bounty hunters

craigcu12

i decided to try a bounty hunter but two hands really got me puzzled with how to play in these tournements
i already raised before that shove so when the other person shoved i thought surely it would be QQ or AQ+
so why would he/she waste chip with a hand like this should i have just made  the call

p1	Small blind		10.00	10.00	2600.00
p2	Big blind		20.00	30.00	1950.00
	Your hole cards	J Q
craigcu12	Raise		60.00	90.00	1870.00
p3	Call		60.00	150.00	2960.00
p4	All-in		425.00	575.00	0.00
p5	Fold
p1	All-in		2600.00	3175.00	0.00
p2	Fold
craigcu12	Fold
p3	Fold
p1	Unmatched bet		2185.00	990.00	2185.00
p1	Show	5 6
x	Show	5 K

and this hand i did a raise of 4xbb yet a call is made with A2os and most of the game i was folding so why would he/she not expect me to have a good hand

one other piece of advice i would like to ask is what should i build my bankroll to before i next enter a bounty hunter because i have had these strange calls a few times now and am starting to think that bounty hunters can be a much greater risk for low bank rolls.
i two out of 3 regular tournements i finished well yet these i just can't get far at all.

Hand 1 - Obviously just a guy chasing a bounty. You'll often see when 1 short stack goes all-in, the inexperienced players are desperate to try to get him on his own, hopefully win a race so they can take a bounty (you shouldn't be chasing bounties with junk like 56o obv).

Hand 2 - Most people in these cheap BHs are paying zero attention to how often you play a hand, what hand you might have etc. Bad players like raggy Aces

All tournaments are really high variance, so if you were gonna play nothing but MTTs on Sky where they'll usually be like 100+ runners, I'd want about £100 to be playing £2 MTTs
