10$ | 6 max | HT | pre | A5o

What about shoving pre?

A5o won't have a very good post flop playability.

I found these BBvSB ranges 21-17 bb. It's for spins where winner takes it all, so I don't know whether it will be different for 6max.

Preflop all in is the best decision with your stack.

Shove or check would be my lines mostly with this. Though I would prefer to have suited version for check so mainly shoving. Problem of small raise is that if villain limp-shove we have to fold (possibly best hand) and if he calls this hand will play fairly bad postflop. Flop we can check or cbet small. Whatever we use 90 or 120 doesnt have effect on most people range they continue with so 90 is fine.

But yeah advantage of checking some Ax comes apparent when flop comes Axx and villain goes for multiple barrels.

btw @Axif1 6 max has icm. Its different. Spins and hu are cev. PIO can only do cev. They don't differ much in the early game but enough that I would to think again.
