Hi , seeking to find winning plan for white if instead of 24)Qxg7 Qxr is played • page 2/2 • Game Analysis • lichess.org

"His rook control H file"

Then Qf4-Qg5-Qg7-Qg8#
Black cannot control both h8 and g7.

and what if say after Bf6 Be4 and on Qf4 just Bg6 ? at least he avoids any kind of penetration then it seems on h and g file

Then create a passed pawn with c4 and d5. The bishop no longer guards d5.

Just attack over the dark squares: Bf6, Qf4, g4, g5, Qh4, Qh8#

His rook control H file

Doesnt matter. The point is that the total material is irrelevant, what is relevant is the material that is actually in play. Usually both rooks will challenge the queen and will make it hard, if not impossible to win, but one of the rooks is trapped and it is not coordinated with the other one, so you can pick him apart before he coordinates them.

Your first mission is to make sure that the rook stays trapped as long as possible while you set up even if you cant win it immediately.

The second plan is that his position is not great, while in points you are roughly equal (pieces have a fixed value just for reference, but their values increase or decrease according to the position). Since there is one rook trapped, that rook is not worth 5 points, its worth probably 2 or 3, its worth less at the moment. So you have some extra advantage in material in play for the time being. So The second mission, if you can win material right out of the bat, is to put the opponent either in a zwug zwang or in a very passive position where his moves are not very effective.

So, assuming white is next in the last position, you play Bf6. As you can see, you trapped the king in the backrank, making the opponent to not being able to connect the rooks via the h file. Plan 1 is already succesful

The rook in the corner for sure cant go to d8 nor b8, so assuming he wants to get the g pawn and he moves Rg1 or Bxg2, doesnt matter. Same variation.
You do Qd6+. He cannot go to e8 because there is a mate, he can only go to g8, then you slide to Qg3+ (which will lose the bishop for starters), king must now return to f8 else is mated, then you throw the other check at Qg7+, forcing Ke8, then Qg1, you win the rook in the corner. Then the game.

Its the same result whether Bxg2 or Rg1. You get the rook in the corner because you repositioned the queen with tempos.

So, he cant go for the pawn, What does he do? Suppose he does Rh7, to prevent the g7+.

You can follow more or less the same plan, Qd6+ Kg8, Qf3+ Kf8, then something like Qg5.

The rook guarding g7 is stuck there due to the threat of mate, he cant move it. Maybe he can check you, but eventually has to return when he runs out of checks. Then you can use some tempos to move the g pawn forward, get the queen out of the way and then keep advancing the pawn.

The other choice he has is to try to liberate the other rook via a6-a5 and get out from the corner.

Conversely, you can go g4 straight away after Rh7. The rook in h7 will then be able to move because you dont have a threat of g7+, but the other rook cant get out of the corner, because the king is in f8 and has no diagonals, you only need to do a check in the backrank if he decides to move the a rook. But as you can see, either variation immobilizes one rook or the other. You can use the tempos to advance the g pawn or the central pawns (remember that the rook in the backrank cannot go to d8 because of the bishop).

There is no obvious mate, but it is quite obvious black is in deep trouble because he has less material in play. So, in the actual practical term, you are ahead in material.

And when you are ahead in material and you dont have an obvious mate or attack, you just make threats that need to be responded to tie up his material on the defense. But since you have more material, once he ties up all his material in defense, he will reach the mentioned zwug zwang because you have more material and tempos and can keep pressing, eventually he will be forced to do a bad move.

Just dont let those rook to connect, else he might draw. There is no clear checkmate, but the action plan is quite straight forward, tie up the h rook on defense of g7 or tie the other in the backrank defense. Then advance the pawns. He simply cant cover both flanks because the rooks are in disarray.
