  Marmot PFL: Good game by the challenger. Black made quite a few strange moves, starting with 23...Nxd2 which opens a big diagonal for the WB. Later 26...g5 makes that situation even worse.

  PhilFeeley: I know it's a Trompowsky, but after move 8, it looks an awful other like a London.

  ajile: A White Dutch Stonewall Attack without the bad DSB. What's not to like?

:o)

  ajile: Pro tip - Don't leave your king on a long diagonal that could be opened soon by attack. Bd3 and (..Kh7)

  AylerKupp: <<BOSTER> After 22...fxg4 game was equal.>

It's quite possible that this is a fairly equal position already, particularly if one considers a position to be equal if the evaluation is in the range of [ ±0.50]. According to Stockfish 9, after 22.Qg2, the top 20 possible responses by Black at d=33 had evaluations in the range [-0.27] to [+0.38] with the top Black move being 22...Qe8 (no, don't ask me to explain why). The move played, 22...cxd4, was considered 6th best by Stockfish with an evaluation of [0.00] (about as equal as they come) along with 8 other moves, and the 28...fxg4 that you suggested was considered 19th best with an evaluation of [+0.08], still pretty much the same for all practical purposes. So I don't think that Black's loss in this game can be attributed to 22...cxd4.

I personally would have played 22...c4 with the idea of following it up with ...b5 and ...b4 with pressure on the q-side to try to counter White's k-side pressure. But that's the French defense player in me. And if 23.Bxe4 then 23...fxe4 and Black will have temporary control of the f-file. The game's result might then depend on whether White's knight will be better than Black's (bad?) LSB in this type of position.

Not sure what you mean here but around then Black should have been able to hold the position.

  HeMateMe: textbook strategy, block the center and lock in a bishop, plan which kingside pawns to move that will pry open the opponent's kingside.
May-09-18  BOSTER: < AylerKupp>. I agree that 22...fxg4 is not the best move.I guess that most players don't like the pos where his king under pressure.
May-09-18  JPi: <with the top Black move being 22...Qe8 (no, don't ask me to explain why)> Maybe Qa4 then Ba6 <AylerKupp>
May-10-18  JSYantiss: 2 different mate possibilities at game's end. Nice game.
