a very long time and also sacrificing the exchange. My position got so bad that I returned a full rook (in two hits) to bail out of it while I still had time on my clock. I then had two or three pawns for a piece but it didn't stay that way for long and I would have lost had Bradley not finally run out of energy after I bailed his king up against the side of the board with king and rook.

Earlier Bradley had been very impressive in converting a slightly advantageous knight ending against Michael Midson.

As some people may have noticed a number of the Tassie rapid ratings are still silly but we are trying to fix this by feeding them more data. :lol:

Is there a chance that Bradley Vince is a poofteenth underrated?

Kevin Bonham

The game I had with Bradley went something like this (I'm white). A bit of an epic fail on my part as I actually had lots of safe wins and picked the one way of defusing his attack that actually didn't win. But that happens when you're short of time and under fire sometimes.

1.c4 e5 2.g3 Nc6 3.Bg2 Nf6 4.Nc3 Bc5 5.d3 d6 6.Nf3 Bg4 7.0-0 h6 8.a3 a6 9.b4 Ba7 10.Bb2 0-0 11.Nd2 Qd7 12.b5 Nd4 13.Bxb7 Rab8 14.bxa6 Bh3 15.Re1 Nf5 16.Nce4 Nh4 17.Nxf6+ gxf6 18.Bc3 Qf5 19.e3 Rxb7 20.axb7 c6 21.d4 d5 22.c5 e4 23.Qe2 Kh8 24.Rf1 Nf3+ 25.Kh1 Rg8 26.Rg1 Bb8 27.Ba5 Kh7 28.Rac1 Bc7 29.Nxf3 exf3 30.Qc2 Bxa5 31.Qxf5+ Bxf5 32.g4 Be4 33.h3 Rb8 34.Rb1 Bxb1 35.Rxb1 Bc7 36.h4 h5 37.gxh5 Kh6 38.Kg1 Kxh5 39.Kf1 Kxh4 40.Ke1 Rg8 41.Kd2 Rg2 42.Rf1 Kh3 43.Kc3 Rg8 44.a4 Rb8 45.Rb1 Ba5+ 46.Kc2 Kg4 47.Rg1+ Kf5 48.Rb1 Ke4 (and white is lost but eventually managed to draw)

I think Bradley's rating comes mainly from games played at the Aus Junior over a year ago. The Aus Junior being what it is, 300-ish there is probably worth 800 anywhere else, and until this tournament I would have said he was now about 1000 strength. Today he stepped up a few notches.

Good to see 20 people playing :clap: :clap: .I don't think I've seen an upset result with a bigger disparity between two players before - Bonham-Bradley was nearly 2000 points :eek:

Speaking of junior troubles, I'm currently drawn against Karl Zelesco in Rd 1 of the Doeberl Cup. If I lose the ACF rating system will probably dock me 50 points - never mind he beat two IM's recently - he's still under 1700 :lol: Of course this will be added to the 40-50 points I'll lose for winning the Tassie Ch'p with +4. By the end of the Doeberl I might be in the 1800's :rolleyes:

Maybe Tasmania should invent its own rating system where senior vs junior results get treated differently than other results ;)

Kevin Bonham
16-04-2011, 10:01 PM
Zelesco actually went up to 1873 in the last list and with his great performance in the Melbourne champs his rating may well go up bigtime again so his intermediate rating will be higher. I'm guessing the system will treat him as about a 1900-1950 player for the purpose of his game against you. Still too low but not as bad as it treating him like a 1600s.

Kevin Bonham
16-04-2011, 10:11 PM
By the way I put Bradley's rapid result from today into Barry's Glicko-1 calc plus his current open rapid results and it projected his rapid rating would go into low four figures.

Kevin Bonham
16-04-2011, 10:38 PM
Small - Bonham went something like this except the move order at the start won't be too accurate:

1.c4 Nf6 2.Nf3 c6 3.g3 d5 4.b3 g6 5.Bb2 Bg7 6.d4 0-0 7.Bg2 Nbd7 8.0-0 b6 9.Nbd2 Bb7 10.Qc2 Re8 11.e4 dxe4 12.Nxe4 Qc7 13.Nxf6+ Nxf6 14.Rad1 c5 15.d5 e6 16.Be5 Qc8 17.Qb2 Nh5 18.Bxg7 Nxg7 19.dxe6 Nxe6 20.Rd2 Qc7 21.Rfd1 Rad8 22.Qc2 Rxd2 23.Rxd2 Rd8 24.Rxd8+ Qxd8 25.Qd2 Bxf3 26.Qxd8+ Nxd8 27.Bxf3 Ne6 28.Kf1 Nd4 29.Bd1 f5 30.Ke1 Kf7 31.Kd2 Kf6 32.Kd3 g5 33.Ke3 Ke5 34.f4+ gxf4+ 35.gxf4+ Kf6 36.b4 Ne6 37.a3 Nd4 38.Kd3 Nc6 39.Kc3 Nd4 40.Kd3 Ne6 41.Ke3 Nd4 42.Kd3 -

David had the option of playing d6 if he wanted to have a go at beating me but with Tony Sturges clearly winning against Vince on the adjacent board a draw was sufficient for him to win the tournament (or he may not have been completely convinced that it was safe!)

Kevin Bonham

Sturges - Bonham. Tony's only loss as he was one of the two adults to escape "junior trouble".

Hi Kevin, First thanks for organising a great tournament. Thanks also to Melissa for all that she does for the juniors. I was really impressed with the number of juniors and the quality of their play. Some of them showed really maturity in the way they handled the seniors. There is some real hope for the future. We just have to keep them keen...

Yes, the opening move order is not quite right (as you guessed), but the final position looks correct. I recall that both sides rooks were further developed when Be5 was played. It was about that time that Tony looked to be winning and all I needed was a draw, so I played for a few exchanges. The endgame has some interest due to the N vs B imbalance. When I went for all the exchanges, right near the beginning, I was a bit worried about the possibility that the endgame (after Bxf3) might be very difficult for me as the N looked as though it would dominate the B. But I thought it was worth the risk.

Hopefully if my work schedule allows, I will be able to make it to the Open in the middle of the year. Thanks again and congratulations to all the prize winners.

David

Thanks Kevin, I 'misremembered' (to borrow a verb from American politics) Zelecso's rating fom the Doeberl site. Not that I really care about my ACF rating though.

Is there a chance that Bradley Vince is a poofteenth underrated?

As a sign of how quickly Glicko can come to the rescue of a rating that is clearly complete rubbish, his new rapid rating is 1077?? Even that may seem low given his performance in this one but in the other rapid processed this period he did less well.
