Here is my annotated RHP game in Grob.
Dragon_fire - Korch
1.g4?!
I would not call this move decisive mistake, but its definetly at least dubious - it weakens kingside too much. If black knows how to play, then its white who will have to fight for equality.
1...e5
In my opinion this is the best response for black (instead of 1...d5 which seems to be more popular) for some reasons:
1) It does not create targets for white (after 1...d5 white will attack this pawn with Bg2 , c4 and possibly Qb3)
2) It makes possible counter attack in kingside which in my opinion is the best plan for black against 1.g4
2.c4?!
I really dislike this move for white - if they have weaken their kingside then they must develop their pieces to be able defend their weaknesses.
Much better is 2.Bg2, but anyway 2....h5 gives for black better play. for example against 3.d4 (hoping after 3....dxe4 4.g5 to get some compensation for their pawn) I would recommend 3...hxg4! 4.dxe5 Nc6 with better position for black.
2...h5 3.gxh5 Rxh5
3...Nf6 was not bad too, but black will have to take this pawn anyway, and with rook (Because knight on h5 is not so useful as rook). this game shows that such active rook can be useful even in such early stage of the game.
4.Nc3 Nf6 5.Bg2 Bc5
Plan, about which I have written in comments for black first move - black pieces are aiming for whites kingside which is weakened.
6.e3
Covering f2 from black bishop and giving e2 for white knight - also making impossible 6...Ng4
6...d6
This position I would rate as better for black - due to such strategic factors as open h-file for black and weak h pawn for white. Engines usually underrate importance of such fineses - Rybka rates this position as about equal (about -0,20).
7.d4
According to Rybka this move is slightly better than others, but I`m not sure about it. 7.Nge2 and 7.Nf3 was possible, but I like 7.Ne4!? Nbd7 8.b4! (getting space in queenside) Bb6 (not 8...Bxb4?? - 9.Nxf6+ Nxf6 [otherwise white queen will take black rook] 10.Qa4+ +-) 9.Ng3 which seems playable for white. Other interesting line is 7.a3 Rg5!? 8.Bf3 Nc6 9.h4 (9.Nge2 Bh3!) Rg6 10.h5 Rh6 with better position for black.
7...Bb6
7...exd4 is playable but i disliked position after 8.exd4 Bb6 9.Nd5. In this position white could play 8.dxe5 dxe5 9.Qxd8+Kxd8 10.Nge2 Nc6 and this endgame is much better for black, because white cant exploit black uncastled king, but their weaknesses are becoming more important in middle game without queens. 8.Ne4 is worth of consideration, but anyway - after 8...Rh6 black is better. But these moves was not so bad as move in game.
8.Bf3? Rh4!
Making rook active with pressure on d4 (in some lines moving pawn to e4 is good too). So white have nothing better then move into endgame in worst redaction, than it was possible in 8th move.
9.dxe5 dxe5 10.Qxd8 Kxd8 11.e4
Covering pawn on c4 and getting more space for black squared bishop, but making white bishop more passive.
11...Be6 12.Bg5 Rh8 13.Rd1+ Nbd7
At first sight white seems to have better - they have activated some of their pieces finally and black king is in center, but........black is still better because of these factors:
1)White cant exploit position of black king;
2)Whites knight on g1 is still useless and bishop on f3 is rather passive, while black bishops and knights are well placed;
3)Black still have opened h-file and better pawn structure;
But As I understood my opponent ( and not only he) rated whites position as better. So he dont feel any danger.
14.Nd5 Ba5+
Black does not want to exchange their strong bishop.
15.Kf1
If 15.b4? then 15...Bxd5 winning pawn.
After 15.Bd2 black could play 15...Bxd2+ with Rh4 and in strategic point of view this endgame is winning for black.
15...Ke8 16.b3
White will have to do this move anyway - after c6 they will have to think how to protect pawn on c4.
16…c6
Forcing exchanges
17.Bxf6?
White needed to keep their black squared bishop and exchange it only for black bishop. After 17.Nxf6+ gxf6 18.Be3 f5 19.Ne2 fxe4 20.Bxe4 f5 white have unpleasant but still defendable position.
17….Nxf6 18.Nxf6+
After 18.Ne3 Rh4! 19.Ng2 Rh6 20.Ne3 Ke7 21.Ne2 Rh8 black have decisive initiative. For example 22.Ng3 g6 (not letting knights on f5) 23.Kg1 (23.Kg2 Bh3+ 24.Kg1 Bb4 is not better) Bb4 with Bc5 and white are helpless.
18…Nxf6
18…gxf6 19.Ne3 Nc5 20.h4 Ke7 also would give black large advantage, but 18…Nxf6 seems to be better.
19.h4
Right decision. On h5 weak h-pawn will stand better and can become dangerous if black will be too careless.
19…Ke7 20.h5 f5 21.Ne2
Rybka advices 21.h6 first, but after 21…fxe4 22.Bxe4 f5 23.Bc2 Rad8 24.Rxd8 Bxd8 white will lose h-pawn and the game. But engine did not understand it for a some time.
21….. fxe4 22.Bxe4 f5 23.Bc2
Black attack in center made white to move their bishop on other squares, where he wont be able to protect h pawn , but together with knight he will make pressure on f5.
23…Rh6
Black plays very safe. Now white pawn on h6 is blocked. I think Nimzovitsch would like this move.
24.Ng3 Kf6 25.f3
Don’t letting black pawn on e4, but weakening knights position on g3. but what else white could do?
25…Rg8 26.Rg1 Bb6?!
From this moment black started to play quickly and careless, thinking that they can win whatever they want.
Playing 26...Bc7! black could win. For example 27.Rd2 (with idea of Rg2) e4 28.Rdg2 Rxg3 29.Rxg3 Bxg3 30.Rxg3 exf3 and this endgame with extra pawn black should win. But anyway - after text move black still have winning position.
27.Rg2 Bc5
Don’t letting white rook to d6
28.Ke2 Rh7?!
Why not 28…e4 with idea Ke5? White could have 2 main choices but in both of them black could got winning position:
1) 29.Rh1 Ke5 30.Rhh2 Bf7 (with threat of tasking on h5) 31.fxe4 f4! 32.Ng1 Rxg2+ 33.Rxg2 Bxh5+
2) 29.Rf1 Ke5 30.f4+ Kf6 31.Bxe4 Rxg3 32.Rxg3 fxe4
The text move had idea of doubling rooks on g-file but…..
29.Rh1!
…and 29….Rhg7 would lost after 30.h6!
29….Rg5
Don’t letting white knight to move.
30.a4
White have no active plan so they have nothing better than standing where they are and making harmless moves, awaiting what black will do. But black, having problems of finding winning plan, doing the same too.
30…Kf7
The best plan for black was Bf8-h6, doubling rooks on g7- g8 and after then moving with bishop on f4 which forced exchanges of both rooks and knight, after which black would take pawn on h5 with winning endgame. In next moves both sides are doing nothing awaiting for other to start some activity.
31.Rhh2 a5 32.Kf1 Bb4 33.Bd3 Rh8 34.Bb1 Bf8
Black have found first part from the right plan. But second part of their plan – doubling rooks on d-file wasn’t the best
35.Bd3 Bh6 36.Bb1 Rd8 37.Bc2 Kf6 38.Ke1 Rg7 39.Kf1 Rdg7
Good trap, but bad plan in case if white would simply play 40.Ke1 on which black during the game have planned 40…Rd4? (trying to make something like zugzwang for white) on which white had 41.Ne2! and on 41…Rd2 42.Rg6+ Ke7 43.Rxh6! (I underrated this simple move thinking that white should play 43.Bxf5? Bxf5 44.Rxh6 Rb2 with serious problems for white) Rxc2 44.Rg2 with counter play for white. Instead of this bad plan black could choose winning plan which I mentioned – doubling rooks on g7-g8 and putting bishop on f4 forcing exchanges.
40.Ne4+?
Getting caught in trap.
40…fxe4 41.Rg6+ Kf7 42.Rxh6
In this position white probably did expect 42….exf3 and after 43.Rh7+ Kg8 44.Rxd7 Rxd7 45.h6! white have good drawing possibilities. But….
42….Bf5!
Catching white rook. Without seeing this move, black would not do their 39th move.
43.fxe4 Kg7 44.Rxc6 Bh3+
Last finesse. Black don’t giving second passed pawn for white. Now black is winning 45.Rxh3 bxc6 46.Rg3+?
Bad move connected with plan va banque, which only makes faster final. Better was 46.Rh2 but after 46… Rd2 47.Re2 Kh6! 48.Ke1 Rxe2 49.Kxe2 Kxh6 black should win anyway.
46….Kh6 47.Rg6+? Kxh5 48.Rxb6 Rd2
And that is the end……
49.Rc5 Rxc2 50.Rxe5+ Kg4 51.Rd5 Rxd5 52.exd5 Kf5 53.Ke1 Ke5 White resigned
