This is Muay Thai

Off your opponent's jab you are going to set-up elbows. From a high guard, roll your ipsilateral glove to cover half your face, palm toward you. Cover and check with your lead hand.

Check lightly with your lead hand then slap their jab wide and step forward to deliver a straight elbow

Next try slapping their jab inferiorly and laterally with your rear hand, stepping in with the rear horizontal elbow.

If they clinch instead, control their triceps with your lead hand and overhook with your rear hand. Place this hand on their low back and come in close, feet parallel.

If they grab your shoulder with their hand, wrap their arm with your overhook and use this same hand to grab their contralateral biceps, trapping (submitting?) their extended arm. Deliver a sky-to-ground downward elbow.

You can also use your overhook to put your glove on their upper arm. Drag down their arm and throw the rear horizontal elbow.
