I NEVER SEEN THIS ON FINAL TABLE

Last 6 on Final table ( mtt , ko)
1. 470e + 50e mtt tickets
......
6. 120e
.....
Ko is 50e for every player .
I am fourth (28 bb)
I am on
EP AKo (diamond,spades) , rfi 2 bb
all fold to BB .
HE ( 29 bb ) goes instantly ALL IN .
I CALL
He have 98 clubs ?!!!!
FLOP A67 clubs (he got a flush).
.....................
I play more than 20000 mtts , many of them are 100 to 600 players, also play many many final tables BUT no one ever ever goes like that 3B all in (HE HAVE 29 BIGG BLINDS )
............
I play on pokerstars, GG poker, 365 bet, 888, etc.

If he had only done a CALL, he would have gotten the flush anyway, but he wouldn’t have been able to take all my chips.
Only this way could he take everything from me and double his stack.
This is a lesser-known site, and I’m really suspicious—it just feels unreal that he pulled this off.
I’ve come across all kinds of players, but in the finals even the “crazy ones” usually calm down and play it safe, but this today was ridiculous.

What you think?!!
