I like this play a lot. Great move. The push leaves him with a way out(enough money left to play) if he folds.
The amount of outs you have is insane 9 diamonds, 2 each of 9's and A's (not including the diamonds of course) and 3 each of J's and K's= 19
You could probably take a few away if you include his hand.

Once again I love this play.
