i think that 3 handed its fold turn, both of the rivals were unknows

Flops fine obvs, we are too short to fold turn, so I would play the same. Flop size is good imo, shoving is ok but not as good I think.

Id raise 1300 flop 800 is only a 600 raise to guy...

I'd probably shove flop given it's so drawy with another guy behind. Like a normal raise HU. As played I'm giving up on that turn.

I'd give up on that turn as well... it's horrible

Yep. You were either crushed on the flop or are crushed now. C/F seems bad but really isn't given what came down. +1 to just shoving flop 3-way.

I would just call the flop to control the pot size. Yes, we are giving our opponent a free card, but a lot of cards (7,8,9,T,J,Q,K) will give villain the best hand a majority of the time. I would snap c/fold the turn for obv reasons. Your only hope is that villain is a complete donk who thinks Jx or whatever garbage is good on this board. If you insist on raising though, id just shove on the flop.

Oh, but none of this would've happened if you just shoved pre (which i think is the best option).

EDIT: Didn't notice the guy behind you on the flop. Shoving may be the best option on the flop. At these stakes, your small raise means nothing to these guys. Shove flop. But more importantly, next time shove pre!

C/F turn

call or raise bigger like suggested above has to be both levels and are unbelievably bad options.

id make the flopsizing even smaller sometimes but 800 is fine.....
