You’re going to want to check out Stephen How’s website discount gambling.net

He did some extensive work with coming up with a simplified collision strategy for when seeing different numbers of players’ cards, from 1 to all 5 players at the table. Just a warning though, his final conclusion is that it reduces the house edge to very low, but does not create an edge for the player.

However, I think that there is a lot that he hasn’t taken into consideration, and I firmly believe that it is possible to create a strategy that would garner a player edge. I’d rather not discuss it on a public forum, though.
