Looking at Chan's call from his perspective, it is probably the right move. Let's say he puts Moneymaker on an ace, but no flush draw. Then, Chan has 9 heart outs plus 4 gutshot straight outs. Add in runner-runner ks, 5s, or k5, and he probably thinks he is actually a slight favorite, about 11:10. Combine that with his shortstack and a good-sized pot, seems like as good a time as ever to push in the rest of it.
