A few hands and first day results

[pearljam]

First day of playing 50 30+3 tournaments a day I drop exactly 10 buy ins to finish off the day at -20% ROI. Assuming I am a 10% ROI player this should happen about 1 in 10 days. I was really hoping to get off to a decent start as a +ROI helps my confidence alot, sadly it is not to be. Tommarow is another day, and in the meantime, could one of u guys give me a little help on these 2 hands?

I won this hand, but I think I should have folded, at what point should I have dumped this hand? Also does anybody check this flop or fold pre flop?

Hand #2

So should I have folded this? hmm upon reveiw I think this is a push, but I dont know, anyone want to enlighten me?

hand 1: I hate calling off that much of your stack, but hes giving you too good of odds to fold on the turn. I think you can fold the river after he bets again when he got 2 callers on the turn.

Hand 2: I think i fold here
