You sit on your opponent's hips or chest. One of the most dominant positions in BJJ: you see everything, you control how he moves, and you have plenty of attacks.
Goals · in order
I
Stabilize
Take control and settle the position first. Before you sit up, stick to him and spread your arms wide and far. Find a stable place for your hips and knees.
II
High mount
Your legs behind his elbows: you trap his arms and open attacks on the arm and the neck.
III
Tight knees
Knees pinched tight shut down the elbow escape. That's what keeps you on top.
IV
Attack the arm
Americana or armbar when he extends. Don't just sit there.
V
Follow the escape
When he turns to his belly, take the back.

Your mechanic
High mount (legs behind his elbows)
His reaction
Bridge and roll (upa)
Your answer
Sit too low on his hips and the bridge is easy: he rolls you to the side without effort. Watch for him trapping your arm and leg on the same side: that's usually the setup for a roll that way.
#
2
Your mechanic
Knees tight to his sides
His reaction
Elbow escape (shrimp)
Your answer
Once your knees open, he has room for his knee and gets back to half guard.

3
Your mechanic
Weight balanced and forward
His reaction
He bucks you off with a strong bridge
Your answer
Without your counterweight and a grip, that bridge can roll you to the side.
Common mistakes
Rushing without stabilizing first
He can buck you off, or turn and escape.
Sitting too low on his hips
Easy bridge and roll: one hip bump and you're over.
Knees too wide
You give him room for the elbow escape and lose mount to half guard.
Leaning forward without controlling his arms
A strong bridge throws you forward and he ends up on top.
