is mate possible here.

main question is whats my best move when i play:

22 ... Rxb2 - which i played as couldn't see any obvious mate i could force, and leaving a possible fork with my knight on the next move.

also at the end my opp resigned, is this a bit premature?

27 Kg1

then how does black play, castle to protect my king at the back, or Qg3.

this is my first post, so please be gentle

After Kg1, how does white defend against Nf4?

he doese Qf2 witch will prevent checkmate

attacking the bishop by the rook (Rxb3) then try to attack the Rook which the bishop was defending it by ur queen then try to take his another Rook by ur queen again ,don't castle right now only after these moves ( that's in my opinion )

I would have done Re2+, followed by Ng2+, forking the king and queen

oh yeah, that works, but i lose a rook and a knight no?

Am I missing something? In the original game there is a rook on b2.

there is yeah

Yes, mate is forced and in fact rather trivial.

nope i think RxPb2 is the best thing to advance from that position! It opens up the king more than anything else i can see! And you are under no threat of attack so your king is safe in the centre

...waht? There is no pawn on b2.

EDIT: Ignore me, I'm an idiot; I just realized you meant move 22.

thanks! very exhaustive analysis there. cheers

I have to thank setanator for the key move 27. ...Ne3 though, it creates multiple powerful threats (and blocks the white queen's access to the vicinity of her king, which is subtle but significant). I didn't bother looking through moves other than that, so I basically stole his solution. :P
