55 vs JT is the classic preflop race — a pocket pair against two overcards (connected overcards). Here the overcards actually edge in front: JT wins 50.2%, 55 wins 49.0%, and 0.8% of boards chop. The unpaired hand has six outs twice over (any Jack or Ten), and with its straight gappers live too the whole thing sits within a few points of a coin flip.
Think in variance terms: 50.6% equity means JT loses this all-in nearly 49 times in 100, so even a "dominant" spot is a coin you'll see come up tails plenty. Getting it in as the 50.6% favorite is correct every time; the 49.4% that goes the other way is math, not a misplay.
Practically, treat 55 vs JT as a flip: get the money in when you have fold equity or a tournament reason to gamble, and don't agonize over who's "ahead" — the edge is too small to fold a hand you've committed to. The mistake isn't taking this race, it's taking it for a deep stack with no dead money in the pot.
