For chest this is my routine:
Wide Dips: 1 x Failure (assisted or unassisted)

Push Ups: 1 x failure to 1 x Failure.
This is a regular push up (with knees off ground). As soon as you get to your failure, drop your knees to the ground immediately and do more push-ups until you can’t anymore.
Freemotion Raise: 1 x 12

Also bring palms inward as you are coming up so your hands touch when at the top of the motion while squeeze pecs when you are coming up are at the top. This is killer for lower chest development and a lot better than declines IMHO because its an isolation exercise.
Machine Fly: 1 x 10 heavy
Incline Dumbbell Press: 1 x 6 heavy full rep, and then 1 x failure half rep. I just do 6 full reps with as heavy of a weight as I can go to so at 6 I'm really struggling then blast out half reps till I can't anymore.
No rest between sets, I repeat above x 3 with 3 min rest between repeats.
