I am a newbie so sorry for posting this question. I just wanted to know what I should so in this situation: I have a 15 vs a dealer upcard of 10 and its a high count. Late surrender is permitted and its a 6 deck game with typical rules. Assuming the dealer does not have a natural should I do what basic strategy dictates and surrender or do I use my index play and stand on this hand? I use the KO system if it makes a difference. But generally speaking I think late surrender takes precedence over an index play right? Thanks in advance to anybody who answers.
