3bet more SCs low pairs ect Id say, he should raise such a wide range and fold to 3bets you could probably profitably 3bet any hand... depends on the rest of the table somewhat though, also defending blinds cr all the Axy Kxy dry flops, dont second barrel though

really though players who are multitabling should not be your targets since they are more likely to know what theyre doing and thus probably have less leaks/ exploitive play than non multitablers, Id say find a new table if your sitting six max NLHE at low limits with a regular whose playing like 5 to 10 tables
