Played in a 750 player MTT on Pacific yesterday but went out on the bubble (placed about 100th with top 60 ITM). Would appreciate comments/advice on the following 2 hands.

An early hand

Blinds 75/150, my stack ~1100
I get 10 10 on the button.
LP calls
I raise to 300
SB and BB fold, LP (stack ~1200) calls my raise
Flop is rags all under 10
LP checks to me – I go all in and LP folds

I always find pocket 10s and pocket Jacks difficult to play.
Even though I won this hand, did I play it Ok? Should I have gone AI preflop to get more effect from the raise or just limp in and try and catch another 10? What’s the best play in this situation?

Hand 2 – the one that killed me

Blinds 300/600, my stack ~3500
I get KJo as SB
Everyone folds to me and I complete, BB checks
Flop is 962 off suit

Given my stack, the 1200 in the pot looks very inviting
I have 2 overcards.
BB (stack 2600 – a little less than mine) is an aggressive player and will definitely raise if I show weakness.

In the heat of the tourney I go AI-trying to project strength
BB calls AI with 86o. His pair of 6s hold up and I’m left with ~300 chips and soon end up out!

Not sure if I’d have made it into the money playing ultra-tight given my stack size
I realize the AI was a bad play. But would it have been better to make a pot sized bet and back off if he raised or just check and prepare to fold if he bet?
