18 SNG $2.25 - 47 hands Ended 10th

Played pretty decent poker until 35th hand. Couldn't let go of QQ in spite of signs I'd not win with it. Called 2 BB bet from Button. Flop was Ks 3s 4d. Just checked as did other 2 players. Turn 5c. Bet 240 to two checks and was checked raised to 480. Other player folded and I called. River was 7s. Indicating possible flush, also possible straight. Neither of which I could beat. Last player bet 550 (little under 1/3 of pot) and I called. He had Ah 2d. Had hit straight on turn.

It looks like there were three things I should have done. The first was to bet on the flop say around 1/2 the pot. If other players didn't have a K, there's a good chance they'd have folded. If they raised it's a good chance I should fold.

The 2nd, when I was checked raised on the turn I could have folded, but since the raise was only another 240, calling to see the river might be ok.

The 3rd, when the other player bet approx 1/3 of the pot on the riverI should have just folded. If I'd done that, I'd still have been in decent chip shape .

Four hands later with 8h 10s in the BB after a 2s 9h 8d flop with cheap 180 bets on the turn and river by the other player, I called and lost to Kd 9d. Though possible to get a gut shot straight it really wasn't necessary to lose those chips.

Hand 45 was very costlly to my remaining chips. As SB i had 3s 4c, no limpers so I bet 2BB to the BB and they called (blinds 200/400). Flop was 7c 5h 3h giving me bottom pair and a gutshot straight draw. I bet 1/2 the pot.and was called by BB. Turn was 5d. I and BB checked and the turn was a Qh. BB bet 200 (very small bet to 1600 in pot) and I folded. BB showed As Qd. Till the river I had him BUT I'd have been better off not to have entered that hand at all or, at best limped all the way and folded to any bet. That left me with only 415 chips.

Two hands later I had pocket 10's and went all in. Three of the other 4 players called.  Cards showed 8d 6d 3h 6s 2d, but the Button had Jd Jh and I was done.

I need to learn to be careful with my chips all the way to end and not let myself give them up un-necessarily in situations where I'm much more likely to lose then to win.
