...Does anyone know if there are any other 4 card player hands where it is correct to Switch and breakup a BJ?...

I've done it against a 7. Here are the notes I made many years ago...

(1) Keep a natural blackjack
….except
v7 With two pictures with <18 or to create >=(18,18) (except play AT 88)
v8 With two pictures with <19 or to create >=(19,18) (except play AT 88)
v9 With two pictures or AT99 (except play AT T2)

...I am starting to evaluate the rule changes you list above, but I have some questions.

4.(a) When the right hand has a Blackjack you can't switch

- So far, I have not noticed any hands in which it is mathematically correct to break-up a Blackjack by Switching, except when the result is to create a suited blackjack. Does anyone know if there are any other 4 card player hands where it is correct to Switch and breakup a BJ?

4 (b) If you switch and turn the right hand into a Blackjack, then you can't switch again

What does "switch again" mean? I thought there was only one decision point for switching.

4 (c) If the left hand is a regular blackjack, and the right hand is currently not a blackjack but can be turned into a Suited blackjack, then this is allowed, but the opposite is not (see "4 (a) and 4 (b)" above).

If the player has Ad-Tc + 6h-Td can you switch the tens to make a suited BJ in the left hand?
If player has Ad-2c + Ah-Td then a switch to make a suited BJ in the left hand is NOT allowed, correct?
If player has As-Th + Ah-Td it is NOT allowed to switch and make a suited BJ in the right hand, correct?

"What does "switch again" mean? I thought there was only one decision point for switching."
I don't normally play switch, but in this online version if you were playing and then realized you made a mistake by switching, you can usually switch back to the original hand, except if the right hand is/becomes a BJ. This version lets you switch as many times as you like, until you make a "normal blackjack" play, hit, stand etc

"If the player has Ad-Tc + 6h-Td can you switch the tens to make a suited BJ in the left hand?" Yes, you can switch
"If player has Ad-2c + Ah-Td then a switch to make a suited BJ in the left hand is NOT allowed, correct?" Correct, that switch is not allowed
"If player has As-Th + Ah-Td it is NOT allowed to switch and make a suited BJ in the right hand, correct?" Correct, that is also not allowed

Also, about the pairs, it is true that you can only split pairs once per game and NOT per hand.
