b4 is good too
Not so good as it can be thwarted with 1...Qa6+.
but after b4:Rc5 is check and white can escape with rook
No, 1. b4? Qa6+ will lose the game for White, who cannot 2. PxRc5+ because White first needs to move out of check 2. Kf2 Bg3+ 3. Kxg3 NxRf5+ 4. BxNf5 RxBf5 now it's mate in 9 for Black. OR block check with 2. b5 QxRb7 3. Now what?
The puzzle line is the only solution
Wow! That was a lot of fun and it was pretty sneaky too!
