I got Ah Ac I raise 3X the BB to 150. I get two callers. Total pot is 450.

The flop is Kd 10d 3d

The first guy to act immediatly goes all in for 960 chips into a 450. The second guy thinks for a little while and folds. Now I am thinking there is no way this guy has got the flush he wouldn't go all in. At this point I don't think he has a diamond either. To me the huge bet was to protect his hand from someone calling with a diamond. I took the entire time to decide and I put him on K 10. So I folded.
