2008 State: Dimopoulos v. Strunk

My favorite game came in the third round when Prospect's Peter Dimopoulos upset Lincoln Way's Alex Strunk despite a rating differential of 500 points. Alex played the exotic Black Knight's Tango against Peters 1.d4. Despite never having encountered this opening before, Peter responded logically and aggressively. Alex let his development lag in the hopes of grabbing some pawns.

Both sides overlooked some tactical points that would have been very hard to find in a sixty minute time control without investing a good deal of one's clock, but Peter kept the pressure on and found the very pretty move 22.Nh8! to win the exchange.


A knight is usually at its absolute worst when stuck in the corner so trapping a rook by moving a knight into the corner warrants a lot of style points. Peter missed some opportunities to shorten Black's resistance after this but Alex had been forced to consume most of his time dealing with White's attack.

Two interesting points occurred in the ending where Peter made himself sweat more than he had to. In both cases, Fritz 11 thought that Peter's move was just as good as my proposed alternative, but since Fritz has no sweat glands, I still recommend my move. The first one occurred on his 48th move.


According to Fritz, Peter's 48.Ra5 is every bit as winning as my 48.Kc5, but the virtue of the latter move is that the rook keeps the Black king from ever getting near the White g-pawn. White simply advances the b-pawn until White is forced to give up the bishop.

One of the most important things a rook can do in the endgame is to confine the opposing king.

The next occurred ten moves later when Fritz liked Peter's 58.Ra2+ just as much as my 58.f7. After the latter move, Black queens first, but White queens with check and trades off the Black bishop and queen leaving him free to advance the b-pawn unhinderd. After Peter's move, Black has the opportunity to chase the White king around with checks for awhile.

Hello, this is Joe Man, Conant's 2nd board. I really enjoyed looking over this match between these two great 1st boards. I was surprised at all the different possibilities there were. I must admit that I would have missed them too when down on time. I also would like to pass my congratulations to the team for improving their rank from last year. Good luck in the future!
