Round 1

Ikeda 1-0 Akash 2069
Priyadharshan 2376 1-0 Zulfic
Ly 1-0 Chaithanyaa 2088

Guo draw Kulkarni 2317
Heredia 2076 1-0 Narenthran

Emma's game was a comfortable draw in 28.

Moulthun and Junta both get mid-2500 GMs in round 2. Very strong field. Top seed on rating GM Matlakov drew to an FM in the first round.

Games start 6pm our time I think. Live http://www.wjcc2011.org/LiveGames.aspx

An upset with second seed GM Sanan Sjugirov (who beat Carlsen in last year's Olympiad) losing to an FM, Nicolai Getz. Getz gave up his queen for three pieces and his three pieces were too strong.

Emma and Junta have both been defeated. Fedja drew against an opponent rated 2288, Moulthun's live game against a GM looked drawish when the transmission froze [edit: resumed and Moulthun is a pawn down] and Savithri lost a long game against an opponent rated 350+ points higher.

Not quite that class. The original giving up of the queen is good and white is always better but the game is later marred by a pawn blunder by black and a missed quick win by white before the right result eventuates.

What is Moulthun's status re an IM title? If he has the norms and just needs to get to 2400 then he may be there.

Going by the FIDE site he was sitting on a 'live' FIDE Elo of 2399 before this event and would have gained a few poinst in the first two rounds of this event, so the question is whether or not he's lost points in other recent events (and if he does actually have the norms or not).

He crossed 2400 after his second-last game so the fact that he finished on 2399 (live) is irrelevant, since crossing at any point of any event is sufficient even if you later fall below. He has already qualified. And yes he has the three norms.

Kevin Bonham

Unfortunately the live board is showing that Moulthun lost to Martinovic. It is also showing only eight moves but there are some other boards also showing very small numbers of moves and decisive results so very likely the game was longer than that.

Shreyans (2203) gets shredded by Fedja, making a few suspect moves then blundering a piece in a pretty much losing position.

Ikeda won in 52 moves. Emma won in 40 playing an Exchange French against her lower rated opponent. Contrary to the exchange variation's reputation for drawishness, it is only really so if both players want it that way, and can be very sharp at least below GM level otherwise.

Emma should have lost but her opponent blundered into queen sac for mate next move in a completely won position. Perhaps they were both in time trouble.

Moulthun won easily, while Emma, Savithri and Junta all lost although Junta briefly seemed to have drawing chances after giving up the exchange and swapping queens.

Fedja missed a very large number of winning lines (7-8 by my count) but still a draw against a player rated 200 points higher is no disaster.

Savithri has won because she remembered her theory (all 19 moves of it) while white didn't know it. 9.Kf2 is bad and this is why. The entire game including the temporary queen sacrifice up to 20.g4?? (which gets mated) is analysis by Paul Keres from the mid-50s that remains unrefuted.

It's been very scrappy and stop-start throughout but this is no surprise given the number of boards they are trying to run at once. Can't actually remember an attempt to cover every board in this event before.

Junta has won. Slightly lower-rated opponent put up a good fight and should have drawn but went astray around the dreaded move 40.

Not much better today with Moulthun, Junta and Fedja all losing to Gahan (2188), Shreyans (2203) and Lokesh (2194) respectively. I wonder if local conditions are taking a toll on our forces. However Emma defeated Roberta Brunello (2036) and Savithri drew with Lluvia Angelica Mejia Salinas (1886) so it wasn't all bad.

Emma again had the good fortune of an opponent with a completely won position picking the Disaster Move instead.

Moulthun unfortunately lost to Pradeep (2245); it was an uneven position with chances for both sides until a tactical error resulted in Pradeep winning a piece.

Fedja smashed Arun (2018) on the black side of a 3.Nf3 Scandinavian (by transposition.) Interesting to see this since in the last few days Max Illingworth played the white side of a 3.Nf3 Scandinavian but drew against a higher rated player. I will post Fedja's game soon.

Savithri is in an even double rook endgame against P. Bala kannamma (1931) [edit: drawn, another good result for her] and Junta's position aginst Niranjan Navalgund (2188) looks bad but messy.

Early leader Rombaldoni had a loss today. The new leaders on 7 are GM Hovhannisyan and FM Girish. Girish has defeated four GMs in a row.

Fedja's game. Basically it was a sharp position and the opponent's play was nowhere near sharp enough, while Fedja's was much more direct.

Re Emma's draw. There seem to be quite a few Schliemann Ruy Lopez's played these days. 4 d3 is a good line for White. Anton Smirnov plays the Schliemann a lot. I used to play it in my younger days but not with any great success!

Following heroic resistance in a repeatedly nightmarish position Junta has managed to draw his game in 153 moves.

Junta was able to scramble to a position with rook vs rook and bishop which was drawn. The DGT board moves for the endgame were incorrect (see below).

Having played through the finish of Junta's game I have to wonder if the ending is real. Surely one would think a player rated 2188, even if down to the increment and on the verge of collapsing from exhaustion, would still convert some of the incredibly obvious endgame wins on offer here. Maybe the draw was obtained earlier and an under-8 took over for endgame practice - but the moves were coming through at a normal game speed!

[EDIT: See post a few down; the ending as per the DGT board is as I suspected incorrect, the c-pawn was off the board and it was just KRB v KR.]

Anyway I counted eight missed wins before the tablebase endgame was reached.

Navalgund - Ikeda according to the DGT viewer. It's actually quite interesting.

Many thanks Kevin for keying so many moves in manually! :clap:

It turns out that although the game was that long the last 40-odd moves from the game viewer are incorrect (as I suspected) and the c-pawn was off the board so it was just KRB v KR without the pawn - thanks to Ian Rogers for letting me know this. It is still an example of never, never, never, give up though!

Ian also notes that in Guo-Madhurima (post 11) both players were in severe time trouble (under a minute left) when Emma spotted the queen sac swindle and the opponent fell into it missing a win that would not have been calculable in the available time.

Moulthun is back on the winner's list - opponent tried to be too aggressive and blundered a piece to a queen fork threatening mate.

Emma had a solid draw against her slightly higher rated opponent. Rest still going.

Junta won, Fedja lost a long queen ending and Savithri had a wild king-hunt against her higher rated opponent which didn't quite come off and eventually liquidated to a win for the opponent (good try though). The games haven't been showing up on playchess much lately.

Too busy with admin work and going out tonight to watch games but:

Junta (4.5 before this round) defeated Mithil Ajgaonkar (2130) and now (5.5) plays GM Jorge Cori (2514)
Moulthun (4) defeated Soares (2181) and now (5) plays FM Gagare (2223)
Fedja (3) lost to Prasanna (2032) and now (3) plays Rodriguez (1997)
Emma (3.5) lost to Mahalakshmi (1901) and now (3.5) plays Hansen (1770)
Savithri (3) lost to Anjana (1830) and now (3) plays against Brunello (2036)

Swiercz beat Girish to go to half a point off the lead and plays the leader Hovhannisyan on top board next round. Ter-Sahakyan is also half a point off the pace. In the Girls event WGMs Cori and Girya have cleared out to 8.5, 1.5 points ahead of anyone else.

May have been a few moves played at the end - not clear.

Very interesting game starting with an early g-pawn attack that became a long-term sacrifice. Junta bailed into the pure pawn ending that became the queen ending probably because the rook ending was looking sticky otherwise. The final position above is a tablebase win for black but if the draw was agreed slightly later it may have ceased to be.

Emma won (quite convincingly I think), Moulthun unfortunately had another loss (not having a good tournament), Fedja's game crashed in the viewers after 13 moves at which point he was better, Savithri missed some fairly difficult combos for likely wins and is in very drawn looking OCB ending at the moment.

I am sure that white was completely winning before, but quite unwittingly went into KRB vs. KR which is a draw by best play. Ikeda was very lucky even in that phase in escaping 3 forced wins in the continuation - of course much easier for me to check with tablebases but still a good scare. Firstly why didn't black play 135...Rxe4= it just draws on the spot? Maybe the PGN score is wrong still? Maybe he overlooked 136.Rh8+,Re8 and there is no win for white?

After 136...Kf8?? 137.Rf7+! it was +-. The moves 139.Rb4! or 139.Ra4! forces 139...Rxd5+ or 139...Kf8 140.Rg4,Rxd5+ winning.
After 142.Re2+! Kd8 143.Rh2 or 142...Kf8 143.Rg2+- it would also be over. After 142.Rh2??, Rf4!= it was again a draw, but 148...Re1+?? +- was another losing move, but for 149.Kd6??= (149.Kf6!+-). The final move 153...Rg4! with the stalemate point was cute, but in fact only move, and the position was a draw from 149.Kd6 till the end in move 153. I guess they were pretty tired in the end? So how many wins did white in fact miss? Kevin how is the score?

Assuming the PGN of the ending is correct then it is something like twelve. I mentioned 108.Rh1 which also works on 109. in the corrected score. On move 110. Ra1+ is a clear win. Whether or not 111.Bf1 wins (and in how many hundred moves if so) will have to wait for the seven-piece tablebases.

Still no disgrace especially given the pressure and the relentless time trouble under increments. I missed about that many wins in a dreadful 40-50 move game against a c.1200 strength player once. Admittedly I had an excuse since I was also an arbiter in that tournament and there was an incident in that round with a rather excitable player who was attempting to refuse to score.

Thanks for checking out the KRB. I meant to do that but did not get around to it.
