So I've tried to tighten up and even though the first couple went ok the last 8 or so have been terrible.

Instead of getting to the 200 and 250 levels with 2800+, I'm getting there with like 1800 to 2200. We then play merry-fold-round till I would think are correct pushes but maybe they are not.

Some examples:
UTG 1600, b300/150 A9s, push? 7 left, I'm second short stack.
HJ 1400, 200/100 A10o, push? 8 left, 1 big stack.
BB 1100, 300/150 J4o, UTG all in, button calls with 1400 behind, pot is 1796 and I have to call 298. Theres 9 left and I'm the short stack. 6:1, I'd have to be less then 16.5% to make this incorrect?

It could easily be variance but I'm not used to getting to these levels with so few chips. 1 and 2 I ended up running into bigger A's and I folded the J4 hand.

But looking at my tourneys this is my biggest problem area pushing Ax hands early and running into either bigger A's, pairs or the Big Stack that decided to call 3.5bb with ATC.

Previously I didn't have to make these pushes, (again it could have been up variance) but to me it just doesn't feel natural. Not saying that it's not correct. I guess I don't know how to explain it. If it's just variance just let me have it. Sorry if it's a whine post also.

8 games is nothing...

This.

Without any reads, I'd say fold for each of those situations. The last hand is tough, but I would muck, and hope to get a chance to steal from the SB or BU.

" BB 1100, 300/150 J4o, UTG all in, button calls with 1400 behind, pot is 1796 and I have to call 298. Theres 9 left and I'm the short stack. 6:1, I'd have to be less then 16.5% to make this incorrect? "

This is incorrect although the hand may have still been a call. you have to take your pot odds and multiply by your bubble factor which I would guess was probably around 4 in that hand. so you'd need ~48% (16X4) equity if my guess is right and your bubble factor was 4
but it's hard to even take a guess without the hand history.

Also the above posters are absolutely right about your sample. I would even say
100 games means nothing.

8 games is less than nothing. Your 70 games from before was absolutely nothing, and this is 1/9th of that..
