From the stem game: <25...Re6> 26.Qf3 Bh2+ 27.Kxh2 Qxf3 28.Bxf3 Nxd1 29.Bf4 Re7 30.Bxh6 Rh7 31.Bg5 Re8 32. Bf6 <Nxf2?> is weaker than:

<32...d3!> 33.exd3 Nxf2 34.Kg3 Nxd3

By playing <32.Kg3> as per my last post, Black avoids danger from the advance of the d pawn.

As <d3> seems a powerful motif in this position, I went back. So, why not:

By this time, I am begin to feel like that one time I tried to look inside a watch; while trying to put it all back together something would always spring out. This variation reminds me of that alot. A guy named Sysyfos comes to mind, too. Mnoga lieta: we will all need them. :-)

So, without much apology, I will spew a few variations:

I. After <31. Bg5 Re8 32.Bf6 d3 33.exd3 Nxf2?!> I was planning 34.Bd4 and if 34...Nxd3 35.Ra5, or 34...Nxh3 35.Kg3, or 34...Rxh3 35.Kg2, and things look well for White.

II. However, the much better 31. Bg5 Re8 32.Bf6 d3 33.exd3 <Rf8!?> forces a transition into an interesting endgame; 34.Bxd1 Rxf6 35.Kg3, and then perhaps this plausible continuation 35...Rhf7 36.Rc2 Kxb7 37.Bg4. I probably would prefer to play the White side of this instead of Black.

III. 33.exd3 <Rf7!?> looks similar to II.

IV. Now to your latest "nasty invention", 31. Bg5 <Re8>. Although your main line <32.Kg2 d3! 33.e3 [33.exd3 Nxf2! 34.Kxf2 Rxh3] Rxf3 34.Kxf3 Rf7+> and now 35.Bg4 may still be playable for White, its only barely playable. White would have a hell of a time untangling.

V. After 31. Bg5 <Re8> I was more thinking about something steming from 32. Rd5. For instance, 32...Nxf2?! 33.h4 Nd1 34.Rxd4 Nc3 and here I'v been mostly looking at 35.Rd8+ Rxd8 36.Bxd8 Nb5 37.Kg3 Nxa3?! 38.Kg4 Nb5 39.Kg5 and its not clear if Black can hold. Of course, the variation is long and only exploratory.

VI. Finaly, 31. Bg5 Re8 32. Rd5 <Nc6!?> and either 33.Rxd4 Nxe2 34.Rd8+ Rxd8 35.Bxd8 or

VII. 33.Rd8 Rxd8 34.Bxd8 lead both to quite interesting difficult endgames with chances for both sides.

<Ughaibu> 31...Rf8 <32.Bc6> Rxe2 33.Rd5 Rh8 34.Rd7 Rxf2+ 35.Kg3 Rc2 36.b5 Rc3+ 37.Kf4 Rf8+ 38.Ke4 Nf2+ looks better for Black

<25...Re6>26.Qf3 Bh2+ 27.Kxh2 Qxf3 28.Bxf3 Nxd1 29.Bf4 Re7 30.Bxh6 Rh7 31.Bg5:

Now <InspiredByMorphy> suggests:

31...Re8 32.Bf6 d3 33.exd3 Nxf2 34.Bd4 Rf8 35.Bg2 Nxh3 36.Bxh3 Rf3 37.Rb5 Rfxh3+ <38.Kg2> Rh2+ 39.Kg1 Rh1+ 40.Kg2 R7h2+ 41.Kf3 Rh3+ 42.Ke2 R3h2+ 43.Kf3 which is a draw.

In the above line, if <34...Nxd3> 35.Ra5 c5 36. bxc5 Rh4 37.Ra4 Nf4 38. Kg3 Rxh3+ is also a draw

<Gypsy> Your idea 31...Rf8 <32.Rd5!> Nxf2 33.h4 Ne4 also looks equal

By move 25 it seems that Black is surviving.White should be able to do better.So, looking further back, I suggest the following as a possible way forward for White:

<21.Bc1> fxg3 22.fxg3 <g5> 23.Rc5 Nd5 24.Qf5 c6 25.b5

I guess it is my turn to put up a couple of ideas.

First, I take the liberty to outline a finish to the "trap" line given above. The path to win there is still somewhat subtle. After the <21.Bc1 fxg3 22.fxg3 Nf5 23.Rf3 Ne3 24.Bxe3 dxe3 25.Rc6>, Black only reasonable defense is <25...Qd7>, but, on the surface of it, it seems adequate. Since White has to liquidate into an endgame: <26.Rxd6 Qxd6 27.Qxd6 cxd6> (only pawn should take), Black looks safe because of the bishops of different colors. The catch is that White b7 pawn is too strong and ties up the Black king and rook too much. White wins additional pawn(s) and marches down his own pawns on the K-side. A plausible continuation is <28.Kh2 h5 29.h4 Bd4 30.Rf4> and Black has to start droping pawns. After <30...Be5 31.Re4> or <30...Bb6 31.Rf6>, White will be up two pawns while his b7 pawn continues to tie up Black forces.

A review by Fritz 9 found an additional line that should lead to a draw for Black.

Fritz preferred the move 25...Bh2+, and then 26.Kxh2 Nxd1, and gave an evaluation of (.23) (19 ply), with a suggested continuation of 27.Bxh6 Nxf2 28.Qf4 Qxf4+ 29.Bxf4 Rd7 30.Bg5 Rh8 31.Kg3.

Fritz's evaluation was now (.07) (18 ply) with a suggested continuation of 31...Rf8 32.Bf3 Nd1 33.h4 Nc3 with an updated evaluation of (-.03) (17 ply).

I believe Black also draws after 31...Nd1 32.Bc6 Rh7 33.h4 Ne3 34.b5 Nf5+ 35.Kg4 Rh5 36.Re5 Nxh4.
