Dallas vs Arizona

  1. GM Julio Sadorra (DAL) vs GM Rogelio Barcenilla (ARZ) 1F-0F
  2. IM Mackenzie Molner (ARZ) vs GM Conrad Holt (DAL) 1/2-1/2
  3. NM Artur Safin (DAL) vs FM Pedram Atoufi (ARZ) 1-0
  4. NM Dipro Chakraborty (ARZ) vs Travis Guenther (DAL) 1-0

 

Curiously enough we won this match 2.5 to 1.5, but then the board one result was reversed.  It turned out Rogelio had been using Houdini before the game to prep, then closed the laptop lid and brought the laptop to the match and started playing.  Running Houdini during a game is a big no-no and ICC auto-detects this.  Of course, all the players were seated at a single table under the supervision of a site TD and nobody was looking at computer analysis during the game, but the background Houdini process was the first nail in the coffin.  The second nail was the fact Rogelio task-switched away from the ICC game during the game.  He was in a chat with a family member, but this task-switching coupled with the background Houdini process was enough for the remote TD, Chris Bird, to pull the emergency brake and rule a forfeit.  Arizona appealed and it was thrown open to the other league managers for an appeal vote, but to no avail.   The one-two circumstantial evidence punch was just too much.  This was too bad because Rogelio actually played creatively setting up various nice mating motifs after his opponent admittedly took things too far in the risk department.

White’s king is a goner!

Exciting stuff.  Molner had a league reverse in a Winawer vs Tatev Abrahamian in a prior season and hopes to do better.

Forced and adequate.

Somehow the game feels very logical!  Black plays where he is strongest and white is forced to go for a perpetual!

This was a nice game and one of the GOTW contenders.

Black is equal here.  After 41…Rd1+ white has no winning chances.  For example,  41… Rd1+ 42. Ke2 Rb1 is equal as is 42… Ra1.  If 42. Re1, Qa6+ 43. Kf2 Qa7+ is equal.

42.Qb3 Kh7 43.Re1 Qg3?

Black’s king is so safe he’s fine here.  43… Rb4! 44. Qxd5? Rb2! 45. Qc5 Qg3 wins for black!  So, after 43…Rb4!, white must play something like 44. Qd3 Rd4 and has only tiny winning chances after 45. Qe2 Ra4 46. a6 Qf6 followed by d5-d4.

44.Rd1 Rc4 45.Rxd5 Qc7 46.Rd1 Rc2 47.Kg1 Re2 48.Qd3 Ra2 49.a6 Qg3 50.Qf1 Qc7 51.Kh1 Qb6 52.Ra1 Rxa1 53.Qxa1 Qa7 54.Qa4 g5 55.Qe4+ Kh6 56.Qc6+ Kh5 57.Qa4 Qe3 58.Qa1 Qa7 59.Kh2 Kh6 60.Qa2 Qc7+ 61.g3 Qa7 62.Kg2 Kg6 63.Qe6+ Kh7 64.h4 gxh4 65.gxh4 g6 66.Qa2 Kg7 67.Qb2+ Kh6 68.Qh8+ Black resigns 1-0

A thoroughly unnecessary loss by our third board.  This missed half point became very important after our first board’s result was reversed.
