Hopefully Full Shapo mode when it stays I’m not the usual shank error fest that shapo can beImpossible to predict, so I will try to do exactly that.
The main reason being Zverev. Dude is just unbelievable moody and he can go from total clowning to unplayable and back very fast and with no warning. His FH seems to improve and became a weapon, of course not as good as his opponent, but not a liability. BH is fantastic and if he was able to execute a coherent plan, he should pepper Tsitsipas worse side until it breaks. And it will break eventually as it always does.
So, from Tsitsipas point of view, he should take every chance to dictate with FH. Actually, I think he should be more aggressive than he is from that wing. I have a feeling that in today's coaching a lot of emphasis is put on percentages and "margins", restricting people with serious talent. We would never see Fed's FH today as it would be marked as too risky. So, go full Shapovalov and unleash it Stefanos.
