Marqeta Talent Show: Simultaneous Chess

My office has arranged for a virtual fun event called Marqeta Talent Show where people can demonstrate their different talents in a festive manner. I thought of hosting a simultaneous chess show with some of my fellow players of Marqeta Chess Club. When someone joins Marqeta, they need to say what is their superpower, usually something funny or some passion that they cherish. When I joined Marqeta, I claimed my superpower as the ability to play chess in 10 boards in parallel with 10 opponents, making each move in less than 10 seconds and win all the 10 games! Of course, I am not that good, specially if 1 or 2 of the opponents are seasoned players then I have no chance. But then, a superpower is supposed to be flashy or funny. So I gave it a try. Our SVP Brian Keilly was hosting the All Hands and told me he wants to test my superpower. Well, it's not easy to arrange a simul like this and we decided we will figure out a way later. I remember every once in a while Brian would ask me - "Hey Ashik are you scared, you haven't given the test yet!" 😅So finally I thought this is the time when I can give it a try. 

5 of my colleagues were interested to participate in that talent show. Very nice of them, thank you! Last afternoon we ended up playing as a group and here are the highlights from that session. I was at risk of losing in the game against Charles but managed to win all the games.

Ashik and Ahyan's Round 5 and 6 Games in Mechanics Chess Institute TNM A...

Last Tuesday Ahyan and I played the 5th and 6th round of Tuesday Night Marathon online over chess.com arranged by Mechanics Chess Institute. The games are live analyzed by FIDE Master Paul Whitehead and Abel Talamantez. After a nice win by Ahyan at 5th round he was jointly in second position with 4 out of 5 in the open section which is phenomenal at his age and rating. Ahyan and I joined the commentary by invitation from TD Judit Sztaray after the 6th round for a short time. Here are some excerpts from our games and the commentaries. The TNM newsletter for this round may be found here - https://www.milibrary.org/chess-newsletters/931



Round 6:

Jonah Busch (Kondsaga) (1711) - Ahyan Zaman (ahyanzaman) (1496) [E11]

[de Firmian,Nick]

1.d4 Nf6 2.c4 e6 3.Nf3 Bb4+ 4.Nbd2 [4.Bd2] 4...d5 Old-style. [4...0-0 keeps options: 5.a3 Be7 6.e4 d5 (6...d6!? rather asks the N/d2, what are you doing there...7.e5 Nfd7 8.Bd3 c5 9.h4!? was a fun line until it was clarified that 9...g6! was the way to defend. (The "fun" happens after 9...cxd4?? 10.Bxh7+!) ; Or there's 4...b6 "committing" to the Queen's Indian.] 5.a3 [5.Qa4+] 5...Bxd2+?! This is probably White's "as good as it gets" against the Bogo-Indian. Two bishops, Black's unsolved bad LSB. [5...Be7 is almost always played.] 6.Nxd2!? [6.Bxd2 is 7 or 8 times as common -- but the text move scores better. And it makes sense, to contest e4 (guarding c4 is almost incidental).] 6...0-0 7.g3?!

MIOnlineAug.21_933

[7.e3 is more common by a lot, if more sensible, first played at least as early as 1931! 7...b6 8.cxd5 exd5 9.Bd3 Nbd7 10.b3 c5 11.Bb2 1-0 (29) Zamikhovsky,A-Rosenkrantz,K Moscow 1931] 7...dxc4!? Looks good, since White can't take back (... Qd5...). [But 7...Nc6! 8.e3 e5 highlights the problem. Black busts open the center and puts White on the spot. 9.Bg2 exd4 10.cxd5 dxe3 11.fxe3 Nxd5] 8.Bg2 Qxd4 9.0-0 Rd8 [9...Nc6! 10.Qc2 (10.Bxc6?! bxc6 when White will miss his king bishop even more than Black was.10...Na5 gets annoying.] 10.e3 [10.Qc2 wins back one pawn with sufficient compensation for the other (Black's queen gets kicked around more than she'd like).] 10...Qd3 Clear plus Black now. 11.Qa4 c3 [11...Bd7!? 12.Qxc4 Bc6 Who's your bad bishop now?] 12.bxc3 Qxc3?! [12...Bd7 here also] 13.Rb1 c6 [13...Nd5] 14.Ne4 [14.Bb2! Some queen-kicking coming.] 14...Nxe4 15.Bxe4 f5 [Not a lot of humans find 15...Re8! thinking about dulling the long diagonal with ...e5 at some point.] 16.Bb2 Qc5 17.Bc2 Rd2?! Black needed to be thinking development, defense. [17...Nd7 18.Rfd1 Re8] 18.Rfc1 [18.Bb3! thwarts.] 18...Rd7

MIOnlineAug.21_934

Black's position would be pathetic if he didn't have two pawns to show for it; but maybe that's not enough. 19.Bb3 Qe7 20.Qf4 threatens f5 [20.Qc4!] 20...Qf7 21.Qe5?! [21.e4! fxe4 22.Qxe4 Rd8 23.Re1 Is this a Bogo-Indian -- or a Danish Gambit!?] 21...Re7 22.Rd1 Nd7 Black might consolidate now! 23.Qc3 Nf8 24.Rd6 Rd7?! Black needs a plan. [How about 24...b6! intending ...Bb7 whether or not White takes on c6.] 25.Rbd1 Rxd6 26.Rxd6 Bd7 27.Qd4 Rd8?! 28.h4 [28.Qxa7! Qe7+/= 29.Qd4?! (29.Qc5; 29.Rd2) 29...c5!= 30.Qxc5? Ba4!] 28...Qe7 29.h5 c5 3:20 remaining

MIOnlineAug.21_935

The game has become critical. [29...h6!] 30.Qe5? 6:26 remaining [30.Qxc5! Ba4? (30...h6!= has to, has to be played!31.Rxd8! Qxc5 32.Bxe6+ Kh8 33.h6! and White mates.] 30...Re8?? Ahyan took a good minute on this move, but it missed the danger: that Alpha pawn is zeroing in on Black's king and must be stopped! [30...h6!-/+] 31.h6! winning! 31...Qf6 [31...Ng6 when 32.Rxe6!! (32.Qxc5 is about as good, and wins prosaically32...Nxe5 33.Rxe7+ Kf8 34.Rxg7!+- puts some flash into it.] 32.hxg7 Qxe5 33.gxf8Q+ Kxf8 34.Bxe5 With the extra bishop (and a powerful one at that on e5) White just wins the endgame. 34...Ke7 35.Rd2 Rc8 36.Bf6+ Ke8 37.f3 c4 38.Bc2 c3 39.Rd3 [39.Rh2] 39...Bb5 40.Rxc3 Rxc3 41.Bxc3 Kd7 42.e4 fxe4 43.Bxe4 Kd6 44.Bxb7 Kc5 45.Bb4+ Kc4 46.Kf2 Kd3 47.Be4+ Kc4 48.Bxh7 Kd5 49.Be4+ Ke5 50.Ke3 Bc4 51.f4+ Kf6 52.g4 Kg7 53.Kd4 Bb5 54.Ke5 Bd7 55.Bc5 Kf7 56.Bxa7 Kg7 57.Bd4 Kf7 58.Bc2 Bc8 59.a4 Bd7 60.a5 Bc8 61.Bd3 Bb7 62.a6 Ba8 63.a7 Bd5 64.Be4 Ba8 65.Bxa8 Kg6 66.Be4+ Kf7 67.a8Q Ke7 68.Qa7+ Kf8 69.Kxe6 Ke8 70.Qe7# Kondsaga won by checkmate 1-0

Became 2019 US National Class Champion In Under 2000 Section

I became undefeated champion today in 19th US National Class Chess Championship organized by BayAreaChess. I played in A section (Under 2000) in 2 days format while Ahyan played in B section . (Under 1800). I won first 4 rounds and drew the final round to be champion. Ahyan didn’t get a good tournament this time as he is trying to settle in this relatively new B section. So far all my games were hard earned slow endgame wins, three times being a pawn down with slight or no compensation. I should receive $1008 first prize along with the champions trophy. 


You may find the final standings here. Also I have recorded below all the 5 games I played in this tournament.






Rohan Rajaram (1794) vs. Ashik Uzzaman (1947) 1/2-1/2
Hyatt Regency, Burlingame, California: US National Class Championship: 2019.09.29

In the final round I needed a draw while my opponent Rajaram needed to defeat me to be champion. He thought he got me in the bag after his 42. Kd2. I am going to soon loose my c2 or g6 pawn with a good chance for him to win. But my reply 42... g5! threw him out. I virtually sealed the draw there by ruining his pawn structure despite going a pawn down. I remember Tournament Director Tom (who was watching the game) asked me later, where did that g5 come from? Moves like g5 is not intuitive and easy to miss, so I was very happy when I found it!
