Though, KMAN, I would have to disagree with your analysis a little bit. Remember, this is Yamamoto we are talking about. This dude has a zanpakuto which is the oldest fire type zanpakuto and has the highest offensive capability in all of soul society. He is also skilled in every other area of Shinigami combat, where he was able to use a level 96 Hado and he was able to use it to very great effect. So great, in fact, that he did quite a bit of damage to Aizen and even Aizen commented, afterwards, that he (yamamoto) almost got him. This dude also started the entirety of the Gotei 13, being the leader of the group and judging on the original nature of this group, he probably sought out all of the original captains. Because we know that these people were bloodthirsty killers and thugs, it can be safely said that they wouldn't have just accepted Yamamoto's offer to join this organization. They were probably beaten by Yamamoto in a fight and they probably joined him because he was strong. (This concept was reiterated with the Espadas and Aizen, where the Espadas joined and followed Aizen because he was strong). This dude has been the Captain Commander since the founding of the Gotei 13 and the title has not been contested by anyone.

I do think that Dangai Ichigo is strong. Like, I really do think he is strong. But judging by what has been said above, Yamamoto wouldn't just let ichigo dodge his attacks. He would probably be going straight for the kill and Ichigo would have difficulty keeping up. I honestly do think Yamamoto would win, even though his Bankai can't be used for a long time. But this is all compensated with his skills in other areas, where he will ensure that his opponent will have so much difficulty in keeping up with his level of Kido or Shunpo that they cannot avoid being hit by Zanka No Tachi.

This is all considering current Yamamoto, who was old and frail, as compared to a younger Yamamoto. This is all considering a current Yamamoto, who would use any method at all in order to kill his enemies, including risking the lives of his own subordinates. If it was a Younger Yamamoto fighting against Ichigo, Yamamoto wouldn't even hold back for a second. He wouldn't care if his subordinates died if they were in close proximity to his Bankai. He would just activate Bankai and slash whatever part of his enemy he could get his hands on.

TLDR: Yamamoto is just too OP to be beaten by anyone. Like, seriously. The only way to beat him is to strip him of his Bankai or Zanpakuto powers. Even that doesn't guarantee victory. We still don't know what would have happened if he didn't restrict Wonderweiss from exploding(he was getting ready to use hand to hand combat against Aizen). We also don't know how it would have gone if Ywach didn't steal his Bankai but just deactivated it. So, honestly, I really don't see any meaningful way in which he can be beaten.
