Does removing an obviously unused portion of a range speed up preflop calcs?
Not right now but maybe I manage to add it to the next update if not, then to the next after that.

For example, if I remove a significant portion of BB's potential range defending vs EP raiser, will that be helpful?
No for reasons different than just me not adding it. Only removing hands from both ranges has potential to speed it up significantly (removing them from one speeds it up but it's a very minor effect).

What about going into a node or two once a tree is constructed, and before starting the solver, to quickly make a very rough strategy to jumpstart the solving
This idea in general is hard to pull off and didn't work with all my tests so far.
The reason is that say in a flop tre 98%+ of the data is on the river and in preflop solving 99.9%+ of the data is on the flop+. Those places in the tree needs to be solved and it will take comparable time to do that regardless what starting flop strategy is.
There are surely tricks to pull it off but I was never able to make anything significant out if this idea.

Wondering about any practical ways to speed things along. Keep up the good work!
For now the best one is to wait 2-3 days, the updater will be significantly faster (20%-35% depending on computer + a bit faster convergence).

Hi, I wonder how preflop solver knows that in 6max utgvsbu oop is utg and he act first pre flop, and buvsbb bu is oop but he acts second pre flop.
In the full preflop tab you can choose blinds for IP and OOP (those describe postflop play), so:
1)SB vs BB on a HU table:
-IP money in the pot: 5
-OOP money in the pot: 10
-dead money: 0
2)SB vs BB on a 6max table:
-IP money in the pot: 10
-OOP money in the pot: 5
-dead money: 0
3)BTN vs BB on a 6max table:
-IP money in the pot: 0
-OOP money in the pot: 10
-dead money: 5
4)UTG vs BTN on a 6max table:
In general impossible to solve because there are two more players to act but if you want to solve after BTN already 3bets:
4)BTN vs UTG on a 6max table, after BTN 3bet:
-IP money in the pot: 0
-OOP money in the pot: 0
-dead money: 15
and force (add only those lines to the tree) say bet 30 and 3bet to 90, after that add 4bet/call/fold.
Also always build a tree on 5 flops first and go browse it for a while before solving to confirm it is what you want. After that go back, rebuild on as many flops as you want and start solving.
The last case will be way slower than it should be in this release so maybe it's better to wait with those.
