A mambo / Latin-jazz montuno in block chords on a C9 vamp — Scivales's Ex. 36, which he notes also fits the opening of Mario Bauzá's "Tanga". Where the son montuno is a single line in octaves, the big-band mambo piano hits whole voicings, often in both hands, like a horn section.
The rhythm: bar 1 (the two side) is plain — chords on beats 1 and 3, both short. Bar 2 (the three side) is where the syncopation lives: a chord on beat 1, then the and-of-2, the and-of-3 and the and-of-4, the last one anticipating the next downbeat. Compare with the son montuno: the attacked downbeat is again on the two side, the string of "ands" on the three side.
Listen for the alternation of two voicings — a C9 with the 9th on top and a darker C7(b13)-flavoured chord (F, Ab, C) — so the vamp breathes even on one chord. The bass plays a standard root–fifth tumbao.
Practice: keep every chord short and even; the energy of a mambo comes from the rests. At 200 bpm feel it in 2.
