My pocket cards: A5o
let's say there isn't raises preflop. Which of these flop are the best for me (no flushes - suits does not matter) and why?
1) 2 3 5 (high pair, high kicker, large posibilites of overcards)
2) 2 5 T (middle pair, high kicker, overcards posibilities)
3) 5 8 T (bottom pair, high kicker)
4) 2 T A (high pair, low kicker, no ovrecards)

Same scenario for K9o
1) 2 3 9 (high pair, high kicker, large posibilites of overcards)
2) 2 3 K (high pair, medium kicker, small posibilites of overcards)
3) 2 9 T (middle pair, high kicker, overcards posibilities)
4) 2 K A (middle pair, medium kicker, no overcards)
5) 9 T Q (bottom pair, high kicker)

I know when I go all-in A5o is better than K9o, but what is better when I don't go all-in. I think it is K9. Does that mean that I should raise whit K9 like Ax.

I play sng tournaments in Everest poker (6 players). First several times when I made to head up (4 players gone) , I didn't raise preflop except what pairs when i go all-in if short-stacked, didn't play aggressive and didn't bluff much, just check and check-raise, wait for opponent to make mistake. Half of that time I win 1st, half 2nd (1st win 70%, 2nd 30%).
Than i read that in head up I sould play aggresive, and often raise preflop ,but almost always finish 2nd ,when I bluff and opponent actualy have good hand.

When flop cames and i decided to bluff, I bet pot, he usualy call whether he have hand or not. After turn I bet pot again and if he dont have hand he fold but if he had he call and I lose almost everyting. If in turn I bet smaller amount, I usualy get reraised (very offten and he must bluff half the time), than I fold, but after several times he do it, I lose patient and go all in and always lose.

I star to play poker lately (les than month) and play sng $1 + $0.1 ,first won $4.2, second $1.8, so profit is $3.1/$0.7 , first won more than 4 times money.

Help me to be first not second, maybe I can't be aggresive, maybe is better to play like first times.

Thank you.
