Indeed this is hopeless now. You can't avoid losing lots of material here. My white bishop was dominant, you had to be very careful to parry the threats. Wc2 was a nice attempt at luring me into a mate-in-one!
Do you want a break before the next game or do you want to start within a day or two? You can take up to 14 days if you want.
