It was a tough game, as my opponent was making his moves almost instantly, within a few hours of my move.
The opening was a Caro Kann Panov, and followed the game Chatterjee-Dhanish, AICCF T-1508, till move 9.
After 16. Qxd5, we reach a critical position.
16...f5 seems to have been played earlier, as it is mentioned in an engine book, but I was not able to locate the game.
After 23.Nxb5, we reach a difficult endgame which is better for Black. But does he have a win, that was the big question.
Perhaps 25...Rf1 would have put up a more spirited defence.
it is the story of the king in the dungeon. He can only shuttle between h1 and h2. Now, the White isolated pawns will fall.
The rest should have been simple, but my opponent kept on playing till we reached a tablebased King and Pawn ending.
SM Klausen, Tor-Arne continues to lead the tournament with 9 points.

Re: Israeli Championship 49
Glad to know that Mr. Dhanish has a 'good' score i.e. draws with leaders and 2 wins vs others and expect him to win this tournament. When this ty. is over one may expect that his best games are annotated in AICCF Bulletin. Wish him all the best!

I thought I had an advantage in the early middle game, but could not make it work. There were lot of alternatives around moves 21 to 23, but the complexities were too much, and some of the lines appeared to be too risky.
Finally, the position got simplified too much, and when my opponent offered a draw, I accepted.
14 ... Qxe5 15. Bf4 Qf5 16. Bb5 O-O 17. Bxc6 Nc5 18. Bxe4 Qxe4 19. Qxe4 Nxe4 20. Rad1 Rfd8 was Kokol,P - Margvelashvili,G, Kemer, 2007 drawn on move 50. I chose to deviate with 14 ... Qd5. But now, I find some engine books recommending the move, so perhaps it's played before.
Perhaps 21. Be3 h5 22. Nxd3 exd3 23. Rxd3 Rxd3 24. Bxd3 f5 was better. Now, the bishop gets trapped. Of course, engines fail to realise this. Position after 23...b6:
24. Rad1 Kb7 25. Bxb6 Kxb6 26. Rxd8 Rxd8 27. Rxd8 Bxd8 28. Qxh7 appears to give more resistance.
After exchange of queens, Black will attack the White pawns with rook, king and bishop, when they have to fall.
My fifth win in the tournament came when Vaitzel, David Grigoryevich, 75 year old player from Israel resigned his game as White, see http://www.iccf-webchess.com/MakeAMove.aspx?id=258230. This game gave me great satisfaction, as I was able to convert a slightly better double rook endgame into a win, without any obvious blunder by my opponent.
The opening was a Caro Kann classical. 10...Ngf6 is recommended by most books, but database statistics showed better results for Black with 10...Qa5.
13...Rd8 may be a new move, I am not sure.
After 29.Be5 Bxe5 30.Rxe5, only the major pieces remain. White thinks that "all rook endings are drawn" and is simply shuffling pieces without any active plan, clearly aiming for a draw.
When the Queens are exchanged on move 41, engines show only a slight advantage for Black. But I think it is a win for Black due to a) the weak pawn on g3 b) possession of the h-file, c) active rooks and king. Slowly, Black will push forward his kingside pawns and win the g3 pawn with a multiple attack on it.
With 56...Kg5! , White appears to win two pawns, but the Black pawns become unstoppable.
After 61...f4, White could have as well resigned, but he elected to play on.
Up to move 70, White usually used to reply within a few hours. But after that, he started to take several days.
On 75...Qxd4, a tablebase position won for Black is reached.
Finally, Black resigned on 2 Mar 2011, possibly after the cut-off date for the next rating list valid from April 2011.
Now, I am in the second position in the crosstable:
15...Rf8 16.Kh2 f5 17.f4 b5 18.axb5 axb5 19.Naxb5 fxe4 20.Bxe4 Bd7 21.Qe2 Qb6 22.Na3 Rbe8 23.Bd2? was the famous game Korchnoi-Kasparov, Luzerne (Ol) 1982 where instead 23.Qd1! wins for White. I remember going through the game in the very first issue of Chessmate. The knight remaining en prise for several moves created a great impression in my mind and I very much wanted to play the same line, but decided to be discreet after going through various published analyses.
21.Bg5 h6 22.Nc4 Qb4 23.Nxe5 Bxe5 was Avrukh-Bar, Israeli League 2008.
According to Avrukh, after 23...h6 24.Bh4 g5 25.Bg3 Bxf6 26.Ne3 White keeps control and has a slight edge. But I varied with 23...b5!. This activates Black's pawn majority, not bothering about the Bishop incarcerated at h8. In my opinion, Black is clearly better.
With 26.Ra7 White occupies the seventh rank, but his other pieces are languishing behind, and cannot make any use of it. But when the Black rook occupies his seventh with 31...Ra2 they are well supported by the queen, bishop and knight and they jointly demolish the White camp.
Instead of 34. Nc2? 34.Kh2 and instead of 35.Rf2, 35.Re3 appears to be better. Now all the Black pieces are cooperating harmoniously and soon the Black pawns will push through.
White resigned on the 41st move, after thinking for 25 days. The position was full of tension and hence the resignation was a surprise, but anyway the position was lost for White. Play could proceed 41.Bxg5 hxg5 42. Qxg5 Ng6 43.Nde2 cxb3!
2.e4 I am not normally a 1.e4 player, but it was not much earlier that I had lost three games in the ICCF interzonal playing the Black side of the French defence, so when my opponent offered the opportunity, I could not resist transposition!
14.f4 N ChessOK opening tree gives 14. Qh5 1-0, Berg Emanuel (SWE) - Berelovich Aleksandar (UKR), Fuegen (Austria), 2006
14...Qg7 14...Qh8 appears to be better.
20...e5 ? Black gets fed up with passive defence and tries to open up the position. 20...d4 was necessary.
45...Ne5 45...Nef6 looks better, but of course, may not make much of a difference to the result.
After 50...Rh6, Black exceeded the time limit, and I made a claim which was accepted by the Tournament Director.
Congratulations to Shri P.B.Dhanish on attaining the title of Senior International Master (ICCF-SIM). This title has been acheived by only one AICCF player previously - N.R.Anil Kumar. Santhosh Matthew Paul also came close.
What a fantastic victory. I thoughroughly enjoyed the endgame especially the position at white's 66th move where evaluation was critical. The game ended after 99 moves!
I congratulate you on being at the top of the Cross Table with 11.5 points. The only game you have remaining is against Fabio Piccoli of Brazil.
