Put an overpair in against suited connectors and AA vs 64s is the result: AA wins 78.9%, 64s wins 20.6%, and 0.4% of boards chop, a 3.8-to-1 edge. Suited connectors are the single best class for cracking an overpair — two live ranks, straight potential off the Six-Four gap, and a flush draw stack up to about 1 win in 5, well above what an offsuit holding manages here.
Translate that into a decision and it's simple pot-odds math: counting split pots as half, AA carries 79.1% equity and 64s 20.9%. Against a pot-sized shove you need about 33% to call and about 25% versus a half-pot bet — so 64s needs real fold equity, not just its raw share, to justify stacking off.
AA should play this fast and deny equity: every free card helps 64s more than it helps you. If you're the one with the suited connectors, lean on implied odds and fold equity rather than the raw 20.6% — the hand's value is in the pots you take away postflop, not in flipping all-in preflop.
