If you activate Voldo's LF B+K armor with 2B, you can RCC 1B+K to avoid the UB attack he does and he has no way of avoiding 1B+K.
Also versus Voldo, if you block any of his Landfish attacks (barring LF (A) and LF B BE, which you should JG), you can punish with WR B if he tries to keep attacking. If he does 2_8 after a LF attack the WR B will hit off-axis and the followup combo won't work (this happens consistently), and if he does LF K, WR B won't combo. However, if you predict LF K, 44K will connect against it for about 40 damage.
If you block 22(B) and do 2A, if he does BS B+K both attacks will whiff but his recovery is so long you get a WR B punish. This is a bit of an option select as it covers both BS 2A+B and BS B+K after he enters, which are the common evasive methods of staying in Blind Side.
BS 2A+B goes underneath 66A and 3K. Be warned.
WR B combo has a different timing and different followups against BT opponents. Generally you should do the BT B+K immediately instead of delaying it, then do 8B+K → 44K_44BAA. The 44K version does 101 damage (!). Due to the pushback of 2A+B preventing you from punishing it with WR B except at a close range block, it's recommended that you run forward and 2G when you expect it.
