I couldn't solve it whatever I did

any thoughts

WTF I solved it, do you just choose to completley ignore it?

oh lol i didn't notice his sideline of Kc4. Well done i guess. Just annoys me that it's already solved any yet matthew shows stupid drawish lines.

@ifoody 7...Qe4 is a bust.

However, we can use your theme with a few tweaks.

I just noticed MichaelPorcelli's post lol

Yea just messed up the ranks there, i solved it at after-noon and now 11:45PM here, i put it here wrong.

the only and the biggest problem is ka5 and not a4......in post no 10.....what if kc4??

finally and convincingly solved by MichaelPorcelli, #27

Thanks, it is a good practice one

what if after you do Ra3+ Kb5 Rab3+ Ka5

sorry I have lots of questions

bring the other rook to the 8th rank and mate him I think

think this may not work if on being checked blacks K moves diagonally towards f8, white runs out of checks?

Hmm, I believe I thought of this in the parenthesised bit where the king moves instead of promoting his pawns.  If the checks cannot be continued and Black's king threatens one or both rooks, the rooks should move on the opposite side of the board and the game will still be won.  I may be misunderstanding what you mean, though, and I confess that other posters in here have a better idea of checkmating in this situation.

Rember that in many situations letting black get a queen still leads to a win/ also giving up a rook for both pawns still wins
