A Couple of Hands

[The_Missile]

[Note: I posted this on the HU/SH forum but didn't get any responses, so I thought here would be the next best place to get some help from my fellow posters. Thanks, The_Missile]

The following hands are from $5 SNG heads-up style tournaments, with no blinds. They are NL style. Each player begins with t35 stack-size.

[This hand is the first of the tournament]

Hero is dealt 7c 7d

Pre-flop:
Hero checks
Villain checks

FLOP *10c 4c Jc*

Hero checks
Villain checks

TURN {10c 4c Jc)*4d*
Hero checks
Villain checks

RIVER (10c 4c Jc 4d)*4s*
Hero Checks
Villain bets 5
Hero raises to 15
Villain calls

Hero has full house, fours over sevens
Villain has AKo for ace-high

Did I play that way too slow? I had no reads considering it was the first hand of the night?

(This hand is the last of the tournament. Hero and Villain [same as before] each have t35)
Hero dealt 57o

Pre-flop:
Hero checks
Villain checks

FLOP *4 6 8 rainbow*

Hero checks
Villain checks

TURN (4 6 8 rainbow)*J*

Hero betse 5
Villain raises 5
Hero re-raises all-in
Villain calls

RIVER (4 6 8 J)*2*

Hero has straight, to the 8
Villain has 10Jo, pair of jacks

Was this hand played too fast? Obviously, I won the tournament on it, but for future reference, was it too fast? In this tournament, Villain had shown AK suited twice to take down pots, forcing me to fold low pairs (2s or 3s on flush-drawn and straight-drawn boards).
