the min raise can be scary but without a SOLID read, no way am I laying down. I may just push all in with my initial raise to begin with. However, raising is fine but I'm likely pushing on any flop if I get a caller hoping they fold if I missed.

The only thing I can see that you did wrong was betting 850 preflop and only leaving yourself 110 behind. This is the point where it's all or nothing. Since you're probably getting that last 110 in after the flop may as well commit it preflop and put villain to the big test.

Just bad luck that AK ran into AA, really. I would have gone broke here as well.

thanks, i thought thought betting 850 was putting me all in, thats why i did that, i defintly wanted to go all in preflop. there was no way i was folding no matter what
