Equity Calculation...did I screw this one up?

An interesting hand from a $22 SNG that I won today...

Status
Hero (3850) in big blind (400)
Bad guy (1000) under the gun
Random 1 (2560) on button
Random 2 (590) in small blind (200)

Hero is dealt 3[img]/images/graemlins/heart.gif[/img]2[img]/images/graemlins/spade.gif[/img]. Bad guy raises to 800. Randoms 1 and 2 fold.

Ok, here's the interesting part.

1) Pot is 1400 (blinds + 800). It's 400 for me to call. I figure I'm getting > 3:1 here.

2) I do the following math:
50% chance of overpair (= 5:1 against = 8% equity)
50% chance of overcards (= 5:3 against = 19% equity)
0% chance of bluff (any bluff is better than my two cards)
That's 27%. I'm getting over 3:1 on odds of less than 3:1.

I raise 800 to put him all in.

Flop comes:

Turn comes:

River comes:

Hero wins when bad guy shows K[img]/images/graemlins/diamond.gif[/img]J[img]/images/graemlins/heart.gif[/img]. Hero subsequently gets berated by bad guy for the "horrible" call.

Was this such a bad call? In my mind its a call that a) leaves me no worse than 400 chips behind the leader b) is in the money based on conservative preflop estimation (50% pair vs. 50% non-pair) and c) eliminates a jackass who uses a pro's name in his/her party alias.

What do you all think? Was I crazy? Am I misreading Harrington on Hold'em?

Thanks,

Mike

Actually, looking at my own post, seems like Bad guy could have kept me out of this hand by going all in. 600 to call on a 1600 pot is less than what I'd need.

What a clown.
