desirable pawn structure wise but would leave the king unprotected.} (30...

the critical moment. This move g4 looked very strong to me, especially in
Sergey's time pressure since it seemed to me that if white's not just
obviously better, at the very least, it's much easier for me to play, and I
didn't want to give black easy choice in time pressure.} (31. Qh4 {Me and
Sergey analyzed this move after the game and it didn't seem totally convicing
to me. While I win the pawn, it didn't seem sufficient enough for me, as I was
overestimating my position quite a lot.} Nf5 32. Rxc6 {This was the point. But
even after I win the pawn it's not so easy.} Qb8 $1 33. Qh2 (33. Qf2 $6 Qb7 {

slightly better.}) (31. Nc5 {I turns out maybe I should've considered playing
by more positional means now that black's pawn structure is weakened.} Qb5 (

stopping black's counterplay with e5.}) 32. Qh4) 31... Nd5 $1 {The only move
but the best.} 32. Qf2 $6 {Right here I thought I had a really dangerous
attack but in fact black was already doing close to fine here. Me
overestimating my position almost cost me dearly this game. I was starting to
think a long time here, looking for a decisive continuation and couldn't find
one. As it turned out, there might be nothing here, even the positional way
might be too late now.} (32. Ned2 $5 {Would be a very mature move to play} Qb5

looking a bit at my king. I missed this move when I looked at qf2.} 33. Rf1 {

for black.}) (33. Neg5 Nxe3 {I was afraid of this move since I couldn't quite
figure it out but looks like white is better after all here.} (33... Re8 {

And already black is doing very well.}) 33... Nf6 $2 {The decisive mistake. I
was happy that I have foreseen this a move in advantage and my 34th move also.
However, I got very fortunate because Sergey was choosing between two moves,
33)re8! and this move and he had low time and he happened to choose the wrong
one. Sometimes in chess you get a little bit lucky.} (33... Re8 $1 {But after
this strong move, just one more solidifying move, Sergey's position would be
very sound and in fact all 3 results are possible here and already black has a
psychological advantage here since I'm still in the mode of overestimating my
piece and if I don't see anything very good I'd have a good chance of doing
something rash. As it turned out at this point I would've had to shift gears
and make sure I have at least equality. which would be hard to do. And he saw
this move, which is why I really feel lucky this game.} 34. Nc5 (34. Ned2 e5
