Hi Razor, 24. Bxf4 is too strong, for instance:

23...b5
24.Bxf4 b4
25.Nb5 Nxb5
26.Qg3

I am working on an interesting idea relating to 23 ...b5.

If there is any hope I will let you know. I don't have an engine to analyse it so I'm looking through possible variations manually which may take more time.

The main points I am examining are that 24 axb6 frees the a8 rook with tempo, 24 Nxb5 allows exchange of knights and at the very least gives black some counterplay, Bxb5 could possibly be answered by something along the lines of hxg5 or Bxg6, the latter possibly going something along the lines of:

23... b5
24.Bxb5 Bxh6
25.Rxh6 Nxb5
26.Nxb5 Qf4!?

While other 24th moves by white such as Bxf8 could allow ...b4.
At the very least, ...b5 may give us some counterplay for material.

It's early days yet as I'm having to do this the old fashioned way, but I'm wondering whether an offbeat response such as ...b5 may give us more hope of catching Yulia off guard.

Hi all,
Actually ,I still find it hard to believe,how many voted for 2...g6.
2...e6 was the best move.

It is hard to believe how many people voted for xf4. The voters spanned the ratings so there must have been some attraction. It looks resignable but Zarkov can only see +100:

pv fxe4 Bxf4 Rxf4 Rg5 Raf8 Rg2 b6 axb6 axb6 Nb5 Qd7 +94 [Zarkov]

hi Bro. Rick:

Bro. Rick posted:

22...Bxf4
23.Rxh5 (23.e5 Nf7 -/+)

24.Bxf4 Rxf4
25.Rg5 Raf8
26.Rg2 b6
27.Bg4 b5
28.Ne2 Rf3
29.Qa1 Nf5 might be even!

-----------------

white might try:

27.Rd2 Qb8
28.axb6 axb6
29.Qb3 c4
30.Qb4 b5
31.Re2 Qb6
32.Nd1

If
32..Rf3
33.Bxf3 exf3
34.Rxe7 Nf5
35.Re4
(saving both R's and winning the exchange)

-------------

22..Bxf4 may be as good as any other move, but white has an extra piece for black's 2 extra pawns. However, black has broken up white's connected center pawns and has a thrust on the Q-side with the b and c-pawns.

If black plays best moves, this may be a difficult position for white to win. Having said that, I may have a winning continuation for white.

Hi JohnL, gmueller, & Team,
Thanks, seems I already had that analysis, I just hadn't promoted the variation.

Anyhow, I was just looking at 22...Bxf4. White must have a win but I couldn't find one!

Here's what I have so far:

22...Bxf4
23.Rxh5 (23.e5 Nf7 -/+)
23...fxe4 (if 23...Bxh6 24.Rxh6 fxe4 25.Rh3 Rf6 26.Re3 Raf8 27.Nxe4 Nxe4 28.Rxe4 Rxf2 29.Kd2 Rxh2 30.Kc1 Rff2 31.Qa4 Kg7 32.Qe8 Rxe2 33.Rxe2 Qf4+ [33...Rxe2 34.Rf1+-] 34.Red2 Qc4+ 35.Kb1 Qe4+ 36.Ka2 Rxd2 37.Rxd2 Qe1 38.Rd3 Qxa5+ 39.Ra3+-)

24.Bxf4 Rxf4
25.Rg5 Raf8
26.Rg2 b6
27.Bg4 b5
28.Ne2 Rf3
29.Qa1 Nf5 might be even!

Other White lines look even also. Could it be? I doubt it, but let's take a look. Seems our other moves don't look good for us.

hi Bro. Rick:

this is what I had for ..Bxe2:

dibbellebes posted:

If 21… f5 22.f4 then the immediate exchange of the light squared bishops could be helpful for us:

22… Bxe2 23.fxe5 Nxe4 24.Nxe2

[24.d6 exd6 25.exd6 Qd8 26.Nxe2 Nxg5 27.Bxf8 Qxf8 (27… Kxf8?) 28.Qxc5 (28.d7 Rd8 29.Qb3+ Kg7 slight edge for White) 28… Rd8 29.Qc7 slight edge for White]

24… Nxg5 25.Bxg5 Qxe5 26.Qxc5 f4 27.Qxe7 Rae8 28.Qxe5 Rxe5 29.Bh6 f3 30.Bxf8 Rxe2+ 31.Kf1 Kxf8 and now Black has a slight edge.


--------------

26.Qc3 Qd6 (Qc3 and Nf4 prevent ..f5
27.Nf4 b6
28.Rd3 bxa5 (the white R and B attack the e-pawn; also, a threat of mate with Q and B)

29.Re3 e5
30.dxe6 Qd4
31.Rd3 Qc3+
32.Rxc3 (white probably wins)

If
29.Re3 c4
30.Rxe7 Rf7
31.Rxf7

this is gmueller's ..Bxe2 line:

Hi JohnL & Team, I've been looking at your 22. f4 Nxe4 suggestion and most the lines look pretty good for White. Before I look at it in depth, please show me the main line that probably wins for White after 22...Bxe2 because everything I have shows a draw after 22. f4 Bxe2
Thanks, Bro. Rick

What's wrong with 22...Bxe2

hi Bro. Rick:

It looks like all possibilities for ..Bg7 and ..Bxe2 have been exhausted. How about 22.f4 Nxe4? black has Q+6P for Q+N+3P.

Hi JohnL, yes, very good, your 36....b5 draws. So my exclamation on 32.Qc4! should be 32.Qc4? since it only draws but 32. Qd5+! wins!

I found 32. Qd5+ coupled with Rg3.
