2020 Pacific Coast Open: Better Late Than Never!

Before the COVID-19 pandemic occurred, the Pacific Coast Open was scheduled to be held last July in California. Unfortunately, the current situation precludes that, and the Continental Chess Association (CCA) made the decision to move most of their canceled over-the-board events online. The dates for many of those events have been different, as well as formats (time control, rounds, prize fund), but at least these events were held to continue the tournament’s tradition. In order to keep the regional flavor, entry fees were significantly discounted for those who live in the region where the OTB event would have been held. 

With that backdrop, the 2020 Pacific Coast Open was held September 26-27 and hosted on the Internet Chess Club (ICC). The event did not quite match the size of its OTB tradition, though it did have an $8,000 prize fund and drew 165 players across four sections. The top section had 29 players and drew 5 grandmasters, as well as an international master and women’s fide master. 

Upsets started occurring as early as round one, and titled players were not exempt: IM John Watson lost to Derek Chen, FM Matthew Casella lost to Thomas Li, and GM Michael Rohde surrendered a draw to Iris Zhou. Not surprisingly, the names of these players would come up again in the prize calculations! 

Round two brought even more surprises. Top-seeded GM Gusir Guseinov, playing from Azerbaijan, faced rounds at hours in the middle of the night. He attempted a nap after his first game, but unfortunately did not wake up in time for round two, forfeiting to Derek Chen.  

An even more-surprising result occurred when Donald Johnson defeated Rohde in this second-round game. On move 10, Johnson made a thematic piece sacrifice which correctly needed to be accepted. Rohde’s decision to decline the sacrifice, however, left him quickly in a losing position.

The lack of development and king safety are just too much.} e5 12. f4 Be7 {Moves such as Nfd7 or Nbd7 might be a little better, but white's attack is very strong.} 13. Nf5 O-O {Seems to make sense, but moves like e4 or Nfd7 (responding to the threat of fxe5 dxe5 d6) or Nbd7 are better, but then white's attack just continues with Nxg7+.} 14. fxe5 {14. ... dxe5 15. d6 Bxd6 16.

Bg2 {Now he plays Bg2, but d7 would have been much stronger.} Nd3 35. Rd1 {Good enough, but white doesn't even need to move the rook. 35. Bxe4 followed by d7 is best.} Ndxc5 36. Bxe4 Nxe4 37.

Only four perfect scores remained after two rounds: GMs Aleksej Aleksandrov, Timur Gareyev, and Jakhongir Vakhidov; as well as Chen.  Aleksandrov, playing through the night from Belarus, opted for a third-round bye, which brought Gareyev and Vakhidov to be paired on board one. Vakhidov had a nice combination to defeat Gareyev after 17. g4 -- can you spot the tactic?

Board two also featured this exciting game between Chen and Johnson. The players castled on opposite sides, and a tactical melee ensued.

The position starts as relatively equal.} 24. c4 { White makes the first significant error. Opening the position should prove fatal. White could have continued the attack with Bf5 or Be6 or played Kb1 or Kb2.} Rea8 {This move is not bad, but after 24. ... bxc4 25. bxc4 Qc5, the lines to the white king are open and black's attack is much faster than white's attack and will prove decisive. Also promising, but not quite as strong is 24. ... a4.} 25. Qg5 {Black is not winning, but is better with the same plan of 25. ... bxc4 26. bxc4 Qc5. Instead of 25.

Rxg8 Nxg8 28. f4 and the position is still equal even though it is very unbalanced.} a4 {This move allows white to keep some of the lines closed. It may look like white has the tactic of 26.

Bf5 is also good and still leads to an unbalanced equal position for both sides.} Ne8 {Now black is lost again. Black had to find a really strange move of 27. ... h6. The point is white has to play 28. Qd2 to prevent the black queen from coming in with 28. ... Qe3+ if the white queen leaves e3 undefended. } 28. Kb1 {White is still winning and this move gets the king off of the dark squares so that Qe3+ will not be possible, but Rg4 or Rg3 would have been correct. If white is going to move the kinng, he should play Kc2 so that countertactics involving Qxg1+ will not be possible as well as the white king does not want to be on the b file. .} Nc7 {This is the best move but might be hard to see. White is still winning, but the move is very hard to see,} 29. Bf7 {Now black is back in the game and the position is unbalanced and equal again. The winning plan was 29. Bg8! and black cannot defend after 29. ... Kxg8 Qf6!. Black cannot ignore the bishop because of threats like Bxh7 and white is getting to the king.} Nb5 {Now black has threats and counterplay with moves like Na3+ or Nc3+ depending ow white's plans.} 30. Qh6 {Black needs to force a repetition and white needs to acquiesce. Either Na3 or Nc3 forces Kb2 Nb5 Kb1 and the position repeats. White doesn't have time for other moves. For instance: 29. ... Na3+ 30. Ka1 Nc2+ 31. Rxc2 Qxg2 (31. Kb1 Nxb4) 29. ... Na3+ 30. Kb2 Nb5 Black as to go back to b1 because of threats of a3+ c3+ or g6.29. . ... Nc3+ 30. Ka1 Ne2 31.

After the carnage of the first day, three of the five GMs had withdrawn! Only two perfect scores remained at the halfway point: Vakhodov and Chen, who had entered as the 24th seed. On Sunday morning the two faced off, with Vakhidov emerging victorious and the only player at 4-0. He was closely followed by Aleksandrov who stood at 3.5/4, and Li and Chen at 3/4. These four players were matched in the penultimate fifth round: Vakhidov and Aleksandrov were content playing to a six-move draw, while Li suffered a tactical oversight and dropped his game with Chen. 

Going into the last round, Vakhidov maintained clear first with 4.5/5. Only Aleksandrov and Chen were within range at 4/5 each, though Vakhidov had already played them both, and he was paired down a full point to Ethan Sheehan in the final round. Vakhidov’s win there secured him in clear first place, finishing with 5.5/6 and winning $1,200. 

Aleksandrov defeated Chen in this game to finish clear second with 5/6. Aleksandrov won $600.

Rgf4 {The position is approximately equal and this move seems pretty easy to find. At this point, I wondered how either side would win.} Kh8 {Kh8 and Kg8 lead to approximately the same evaluation. There are plenty of other moves that stll maintain the balance such as Qc3 or Re7 among others.} 37. f6 {According to Fritz, this is best but there are still several moves that maintain equality including Kg2 or gxh6.} gxf6 {Again, many moves are possible including Rf7 or g6 all of which are still keeping the balance.} 38.

Black opts for the only other move that allows for playing for a win, even thiugh the position is still equal,} 39. Qxh6+ {Whitw had a number of moves at his disposal. He could have even played 39. ... Rxf5 or Re1 due to the tactics of the queen checks,} Kg8 40. Qg6+ {White had a number of moves in the position. One way to force a draw would be 40. Rxf5 when black may need to force the repetition with 40. ... Qg3+} Qg7 {The only move to avoid the repetition.} 41. Qxg7+ {41. Qh5 also maintains equality.} Kxg7 42. h5 Re5 43. Kg2 Ra8 {Both sides have been making "best" moves and the position is still equal.} 44. Rxf5 {Unfortunately white now blunders. White needed to play either Rh4 or Re1.} e2 {White could resign, but throws in a check first.} 45. Rf7+ Kg8 {White resigns} 0-1 [/pgn]
