this a long time ago. I decided to stick to the familiar Hedgehog.}) 8. Bd3

into a deep think for more than 20 minutes. At least I made him work.} 21. e5

$1 {He said that White is still better here - and Stockfish agrees - but this
is much better than what happened in the game.}) 22. Bxe4 Bxe4 23. Nxe4 Qxe4

cxb5 Rc2 28. Qe1 Bc5 $1 29. Bxc5 Nxc5 {and somehow all the tactics have worked
out in my favor. But White shouldn't focus solely on the pin. Too late, I
realized that he can switch gears with 26.Rd4!, trapping the queen in the center of the board. And of
course 25...Qc6 26.Qd2 loses. At least the text move wins 2 pawns for the
piece.}) 26. Bxf4 Qxf4 27. Rxd7 Rxc4 {Give Black a chance to breathe, and ...
Rec8 followed by ...Rc2 could be trouble. But the GM efficiently kills off any
counterplay.} 28. Ng5 $1 {The knight is immune} Qxf2+ 29. Rxf2 f5 30. Nxh7 Rec8

He's pretty good at chess.
But let's back up a round. Dimitar Mardov is just 9 years old, but he already has a mighty 2100 rating. Future GM? When I was that age, I had recently discovered that capturing stuff was good while getting captured was bad. The prodigy and the former non-prodigy clashed in Round 2.

20. Qf2 Bc6 21. Be2 Ng7 22. Rf1 Qa8 23. Bd4 Qb8 24. Be3 {I had no intention of
taking a draw by repetition. As usual in the Hedgehog, White has burned up a
lot of time on the clock. On every move you have to check long variations with
...b5 and ...d5. By repeating the position, we get closer to the time control.}
b5 $2 {A lot of books on the Hedgehog tell you that Black should try to play ..
.b5. What they usually forget to tell you is that the pawn can become a
weakness if the advance is played prematurely.} 25. cxb5 axb5 26. Nb3 {

exchange sacrifice that begs to be played.} 55. Rcxc4 $1 dxc4+ 56. Kxc4 Rb8 ({
The sacrifice is so natural that hardly any calculation is necessary. The only
line I looked at was} 56... Rc7+ 57. Nc5+ $1) 57. b6 Raa8 58. Kb5 1-0
E4stat tied for 2nd place U2300, picking up 14 ratings points along the way. In a few weeks, we will be back to posting forecasts of top tournaments; the Candidates takes place in March.
