In this game I was White and had mishandled a favorable opening to a really precarious situation, where my King is almost stripped naked. There are 2 exercises, which is Whites best move, and what is the smashing combination that wins after 26.g4?? that I played in the game? Luckily he didn't see it :whistle:

The problem here is to find a constructive move - I spent 22 minutes without seeing the light. What is White's best move? 26.g4?? Now Black moves and wins! Can you find it?

1...Rxb5+ 2.cxb5 Qa1+ 3.Kc2 Rxc5+ 4.Kd2 Bh6+ 5.Ke1 Qe5+ 6.Kf1 Rc2! 7.Qa8+ Kg7 8. Qf4 Qxh2 9.Qxd4+ Kg8 10.Qd8+ Bf8 11.R3d2 Qh1+ leads to a draw and that leads to me thinking I've missed something along the way although a good start. I'll post the answer when i actually find it lol :wall: :wall: :wall:

The second one is easy 26.g4 Rxb5+ 27.cxb5 Qa1+ 28.Kc2 Rxc5+ 29.Kd2 (29.Qxc5?? Qb2#) Bh6+. Can't exhaust to the point of checkmate but looks crushing, i.e 30.Ke1 Qe5+ 30.Kf1 Rc2 probably checkmating somewhere.

The first one is much harder. Maybe 26.Bd4 e5 27.Bc5. See no direct threats but don't like the position. I understand you were concerned with Qf5 as a threat?

1...Rxb5+ 2.cxb5 Qa1+ 3.Kc2 Rxc5+ 4.Kd2 Bh6+ 5.Ke1 Qe5+ 6.Kf1 Rc2! is fine and the solution, but now something goes wrong in your line. 7.Qa8+ is simply not possible because of black pawn a4. 8. Qa8-f4 is also exceptionally weird, perhaps you meant Qa8-e4. In that position White really has no sensible way to meet 7...Qe2+ :hmm:

Yes I was concerned with Qf5, but also Rxc5 in the long run although at the moment it does not work because of Rd8+. I will give you a bit more time to think about a possible good plan for White. There might be more, I don't know. Your 26.Bd4 e5 27.Bc5 idea is not very convincing after 27...e4! for instance 28.fxe4? Rxc5! drops the piece.

Sorry missed the pawn on a4 and also ment to be Qe4. Interestingly the problem can be redone without the pawn on a4 when the rook sac still seems to work but white now has the possibility to put his king on b3. ie 1.Rxb5.................... Qa1+. Kb3.

Of course 1...Ra8 is also very succesful.

Instead of 28.fxe4 white can play 28.Bd4. But I agree it's not convincing as black might be able to grab c4 and b5 pawns. i.e 28.Bd4 Qe6 29.Bxg7 Kxg7 30.Qc3+(attempting to save c4 pawn) Kg8 24.Rd4 Rxb5+, etc.

Given that Rxc5 is a threat you might want to consider 26.R1d2. It also open escape route for a king through d1 in some variations. But I don't see how to parry 26...Qf5.
Another option- 26.Kc1. If 26...Qf5 then 27.Rd5

I agree there are problems in the Bd4-Bc5-Bd4 variation for White. It's a mess and Black is enjoying all kinds of bee sting moves.
I am coming to the conclusion that my intended solution does not work very well either. I had thought that 26.Rd5!? solves most problems since 26...Qf5 is avoided and 26...e6 is answered strongly with 27.Bd4. However looking more carefully after 26...Qa1+!? 27.Kc2 Qf6 white is still looking for a way to consolidate the position. e6 is a threat now because Rxc4+ lands with check. Zugzwang in the middle game. Sigh. Of course I could save the draw with 28.Kb1 and just admit that the opening had been a failure, and my King's position here is too vulnerable.

In the game what happened was 26.g4?? h6? the point of Black being that after Rxc5 Rd8+ Rxd8 Rxd8+ he does not have to play Bf8 and lose the diagonal but can play Kh7. Still it is a bit slow. I played 27.R1d2 as you suggested above and 27...Qf4? 28.Qb4! apparently with clear white advantage. 28...Qe5 29.Bd4 Qe1+ 30.Kc2 Rd8?? 31.Bf2 and my young opponent resigned. Queen and Rook are hanging, and can't all be saved. A close escape for me!

Perhaps your idea 26.R1d2 right away could have been tried, and if 26...Qf5 27.g4 and Qxc5 is refuted by 28.Rd8+ Bf8 29.Qxc5 Rxc5 30.Rxb8 as earlier in the game. White is walking a tight rope! 29.R1d2 also avoids the "Epaulettenmatt" which occurs with rooks on d1,d3 and white queen on c5 where Qb2+ is checkmate. But there is a problem. After 27...Qf4 as in the game 28.Qb4 Qe5 29.Bd4 Qe1+ 30.Kc2 Bh6!! black is winning. That line was not possible in the game as black had just played h6 - what an irony.

I am not sure of White's best move, but isn't Black's best move (after 26.g4? Rxc4... as the rook cannot be re-captured because of mate on b2?) :)

Ahh!! Now I see 27.Re8+ winds up forcing the bishop back to f8... kindly disregard my earlier comment! ;)
