hm interesting at first i thought that failed to 21.Qxf7 Rxf7 22.Bxf7 threatening mate but black does have 22...h6 after that, srviving the attack. 23.Nc3 threatens Rag1... sorry I'm doing this is my head that's as far as I can go

Yeah but Qf7 is just stupid, losing the rook, but I think this new variation is better :)

yeah drops a rook and bishop.. after Rg1 would Qxe5 be an option? looks like it actually works

In which variation?

 after 19.Kg2 Qxe5

Oh yeah that also works, but Bf5 seems stronger :)

i didn't see that that seems to be a better move

here is my full anaylsis

the Bf5 line is the crucial one here... does anyone have an engine they can analyze this with?

Nc3 looks good, and it is natural, gets my a rook into play

after Nc6 it looks like your threat has been nuetrilized but extremely accurate play is required

lets look farther

look for the line in red

why did black give up a pawn?

I really need to get my fritz fixed, I want to analyze this bad

yeah

20. Nc3 c6!

(21. Qa5 h3+ 22. Kh1 Qf3+ and mate)

c6 Rf1! I don't have to move the queen you know

Then black just wins with Qg5+ followed by cxd5...

It was the A rook Raf1 sorry for the confusion

so the line would look like this

Qd6 wins

here is the other line

 essentialy neither of us can make a mistake
