My Chess Blind Spot

There is never any shame in losing, more so it's important to admit where you went wrong and look to improve.

I've been recording my tactical training and going over what I miss. A recurring theme is missing Zwischenzug ... in between moves of my opponent.

Can you solve?

White to move

I aimed to get to an ending with Bishop and wrong coloured Rook pawn which is a text book draw.

With this in mind, I saw 1. Rc7 c1=Q 2. Rxc1 Bxc1 3. g4 h4 which is drawn.

For all this "strategy", I missed (an obvious) zwischenzug by Black. Namely 1. Rc7 Bf4+ (forking King and Rook)

For me, missing these zwischenzugs is a reflection that I'm not working hard enough for my opponent.

I'm making his moves such that they'll cooperate with my plans

I should be working harder to find flaws in my ideas and refute them

Can you see White's tactical motive?
