When should the big blind call with JTs?
JTs calls every time as the big blind up to 17.5bb. At 17.5bb its call is worth -0.8280 big blinds against -1.0000 for folding. At 17.5bb a call breaks even at 47.1% equity, because the big blind has already posted a full blind that folding gives up. At 18bb it mixes, so either choice is close to break-even at that stack. At that stack the call is worth -1.0000 big blinds, level with the -1.0000 for folding. Past 18bb the chart folds it.

What makes JTs different from similar hands?
JTs is 4 combos out of the 1,326 two-card hands and ranks number 45 of the 169 starting-hand classes by equity against a random hand. From the small blind, JTs and JTo both shove at every stack from 1 to 20bb. From the big blind, JTs calls cleanly 5.5bb deeper than JTo (17.5bb against 12bb). Suited hands win more often because of flushes, which is why the suited version is the more playable of the pair.
Where can I check other hands like JTs?
The stack pages show the full shove and call charts at each depth, and the hands closest to JTs in strength, along with JTo, have pages of their own. The combos page counts the specific hands that make up JTs and how card removal changes them.
How were the numbers for JTs computed?
We solve a chips-only game for two players: small blind 0.5, big blind 1, no ante, equal stacks. Starting hands are the 169 classes, weighted so that shared cards are impossible, and equity comes from counting every five-card board. The solver plays itself with best responses, averages them, and fixes the hands on the edge so they are exactly indifferent.
