FT - 3 remaning

[SengioKang]

This hand is from FT of UB 2.20 buyin bounty... just checkin if play is OK

Blinds 5/10k...Antes 1k... pot 18k PF

Villian on button w/ 485005 raises to 40,000
SB posts 5000 has 220k behind folds
WuKang w/ 95285 posts 10,000 blind
w/ Ac4c pushes all in for 85k

read on button. pretty solid values, but was making more raises lately 3rd in last 5 hands.

Right shove w/ M of 5 or is Ace too weak??? or does Flush draw and straight draw make up for inherent weakness of A?

Can i dump the puppypaws and fold into redzone here???
