"Okay, I'll try R - K4. I'd prefer to get my rooks off the red squares but my choices are a bit limited."

Off the red squares is good defense against the bishop but,
are you sure you want to trade rooks?!
Black can afford it, but white is short on muscle.
White is a piece behind now and as the board gets less complex, that becomes a bigger problem.
You might want to play that out for the next 4 moves to see where it heads, yah?:jointsmile:

Might help to know that black plans to hound the king while snatching up white's win options, (the pawns).:eat:
