Two hands versus maniac

[drtofu66]

I've been in a downswing and am seeing monsters under the bed. For the first hand, I should've discounted that he had QJ, I think. Horribly played hand (my only defense is that I've been getting shellacked this month-- stuff like JJ vs a passive QQ who just calling me down, let myself get stacked with an overpair vs set on a 6 high flop, etc. Down 5 buy-ins this month).

I didn't have a much info on this guy yet. He'd been loose (VPIP of ~50% over the first 9 or so hands he'd been at the table).

Hero...

I always manage to screw this up. Do I check and let him represent the flush on the river, risking losing some value if he smells a rat? Value bet 1/2 pot, hoping it looks weak (stacks don't seem deep enough for him to want to stick the rest of his in)? And half of me is expecting him to turn over KcJc, I've been running so bad...

hand 1 seems fine.

hand 2 i push river.

[ThelVlaster]

Hand 2 you only have $1.50 behind, easy push and it should get called more often than not.

Oops, I didn't notice that the hand converter screwed this one up. My stack is $24.60 and villain's is correct.

[two empty seats messed this one up. OP fixed]

For the first hand, villain showed 5d2d. Given this info, are we better off trying to let the villain represent making the flush on the river or are we assuming he already did and will call a push?
