I'm excited to announce that SimplePostflop has released their first two preflop solution packs which are available for sale here: http://simplepostflop.com/en/Solutions_Library?source=gtorangebuilder . If you go to the site using that link you will automatically get a 5% discount of off all solution packs. The packs give you full access to large pre-computed preflop solutions at a greatly reduced cost compared to constructing and calculating the solutions yourself (the existing two packs are in the $100-$200 range).
No SPF license is required to purchase and use preflop solution packs, all you need is a free SPF account.
Right now there are only two packs available, one by Coffeeyay with SBvsBB solutions for spin-n-go situations and one with SBvsBB solutions at 50/75/100/150 stack depths for cash players. Currently the cash solutions do not include rake but rake support as well as many more solution packs will be coming over the next few months. I'll also be personally constructing some preflop packs soon so keep your eye out for an announcement in the coming weeks.
