Who like's money.......me!

Ok, here is the first post of current poker. Following is the hand history:

$50 NL Texas Hold'em - Wednesday, May 31, 15:53:46 ET 2006
Table Table 107985 (Real Money)
Seat 6 is the button
Total number of players : 5
Seat 1: ILoveMyNuts ( $47.20 )
Seat 3: mcsoccer1010 ( $47.38 )
Seat 4: tsikatsika ( $24.95 )
Seat 6: GTS420 ( $45.75 )
Seat 2: HERO ( $57.15 )

ILoveMyNuts posts small blind [$0.25].
HERO posts big blind [$0.50].

** Dealing down cards **
Dealt to HERO [ Qs Qc ]
mcsoccer1010 folds.
tsikatsika raises [$1].
GTS420 folds.
ILoveMyNuts folds.
HERO calls [$0.50].

Normally I would re-raise this hand preflop, but tsiktsika has been playing a lot of pots, and I figure that I can get a check raise in on a safe flop (no aces or kings).

** Dealing Flop ** [ Qh, 6d, 2h ]
Hero checks.
tsikatsika bets [$2].
HERO calls [$2].

This was such a good flop (Trip Queens), that I decided to slow play it. I'm only slightly worried about a flush draw.

** Dealing Turn ** [ Jc ]
HERO checks.
tsikatsika bets [$3].
HERO calls [$3].

If he's going to keep betting the hand for me, I'm going to let him.

** Dealing River ** [ 6h ]
HERO checks.
tsikatsika bets [$4].
HERO raises [$10].
tsikatsika raises [$12].
HERO raises [$12].
tsikatsika is all-In [$2.95]

The river fills me up. I decide it's time to check raise, but how much? After his $4 bet, he only had about $15 left, so I raised enough to hopefully get him to go all-in, which he ultimately did.

HERO shows [ Qs, Qc ] a full house, Queens full of sixes.
tsikatsika doesn't show [ Jd, Qd ] two pairs, queens and jacks.
HERO wins $48.15 from the main pot with a full house, Queens full of sixes.

Personally, I think he played this hand poorly on the river. What hand am I flat calling the flop and turn bets. If this hand were played and I had the QJ, I would be worried about the flush, although AQ would be a likely holding.

What do you think?
