this question refers to the Ill. 18 plays: 16 vs 10 and 15 vs 10; and one of the Fab 4: 15 vs 10.

1) firstly, would the Basic Strategy Sr be the prefered play, when available, over standing on 16 vs 10 at high counts?

2) which of these play deviations for 15 vs 10 should i use if Sr is allowed: for standing or for surrendering, and wouldn't i surrender anyway if it where available due to the BS Sr.

i can't seem to understand the connection between the BS Sr, Ill. 18 hit/stand recommendations, and the Fab 4 Sr...

can someone clear this up.
thanks a lot.

M.
