 CERTIFICATION

I, Steven M. Anderson, certify that:                                            

1.   I have reviewed this report on Form N-Q of Mellon Optima L/S Strategy Fund,
LLC (the "Registrant");                                               

2.   Based on my knowledge, this report does not contain any untrue statement of
a material fact or omit to state a material fact necessary to make the
    statements made, in light of the circumstances under which such statements
were made, not misleading with respect to the period covered by this  
report;                                                               

3.   Based on my knowledge, the schedules of investments included in this       
report, fairly present in all material respects the investments of the
Registrant as of the end of the fiscal quarter for which the report is
filed;                                                                

4.   The Registrant's other certifying officer and I are responsible for        
     establishing and maintaining disclosure controls and procedures (as defined
 in Rule 30a-3(c) under the Investment Company Act of 1940) and internal
 control over financial reporting (as defined in Rule 30a-3(d) under the
Investment Company Act of 1940) for the Registrant and have:          

a.  Designed such disclosure controls and procedures, or caused such  
disclosure controls and procedures to be designed under our   
  supervision, to ensure that material information relating to the
       Registrant, including its consolidated subsidiaries, is made known to
       us by others within those entities, particularly during the period in
which this report is being prepared;                          

   b.  Designed such internal disclosure over financial reporting, or caused
         such internal control over financial reporting to be designed under our
         supervision, to provide reasonable assurances regarding the reliability
        of financial reporting and the preparation of financial statements for
    external purposes in accordance with generally accepted accounting
principles;                                                   

     c.  Evaluated the effectiveness of the Registrant's disclosure controls and
   procedures and presented in this report our conclusions about the
       effectiveness of the disclosure controls and procedures, as of a date
      within 90 days prior to the filing date of this report based on such
evaluation; and                                               

d.  Disclosed in this report any change in the Registrant's internal  
        control over financial reporting that occurred during the Registrant's
most recent fiscal quarter that has materially affected, or is
   reasonably likely to materially affect, the Registrant's internal
control over financial reporting; and                         

5.   The Registrant's other certifying officer and I have disclosed, based on   
our most recent evaluation, to the Registrant's auditors and the audit
     committee of the Registrant's board of directors (or persons performing the
equivalent functions);                                                

   a.  All significant deficiencies and material weaknesses in the design or
  operation of internal control over financial reporting which are
   reasonably likely to adversely affect the Registrant's ability to
   record, process, summarize, and report financial information; and

   b.  Any fraud, whether or not material, that involves management or other
    employees who have a significant role in the Registrant's internal
control over financial reporting.
