It's a lot better if you can shove over a PSB.

We're trading the chance to (1) maybe get it in as a big favorite vs lower PPs for (2) the chance to avoid some flips and pick off some C-bets. The smaller he cbets the less value 2 has. Also with 2 we risk getting outplayed or getting it in almost dead vs a hand that might have folded pre - say KJ or QJ.

I think either way is OK as long as we're playing 1 over non A flops.

If you have seen him raise/fold a lot pre I would lean that direction.
